How Granular Delegated Admin Privileges (GDAP) allows Sentinel customers to delegate access
Simplifying Defender SIEM and XDR delegated access As Microsoft Sentinel and Defender converge into a unified experience, organizations face a fundamental challenge: the lack of a scalable, comprehensive, delegated access model that works seamlessly across Entra ID and Sentinel’s Azure Resource Manage creating a significant barrier for Managed Security Service Providers (MSSPs) and large enterprises with complex multi-tenant structures. Extending GDAP beyond CSPs: a strategic solution In response to these challenges, we have developed an extension to GDAP that makes it available to all Sentinel and Defender customers, including non-CSP organizations. This expansion enables both MSSPs and customers with multi-tenant organizational structures to establish secure, granular delegated access relationships directly through the Microsoft Defender portal. This is now available in public preview. The GDAP extension aligns with zero-trust security principles through a three-way handshake model requiring explicit mutual consent between governing and governed tenants before any relationship is established. This consent-based approach enhances transparency and accountability, reducing risks associated with broad, uncontrolled permissions. By integrating with Microsoft Defender, GDAP enables advanced threat detection and response capabilities across tenant boundaries while maintaining granular permission management through Entra ID roles and Unified RBAC custom permissions. Delivering unified management of delegated access across SIEM and XDR With GDAP, customers gain a truly unified way to manage access across both Microsoft Sentinel and Defender—using a single, consistent delegated access model for SIEM and XDR. For Sentinel customers, this brings parity with the Azure portal experience: where delegated access was previously managed through Azure Lighthouse, it can now be handled directly in the Defender portal using GDAP. More importantly, for organizations running SIEM and XDR together, GDAP eliminates the need to switch between portals—allowing teams to view, manage, and govern security access from one centralized experience. The result is simpler administration, reduced operational friction, and a more cohesive way to secure multi-tenant environments at scale. How GDAP for non-CSPs works: the three-step handshake The GDAP handshake model implements a security-first approach through three distinct steps, each requiring explicit approval to prevent unauthorized access. Step 1 begins with the governed tenant initiating the relationship, allowing the governing tenant to request GDAP access. Step 2 shifts control to the governing tenant, which creates and sends a delegated access request with specific requested permissions through the multi-tenant organization (MTO) portal. Step 3 returns to the governed tenant for final approval. The approach provides customers with complete visibility and control over who can access their security data and with what permissions, while giving MSSPs a streamlined, Microsoft-supported mechanism for managing delegated relationships at scale. Step 4 assigns Sentinel permissions. In Azure resource management, assign governing tenant’s groups with Sentinel workspaces permissions (in the governed tenant), selecting the governing tenant’s security groups used in the created relationship.

Welcome back to What's new in Microsoft Sentinel. In June, Sentinel SIEM’s Advanced Security Information Model (ASIM) broadens its normalization, so one analytic rule can reach more sources with less per-source work and, additionally, two new ASIM schemas can now bring asset inventory and AI agent telemetry into common form. In Microsoft Sentinel data lake, the Agent Identities Asset Connector adds the identity context behind your AI agents, helping you see who owns an agent and what permissions it holds. In Sentinel MCP, graph tools help security teams investigate threats and optimize security coverage by visualizing relationships across identities, devices, alerts, and signals in a unified graph experience. Read on for the details, and explore the resources at the end to go deeper. Sentinel innovations: Sentinel SIEM Sentinel data lake Sentinel MCP Microsoft Security Store Sentinel SIEM Advanced Security Information Model (ASIM) parsers and schemas [Generally available] The Advanced Security Information Model (ASIM) in Sentinel normalizes logs into common schemas, so one analytic rule can cover many sources without managing each native schema. ASIM coverage has expanded across more Azure services, broader AWS CloudTrail activity, and a range of third-party firewall, identity, and proxy products, so your detections reach more of your environment with less per-source work. Two schemas also join ASIM: Asset Entities normalizes asset inventory so you can correlate files and assets across investigations, and AI Agent Events normalizes telemetry from AI-driven workflows and autonomous agents. Browse the ASIM parsers on GitHub to explore, file issues, or contribute. Learn more in our blog. Sentinel transition to Defender blog series By March 31, 2027, all Microsoft Sentinel customers transition to Defender. This six-part series guides you through moving your Sentinel experience from the Azure portal to Defender, where SIEM, XDR, threat intelligence, AI, and automation come together in one experience. Your analytics rules, playbooks, workbooks, log analytics workspace, and access assignments all carry forward while the operational layer becomes more connected and intelligent. Starting early matters because you realize the benefits sooner, including a unified incident queue, cross-product correlation, Security Copilot, Sentinel data lake, and SOC optimization. Across the six-part blog series you get 1) the strategic shift, 2) the anatomy of incident and data changes, 3) detection and automation, 4) the governance shift across roles and access, 5) a readiness playbook with the adoption helper and cost guidance, and 6) a look at the AI-first SOC. Each part stands alone, so you can read in order or jump to what matters most to you. Sentinel data lake Agent Identities Asset Connector [Public preview] The Agent Identities Asset Connector brings identity context for AI agents into Sentinel. Activity connectors like Agent 365 and Microsoft 365 Copilot already show you what AI agents do, but activity alone cannot tell you who owns an agent, what permissions it holds, or how it is governed. This connector fills that gap with four asset tables covering agent owners, agent identities, agent blueprints, and the service principals tied to those blueprints. Together they form a connected agent identity graph you can trace from owner to identity to blueprint to permissions to the resources an agent touches. Joining this asset data with activity data in Sentinel data lake lets you detect anomalous behavior relative to permissions, spot over-permissioned or misconfigured agents, and follow full execution chains for end-to-end traceability. To get started, install the Agent 365 and Microsoft 365 Copilot solutions in Content Hub and enable the asset and activity connectors. Learn more. Sentinel MCP Sentinel MCP graph tools [Public preview] Microsoft Security Graph MCP tools, recently introduced in the Microsoft Sentinel MCP Server data exploration collection helps security teams investigate threats by exploring relationships between identities and device assets, and threat and activity signals ingested by data connectors and surfaced by analytic rules. Starting from an alert, analysts can follow the exposure path across connected entities — tracing lateral movement, understanding blast radius, and identifying configuration gaps — all from a single, interactive workspace. The tool provides a clear graph view that highlights dependencies and makes it easier to understand how content interacts across your environment. This helps security teams assess coverage, optimize content deployment, and identify areas that may need tuning or additional data sources. Executing graph queries via the MCP tools will trigger the graph meter. Learn more.

Microsoft Sentinel platform offers a growing list of tools and features, with graph being a cornerstone capability. Sentinel graph is a relationship-first method for organizing and querying data within Microsoft Sentinel data lake. Activities amongst entities (users, devices, emails, IPs, applications, etc.) become a navigable structure that avoids a complex table structure. Rather than stitching together data and evidence via complex joins, users can follow multi-hop connections in order to understand insights such as blast radius, unseen pivots in malicious behavior, and investigative details that may not be as obvious within regular logs, all while visualizing these paths to assist in communicating evidence and findings. This blog will walk through how to create custom graphs using GitHub Copilot chat experiences in Sentinel VS Code. And how to leverage out-of-the-box graph samples to build custom graphs addressing security outcomes. Custom graphs are available in public preview. Prerequisites and Tooling Sentinel data lake enabled in the tenant, this is where the data for the graph will be stored. Users will need read/write permissions on Sentinel data lake data. And either security operator or security admin permissions to save a custom graph in the tenant. Visual Studio Code (VS Code) will need to be installed, as it is essential for building and saving graphs. The Jupyter notebook extension, Microsoft Sentinel extension, and GitHub Copilot extension will need to be installed from within VS Code. These are key pieces for configuring and managing graphs. (Optional) Microsoft Sentinel MCP server if using MCP tools like the data exploration tool. Building a new custom graph The starting point is within Visual Studio Code (VS Code), where the custom graph will be built via GitHub Copilot and the Sentinel graph authoring tool. Make sure to have a GitHub account logged in within VS Code, then start a chat with Copilot via View > Chat. This will open a chat window on the right side of the screen. Determining security telemetry for investigation If unsure about which tables are available within the environment or the columns to focus on for hunting/investigations, turn to the Sentinel MCP server. With the Sentinel MCP server, users can explore the threat landscape within their environment as well as see which data sources currently exist within the Sentinel data lake. This process can be done using natural language with Copilot to obtain the information needed to perform the task at hand. “List the most important tables within my Microsoft Sentinel data lake environment that would build a blast radius for a compromised user account. List the best columns to use for this scenario. Format the response as a table” The tables and columns that can be used are now known. The next step is to use these tables to construct a custom graph with help from GitHub Copilot. For this example, a blast radius graph will be built to assist in reviewing the impact of compromised accounts within the environment: “List the top 5 compromised or targeted accounts within my environment. List which types of attacks are involved with those accounts. Summarize the information into a simple to read table” Given this response, there are a few options for going forward: Return to the Microsoft Defender portal and attempt threat hunting/review this with other analysts Ask Copilot to provide threat hunting queries or perform incident investigations for the top users who are most targeted Build custom graphs to visualize threat data around the most targeted accounts For this example, we will use option 3. Building graph mappings with GitHub Copilot To begin building a custom graph from scratch, a new prompt is submitted, this time tagging the Sentinel extension’s graph authoring tool. An example of the type of prompt to use is below: “@Sentinel /graph-authoring I want to investigate the blast radius of a compromised user and what systems/ app/ devices that they accessed based on users authentication activity. Please use at least SignInLogs, NonInteractivelogs, DeviceLogon, Onprem AD logs, IdentityInfo, and AADRiskyUsers. The graph should help investigate the following security outcomes: What is the user's current risk level and risk score from Identity Protection? Which applications and resources did a user authenticate to? Are there sign-ins from risky IP addresses, Tor exit nodes, or anonymizers? Are there non-interactive sign-ins from unexpected locations or devices? Which machines did a user log on to locally/remotely (RDP)? Which user accounts have been active on a compromised device? A few guidance for data ingestion: Ensure to filter out any data that has NULL or empty values for key Nodes and Edges Filter all data for last 14 days Do not map json arrays as Keys in Nodes or Edges” Note: To ensure that the graph that is written matches the desired scenario, it helps to provide outcomes or guidance to the graph authoring tool. If a Juypter notebook is not already open within the VS Code, Copilot will build a new notebook based on the prompt given. Once Copilot is done, select a kernel to run the notebook. This can be done from the top right of the Notebook: Click on Select Kernel. Click on Microsoft Sentinel. Choose a pool option for the compute cluster. Once a pool is picked, click on the run button next to one of the code cells to boot up the compute pool (this can take up to 5 minutes) Once connected, users can either go through and click the run button next to the code cell to run the code or click the Run All button at the top of the Notebook. For each cell in the Notebook: Cell 2 This section of the notebook is for mporting the sentinel_graph library and configures Spark settings. This is essentially setting up the notebook environment for executing the rest of the code. from sentinel_graph import notebook notebook.requires(sentinel_graph="0.3.8") spark.conf.set("spark.sql.parquet.datetimeRebaseModeInRead", "CORRECTED") Cell 3 This section is performing more Sentinel specific configurations by defining which Sentinel workspace to use, which timerange to use, which tables to use, etc. This is defining which data sources should be considered when building the graph. from pyspark.sql import functions as F from sentinel_lake.providers import MicrosoftSentinelProvider lake_provider = MicrosoftSentinelProvider(spark=spark) LOG_ANALYTICS_WORKSPACE = "Woodgrove-LogAnalyiticsWorkspace" # Auto-detected from the Microsoft Sentinel extension TARGET_USER = "ram723@int.zava-private.com" # Time filter — 7 days for broader blast radius context time_filter = F.col("TimeGenerated") >= F.expr("current_timestamp() - INTERVAL 7 DAYS") # --- IdentityInfo: user profile, roles, group memberships, risk --- df_identity_info = ( lake_provider.read_table("IdentityInfo", LOG_ANALYTICS_WORKSPACE) .filter(time_filter) .filter(F.lower(F.col("AccountUPN")) == TARGET_USER.lower()) ) # --- SigninLogs: interactive sign-ins to resources --- df_signins = ( lake_provider.read_table("SigninLogs", LOG_ANALYTICS_WORKSPACE) .filter(time_filter) .filter( (F.lower(F.col("UserPrincipalName")) == TARGET_USER.lower()) & (F.col("ResultType") == "0") # successful sign-ins ) ) Cell 4 This section is defining and building the nodes that will be used in the graph. The definitions include what events look like, which entities are involved, and how they are considered for each node type. # 1. User node (the target user) user_nodes = ( df_identity_info .select( F.col("AccountUPN"), F.col("AccountDisplayName"), F.col("RiskLevel"), F.col("RiskState"), F.col("AssignedRoles"), F.col("GroupMembership"), F.col("BlastRadius"), F.col("Department"), F.col("JobTitle"), F.col("IsMFARegistered"), F.col("IsAccountEnabled") ) .distinct() .withColumn("AccountUPN", F.lower(F.col("AccountUPN"))) ) Cell 5 This section is building out the schema for the graph. The schema for a graph is taking the columns and details from the tables in cell 3 while also tying them to the nodes and edges built in cell 4. # Build nodes first builder = ( GraphSpecBuilder.start() # === NODES === .add_node("User") .from_dataframe(user_nodes) .with_columns("AccountUPN", "AccountDisplayName", "RiskLevel", "RiskState", "AssignedRoles", "GroupMembership", "BlastRadius", "Department", "JobTitle", "IsMFARegistered", "IsAccountEnabled", key="AccountUPN", display="AccountUPN") # Then add edges and finalise into a GraphSpec spec = ( builder # === EDGES === .add_edge("AccessedInteractive") .from_dataframe(edge_user_resource_interactive) .source(id_column="UserUPN", node_type="User") .target(id_column="ResourceName", node_type="Resource") .with_columns("AppDisplayName", "TimeGenerated", "IPAddress", "ConditionalAccessStatus", "AccessType", "EdgeKey", key="EdgeKey", display="AccessType") Cell 6 This cell will take the schema from cell 5 and will load it into the graph visual builder. This will give a sample of what the graphs made with this Notebook will look like. These samples are fully interactive and will give an example of how it will look within the Defender portal. For example: Please note that the Authoring Agent may provide a different looking schema if following along with this example. The schema above is just meant to provide an example of what one will look like within a Notebook. Cell 7 This cell is taking each of the following steps performed and is going to compile and build the graph based on the data from the Sentinel data lake. This may take a few minutes to perform. With the custom graph built, the next step is to create a Graph Job to save the custom graph in the tenant for persistent use. If necessary, users can go back into the notebook to refine, expand, and improve the custom graph. Publishing graph Publishing a graph is the process of saving the graph in a tenant, allowing for the graph to be scheduled for recurring refreshes or as needed. This process saves the graph to the tenant and enables other SOC members to access this graph from within the Defender portal. To publish a custom graph, this must go through a Graph Job. This option is available within the Notebook experience as a button near the top: Clicking on the Create Scheduled Job button will open a new tab within VS Code with the jobs settings and the option to publish: There are two types of job schedules: On Demand: Saves the custom graph to the tenant and will persist the custom graph for 30 days. After 30 days, the graph will be auto deleted. Scheduled: Saves the custom graph to the tenant and will rebuild with new security telemetry based on a user defined schedule. Once everything is prepped, the custom graph can be published to the tenant by hitting the Submit button. Users can view and monitor the creation progress by finding the graph within the Sentinel extension navigation as it shows the graphs available for the environment: Finding and selecting the custom graph will open up a new tab that shows details around the graph. This includes details around the name, creation status (creating, ready, etc), author, and publishing date. Near the top, there are tabs for Job Details and Graph Query. These options allow the user to review the current Graph Job, make changes to the Graph Job, or query the graph within the notebook. Querying the graph in Defender Once the custom graph has been published and the creation status is Ready, users can query the new graph in the Defender Portal: Expand the Microsoft Sentinel navigation. Select Graphs. Either find the card with the graph title or search for it within the menu. Once found, click Query Graph to open it. The graph will open in the schema view. The schema here is a visual representation of which nodes, edges, and relations are part of the graph. This is what was built in the notebook. To query it, a user can write GQL queries or use ones that are provided. For this example, a query provided in the Getting Started tab will be used. This is a generic query that will show everything in a graph: // Visualize any graph MATCH (x)-[y]->(z) RETURN * LIMIT 100 More focused queries will yield more focused results. For example: MATCH (n_user:User)-[e_ip:SignedInFrom]->(n_ip:IPAddress) MATCH (n_user)-[e_signin:InteractiveSignIn]->(n_app:Application) WHERE n_user.UserPrincipalName = 'ENTERUSERNAMHERE' AND n_ip.IPAddress = 'IPADDRESSHERE' RETURN n_user, e_ip, n_ip, e_signin, n_app MATCH (n_user)-[x]->() MATCH (n_user)-[e_signin:InteractiveSignIn]->(n_app:Application) WHERE n_user.UserPrincipalName = 'ENTERUSERNAMEHERE' RETURN * From here, a user can continue the hunt, remediate the concerns, escalate this for further attention and remediation, or refine the graph as needed. Refining Graphs Throughout the process, the custom graph may need to be updated for various reasons, including: The scope of the hunt/investigation has expanded due to new information or the hypothesis being updated based on findings The original hypothesis of the hunt was incorrect or needs to be changed Important nodes are missing from the graph and need to be added To achieve this, return to VS Code and use the GitHub Copilot chat experience to add new telemetry, nodes, edges, or properties in the existing graph. The below example illustrates adding Azure resources as new assets by prompting the Sentinel graph authoring tool and instructing it on what needs to be added. Running the cells of the Notebook will yield an updated graph that includes the new changes: Graph samples in the Sentinel VS Code extension To help with learning, building, and using Sentinel graph, there are 5 graph samples included in the Sentinel extension within VS Code. These can be found by clicking on the Sentinel extension and looking under Notebook Samples > Graphs. Each graph included contains a Jupyter notebook containing the graph schema and mappings, as well as graph queries which can be run against the graph. These graphs ingest certain security telemetry and expect them to already exist within the Sentinel lake instance that is being used. If needed, the graph mapping can be updated to include/ exclude security telemetry as needed. These graph samples are also located within the Sentinel GitHub repository. Let’s look at one of the sample graphs – Phishing Email Killchain to understand how it can help during a security investigation. Using a graph: phishing email kill chain scenario Phishing is the number one initial access vector, yet investigating a phishing campaign requires correlating data across multiple Sentinel tables: EmailEvents, EmailUrlInfo, UrlClickEvents, EmailAttachmentInfo, DeviceFileEvents, and DeviceProcessEvents. Each table uses a different join key (NetworkMessageId, AccountUpn, SHA256, DeviceName), and analysts must stitch results together manually across several Defender portals. The core question every SOC analyst needs to answer is: “Who received the email, clicked the URL, downloaded the attachment, and executed it on their device?” In KQL, answering this requires 5+ sequential queries and 30–60 minutes of manual correlation. The Phishing Email Kill Chain graph fuses all of these tables into a single connected structure with 10 node types and 12 edge types, making it possible to answer that question in seconds with a single GQL traversal. SOC teams can create this graph in their tenant and start investigating phishing campaigns using graph-powered insights. Investigation with the Phishing Email Killchain graph Multi-hop traversal. The full kill chain from email to endpoint execution is a 4-hop path: Email → Attachment → Process → Device. In KQL, each hop is a separate join with a different key column. In the graph, it’s one MATCH clause. Structural detection. Campaign topology is visible as the graph’s shape — senders fanning out to emails, emails fanning out to users, shared URLs converging into hubs. These patterns are structural properties requiring no aggregation queries. Click-exposure overlay. The graph overlays email delivery and URL click paths in a single view. An analyst instantly sees which users received a phishing email AND clicked the embedded URL — no separate UrlClickEvents join needed. Example queries Below are three queries from the published phishing_email_killchain graph that demonstrate these capabilities. Each query is a single GQL statement that replaces multiple KQL joins. Query 1: Full Kill Chain — Email to Endpoint This query traces the complete attack path: phishing email → malicious attachment → process execution → endpoint device. In KQL, this requires joining 4 tables with different keys and temporal proximity filtering. MATCH (e:Email)-[ha:HasAttachment]->(att:Attachment) -[tp:TriggeredProcess]->(p:Process)-[od:OnDevice]->(d:Device) RETURN e, ha, att, tp, p, od, d LIMIT 10 Figure 1: Two complete kill chains — Invoice_Q3.xlsm → EXCEL.EXE → DESKTOP-FIN01 and DocuSign_Contract.pdf.exe → cmd.exe → DESKTOP-SALES02. Each path is one traversal replacing 4+ KQL joins. Query 2: Campaign Topology — Sender to Email to User to URL This query visualizes the full campaign structure: which senders sent which emails, who received them, and what URLs were embedded. The graph’s fan-out shape immediately reveals the blast radius and shared infrastructure. MATCH (s:Sender)-[se:Sent]->(e:Email)-[re:ReceivedEmail]->(u:User), (e)-[cu:ContainsUrl]->(url:Url) RETURN s, se, e, re, u, cu, url LIMIT 10 Figure 2: Campaign topology — 2 senders, 2 emails fanning out to 9 users and 2 URLs. The shared URL node (c0ntoso-share...) receiving edges from both emails reveals coordinated campaign infrastructure. Query 3: URL Click Exposure — Who Clicked the Phishing Links This query shows which emails contained URLs and which users clicked them. The Email → URL → User click chain is a single traversal that replaces joining EmailUrlInfo with UrlClickEvents. MATCH (e:Email)-[cu:ContainsUrl]->(url:Url)<-[cl:ClickedUrl]-(u:User) RETURN e, cu, url, cl, u LIMIT 10 Figure 3: Click exposure — 3 users clicked phishing URLs from 3 different emails. Each cluster shows Email → URL → User, instantly identifying click-through victims. These are just 3 examples of what is possible when using GQL on a graph. Users can author their own GQL queries to run on this graph to show other possibilities. Additional graph samples As mentioned, the Phishing Email Killchain graph is one of five graph samples that are available today for use within the VS Code Sentinel Extension. The remaining graphs are: Behavioral Attack Chain Ingests data from the SentinelBehaviorInfo, SentinelBehaviorEntities, AlertInfo, AlertEvidence, ThreatIntelIndicators, and BehaviorAnalytics tables to model the relationships between different detections, MITRE tactics/techniques, entities, and threat intel to high different traversals that are difficult to do with just KQL alone. Databricks Outbound Exfiltration Ingests data from the DatabricksNotebook, DatabricksSecrets, DatabricksDBFS, DatabricksClusters, DatabricksJobs, DatabricksSQLPermissions, IdentityInfo, AADUserRiskEvents, and BehaviorAnalytics tables to map Databricks notebook and cluster activities to the identities used in order to enable detections of unusual outbound data movement, privilege escalation, and data exfiltration patterns. DNS C2 Beaconing Ingests data from the DeviceNetworkEvents, DeviceInfo, and ThreatIntelIndicators to model DNS resolution patterns to detect C2 beaconing and other malicious patterns. OAuth Privilege Escalation Ingests data from the EntraServicePrincipals, AADRiskyServicePrincipals, and AADServicePrincipalSignInLogs tables to trace OAuth consent chains, credential abuse, and privilege escalation paths to identify hub users, over-permissions identities, and backdoor patterns that may exist. Closing This blog showcased an example of how a custom graph can be made with data within Microsoft Sentinel data lake and the help of GitHub Copilot, investigating a phishing email kill chain situation, and how to leverage the several graph templates that are provided in Sentinel. Get started today by using one of the template graphs, building your own graph, or by checking out the public documentation for Sentinel graph.

Introducing New Additions to Microsoft Sentinel Normalization and ASIM
TL;DR: New ASIM parsers for Azure Firewall, Key Vault, AWS CloudTrail (EC2, S3, IAM), and 10+ third-party products. Two new schemas — Asset Entities and AI Agent Events. Plus changelogs on GitHub and a heads-up on an upcoming breaking change in ProcessEvent parsers. What's New Security teams deal with logs from dozens of sources, each with its own schema. This painpoint makes it harder to write detections that work everywhere. The Advanced Security Information Model (ASIM) solves this by normalizing logs into a common schema, so a single analytic rule can cover a wide variety of sources without worrying about the source schema. Over the past few months, we have shipped a wave of new parsers, schemas, and improvements to ASIM. Here's everything you need to know. ASIM Parsers Azure Firewall Azure Firewall logs were previously only supported from the AzureDiagnostics table. Now, we support the dedicated resource-specific tables: Table ASIM Schema AZFWDnsQuery DNS AZFWNetworkRule NetworkSession AZFWApplicationRule WebSession Azure Key Vault Logs that are going to both AzureDiagnostics and resource-specific table AZKVAuditLogs are now normalized in the Audit Event schema. Azure Synapse SQL and Azure SQL Database Logs that are going to both AzureDiagnostics and resource-specific table SQLSecurityAuditEvents are now normalized to the Audit Event schema. Azure Traffic Analytics We have added support for the NTANetAnalytics table from Azure Traffic Analytics under the Network Session schema. AWS CloudTrail AWS CloudTrail previously only mapped to the Authentication schema. Now, you can correlate EC2, S3, and IAM activity through ASIM alongside your Azure telemetry: AuditEvent — Normalized EC2 events FileEvent — Normalized S3 events UserManagement — Normalized IAM and Cognito events Additional Parser Support We have also integrated the following third-party sources into ASIM: Authentication — Normalize sign-in and identity events for cross-source threat detection. CheckPoint Smart Defense Cisco IOS Cisco ISE Fortinet FortiGate Okta (OktaSystemLogs) Palo Alto — PAN-OS Palo Alto — Global Protect VMware vCenter Web Session — Normalize proxy and web gateway traffic. Cisco Umbrella Proxy Logs New ASIM Schemas We have created two new schemas to expand support new use cases. Asset Entities — Provides a normalized view of asset inventory data, enabling you to correlate files and assets across detections and investigations. AI Agent Events — Normalizes telemetry from AI-driven workflows and autonomous agents. Other Changes GitHub Changes Changelogs for every ASIM parser have been created to better help you understand updates and bug fixes we have implemented. As an example, here is the change log for the Authentication ASIM unifying parser. View Changelog Breaking Changes While aligning our ProcessEvent parsers to the official documentation, we found a naming inconsistency in the _Im_ProcessCreate function: Documentation specifies the parameter as targetusername_has Deployed parsers used targetusername What we changed: Both parameter names are now accepted. What you need to do: Update your analytic rules and queries to use targetusername_has. The legacy targetusername parameter will be deprecated in Summer 2026. What's Next We are continuing to expand ASIM with new parsers and schema capabilities to make detection authoring and log correlation even more powerful. BlueVoyant is also investing heavily in the ASIM ecosystem, building parsers that enhance detection coverage for their customers. See how they are using ASIM to operationalize detections. Want to get involved? Browse the ASIM parsers on GitHub, file issues, or contribute your own. We'd love to hear your feedback.Microsoft Sentinel data lake FAQ

Can I use the Sentinel data lake? Yes. You must connect Sentinel to the Defender experience before onboarding to the Sentinel data lake. Microsoft Sentinel is generally available in the Microsoft Defender portal, with or without Microsoft Defender XDR or an E5 license. If you have created a log analytics workspace, enabled it for Sentinel and have the right Microsoft Entra roles (e.g. Global Administrator + Subscription Owner, Security Administrator + Sentinel Contributor), you can enable Sentinel in the Defender portal. For more details on how to connect Sentinel to Defender review these sources: Microsoft Sentinel in the Microsoft Defender portal In what regions is Sentinel data lake available? For supported regions see: Geographical availability and data residency in Microsoft Sentinel | Azure Docs. Is there an expected release date for Microsoft Sentinel data lake in GCC, GCC-H, and DoD? While the exact date is not yet finalized, we plan to expand Sentinel data lake to the US Government environments. . How will URBAC and Entra RBAC work together to manage the data lake given there is no centralized model? Entra RBAC will provide broad access to the data lake (URBAC maps the right permissions to specific Entra role holders: GA/SA/SO/GR/SR). URBAC will become a centralized pane for configuring non-global delegated access to the data lake. For today, you will use this for the “default data lake” workspace. In the future, this will be enabled for non-default Sentinel workspaces as well – meaning all workspaces in the data lake can be managed here for data lake RBAC requirements. Azure RBAC on the Log Analytics (LA) workspace in the data lake is respected through URBAC as well today. If you already hold a built-in role like log analytics reader, you will be able to run interactive queries over the tables in that workspace. Or, if you hold log analytics contributor, you can read and manage table data. For more details see: Roles and permissions in the Microsoft Sentinel platform | Microsoft Learn Data ingestion and storage How do I ingest data into the Sentinel data lake? To ingest data into the Sentinel data lake, you can use existing Sentinel data connectors or custom connectors to bring data from Microsoft and third-party sources. Data can be ingested into the analytics tier or the data lake tier. Data ingested into the analytics tier is automatically mirrored to the lake (at no additional cost). Alternatively, data that is not needed in the analytics tier can be ingested directly into the data lake. Data retention is configured directly in table management, for both analytics retention and data lake storage. Note: Certain tables do not support data lake-only ingestion via either API or data connector UI. See here for more information: Custom log tables. What is Microsoft’s guidance on when to use analytics tier vs. the data lake tier? Sentinel data lake offers flexible, built-in data tiering (analytics and data lake tiers) to effectively meet diverse business use cases and achieve cost optimization goals. Analytics tier: Is ideal for high-performance, real-time, end-to-end detections, enrichments, investigation and interactive dashboards. Typically, high-fidelity data from EDRs, email gateways, identity, SaaS and cloud logs, threat intelligence (TI) should be ingested into the analytics tier. Data in the analytics tier is best monitored proactively with scheduled alerts and scheduled analytics to enable security detections Data in this tier is retained at no cost for up to 90 days by default, extendable to 2 years. A copy of the data in this tier is automatically available in the data lake tier at no extra cost, ensuring a unified copy of security data for both tiers. Data lake tier: Is designed for cost-effective, long-term storage. High-volume logs like NetFlow logs, TLS/SSL certificate logs, firewall logs and proxy logs are best suited for data lake tier. Customers can use these logs for historical analysis, compliance and auditing, incident response (IR), forensics over historical data, build tenant baselines, TI matching and then promote resulting insights into the analytics tier. Customers can run full Kusto queries, Spark Notebooks and scheduled jobs over a single copy of their data in the data lake. Customers can also search, enrich and promote data from the data lake tier to the analytics tier for full analytics. For more details see documentation. What does it mean that a copy of all new analytics tier data will be available in the data lake? When Sentinel data lake is enabled, a copy of all new data ingested into the analytics tier is automatically duplicated into the data lake tier. This means customers don’t need to manually configure or manage this process, every new log or telemetry added to the analytics tier becomes instantly available in the data lake. This allows security teams to run advanced analytics, historical investigations, and machine learning models on a single, unified copy of data in the lake, while still using the analytics tier for real-time SOC workflows. It’s a seamless way to support both operational and long-term use cases—without duplicating effort or cost. What is the guidance for customers using data federation capability in Sentinel data lake? Starting April 1, 2026, federate data from Microsoft Fabric, ADLS, and Azure Databricks into Sentinel data lake. Use data federation when data is exploratory, infrequently accessed, or must remain at source due to governance, compliance, sovereignty, or contractual requirements. Ingest data directly into Sentinel to unlock full SIEM capabilities, always-on detections, advanced automation, and AI‑driven defense at scale. This approach lets security teams start where their data already lives — preserving governance, then progressively ingest data into Sentinel for full security value. Is there any cost for retention in the analytics tier? Analytics ingestion includes 90 days of interactive retention, at no additional cost. Simply set analytics retention to 90 days or less. Analytics retention beyond 90 days will incur a retention cost. Data can be retained longer within the data lake by using the “total retention” setting. This allows you to extend retention within the data lake for up to 12 years. While data is retained within the analytics tier, there is no charge for the mirrored data within the lake. Retaining data in the lake beyond the analytics retention period incurs additional storage costs. See documentation for more details: Manage data tiers and retention in Microsoft Sentinel | Microsoft Learn What is the guidance for Microsoft Sentinel Basic and Auxiliary Logs customers? If you previously enabled Basic or Auxiliary Logs plan in Sentinel: You can view Basic Logs in the Defender portal but manage it from the Log Analytics workspace. To manage it in the Defender portal, you must change the plan from Basic to Analytics. Once the table is transitioned to the analytics tier, if desired, it can then be transitioned to the data lake. Existing Auxiliary Log tables will be available in the data lake tier for use once the Sentinel data lake is enabled. Billing for these tables will automatically switch to the Sentinel data lake meters. Microsoft Sentinel customers are recommended to start planning their data management strategy with the data lake. While Basic and Auxiliary Logs are still available, they are not being enhanced further. Sentinel data lake offers more capabilities at a lower price point. Please plan on onboarding your security data to the Sentinel data lake. Azure Monitor customers can continue to use Basic and Auxiliary Logs for observability scenarios. What happens to customers that already have Archive logs enabled? If a customer has already configured tables for Archive retention, existing retention settings will not change and will be automatically inherited by the Sentinel data lake. All data, including existing data in archive retention will be billed using the data lake storage meter, benefiting from 6x data compression. However, the data itself will not move. Existing data in archive will continue to be accessible through Sentinel search and restore experiences: o Data will not be backfilled into the data lake. o Data will be billed using the data lake storage meter. New data ingested after enabling the data lake: o Will be automatically mirrored to the data lake and accessible through data lake explorer. o Data will be billed using the data lake storage meter. Example: If a customer has 12 months of total retention enabled on a table, 2 months after enabling ingestion into the Sentinel data lake, the customer will still have access to 10 months of archived data (through Sentinel search and restore experiences), but access to only 2 months of data in the data lake (since the data lake was enabled). Key considerations for customers that currently have Archive logs enabled: The existing archive will remain, with new data ingested into the data lake going forward; previously stored archive data will not be backfilled into the lake. Archive logs will continue to be accessible via the Search and Restore tab under Sentinel. If analytics and data lake mode are enabled on table, which is the default setting for analytics tables when Sentinel data lake is enabled, all new data will be ingested into the Sentinel data lake. There will only be one storage meter (which is data lake storage) going forward. Archive will continue to be accessible via Search and Restore. If Sentinel data lake-only mode is enabled on table, new data will be ingested only into the data lake; any data that’s not already in the Sentinel data lake won’t be migrated/backfilled. Only data that was previously ingested under the archive plan will be accessible via Search and Restore. What is the guidance for customers using Azure Data Explorer (ADX) alongside Microsoft Sentinel? Some customers might have set up ADX cluster for their DIY lake setup. Customers can choose to continue using that setup and gradually migrate to Sentinel data lake for new data that they want to manage. The lake explorer will support federation with ADX to enable the customers to migrate gradually and simplify their deployment. What happens to the Defender XDR data after enabling Sentinel data lake? By default, Defender XDR tables are available for querying in advanced hunting, with 30 days of analytics tier retention included with the XDR license. To retain data beyond this period, an explicit change to the retention setting is required, either by extending the analytics tier retention or the total retention period. You can extend the retention period of supported Defender XDR tables beyond 30 days and ingest the data into the analytics tier. For more information see Manage XDR data in Microsoft Sentinel. You can also ingest XDR data directly into the data lake tier. See here for more information. A list of XDR advanced hunting tables supported by Sentinel are documented here: Connect Microsoft Defender XDR data to Microsoft Sentinel | Microsoft Learn. KQL queries and jobs Is KQL and Notebook supported over the Sentinel data lake? Yes, via the data lake KQL query experience along with a fully managed Notebook experience which enables spark-based big data analytics over a single copy of all your security data. Customers can run queries across any time range of data in their Sentinel data lake. In the future, this will be extended to enable SQL query over lake as well. Note: Triggering a KQL job directly via an API or Logic App is not yet supported but is on the roadmap. Why are there two different places to run KQL queries in Sentinel experience? Advanced hunting queries both XDR and analytics tables, with compute cost included. Data lake explorer only queries data in the lake and incurs a separate compute cost. Consolidating advanced hunting and KQL explorer user interfaces is on the roadmap. This will provide security analysts a unified query experience across both analytics and data lake tiers. Where is the output from KQL jobs stored? KQL jobs are written into existing or new custom tables in the analytics tier. Is it possible to run KQL queries on multiple data lake tables? Yes, you can run KQL interactive queries and jobs using operators like join or union. Can KQL queries (either interactive or via KQL jobs) join data across multiple workspaces? Security teams can run multi-workspace KQL queries for broader threat correlation Pricing and billing How does a customer pay for Sentinel data lake? Billing is automatically enabled at the time of onboarding based on Azure Subscription and Resource Group selections. Customers are then charged based on the volume of data ingested, retained, and analyzed (e.g. KQL Queries and Jobs). See Sentinel pricing page for more details. 2. What are the pricing components for Sentinel data lake? Sentinel data lake offers a flexible pricing model designed to optimize security coverage and costs. At a high level, pricing is based on the volume of data ingested/processed, the volume of data retained, and the volume of data processed. For specific meter definitions, see documentation. 3. How does the business model for Sentinel SIEM change with the introduction of the data lake? There is no change to existing Sentinel analytics tier ingestion business model. Sentinel data lake has separate meters for ingestion, storage and analytics. 4. What happens to the existing Sentinel SIEM and related Azure Monitor billing meters when a customer onboards to Sentinel data lake? When a customer onboards to the Sentinel data lake, nothing changes with analytic ingestion or retention. Customers using data archive and Auxiliary Logs will automatically transition to the new data lake meters. How does data lake storage affect cost efficiency for high volume data retention? Sentinel data lake offers cost-effective, long-term storage with uniform data compression of 6:1 across all data sources, applicable only to data lake storage. Example: For 600GB of data stored, you are only billed for 100GB compressed data. This approach allows organizations to retain greater volumes of security data over extended periods cost-effectively, thereby reducing security risks without compromising their overall security posture. here How “Data Processing” billed? To support the ingestion and standardization of diverse data sources, the Data Processing feature applies a $0.10 per GB (US East) charge for all data ingested into the data lake. This feature enables a broad array of transformations like redaction, splitting, filtering and normalization. The data processing charge is applied per GB of uncompressed data Note: For regional pricing, please refer to the “Data processing” meter within the Microsoft Sentinel Pricing official documentation. Does “Data processing” meter apply to analytics tier data mirrored in the data lake? No. Data processing charge will not be applied to mirrored data. Data mirrored from the analytic tier is not subject to either data ingestion or processing charges. How is retention billed for tables that use data lake-only ingestion & retention? Sentinel data lake decouples ingestion, storage, and analytics meters. Customers have the flexibility to pay based on how data is retained and used. For tables that use data lake‑only ingestion, there is no included free retention—unlike the analytics tier, which includes 90 days of analytics retention. Retention charges begin immediately once data is stored in the data lake. Data lake storage billing is based on compressed data size rather than raw ingested volume, which significantly reduces storage costs and delivers lower overall retention spend for customers. Does data federation incur charges? Data federation does not generate any ingestion or storage fees in Sentinel data lake. Customers are billed only when they run analytics or queries on federated data, with charges based on Sentinel data lake compute and analytics meters. This means customers pay solely for actual data usage, not mere connectivity. How do I understand Sentinel data lake costs? Sentinel data lake costs driven by three primary factors: how much data is ingested, how long that data is retained, and how the data is used. Customers can flexibly choose to ingest data into the analytics tier or data lake tier, and these architectural choices directly impact cost. For example, data can be ingested into the analytics tier—where commitment tiers help optimize costs for high data volumes—or ingested data directly into the Sentinel data lake for lower‑cost ingestion, storage, and on‑demand analysis. Customers are encouraged to work with their Microsoft account team to obtain an accurate cost estimate tailored to their environment. See Sentinel pricing page to understand Sentinel pricing. How do I manage Sentinel data lake costs? Built-in cost management experiences help customers with cost predictability, billing transparency, and operational efficiency. Reports provide customers with insights into usage trends over time, enabling them to identify cost drivers and optimize data retention and processing strategies. Set usage-based alerts on specific meters to monitor and control costs. For example, receive alerts when query or notebook usage passes set limits, helping avoid unexpected expenses and manage budgets. See our Sentinel cost management documentation to learn more. If I’m an Auxiliary Logs customer, how will onboarding to the Sentinel data lake affect my billing? Once a workspace is onboarded to Sentinel data lake, all Auxiliary Logs meters will be replaced by new data lake meters. Do we charge for data lake ingestion and storage for graph experiences? Microsoft Sentinel graph-based experiences are included as part of the existing Defender and Purview licenses. However, Sentinel graph requires Sentinel data lake and specific data sources to build the underlying graph. Enabling these data sources will incur ingestion and data lake storage costs. Note: For Sentinel SIEM customers, most required data sources are free for analytics ingestion. Non-entitled sources such as Microsoft Entra ID logs will incur ingestion and data lake storage costs. How is Entra asset data and ARG data billed? Data lake ingestion charges of $0.05 per GB (US EAST) will apply to Entra asset data and ARG data. Note: This was previously not billed during public preview and is billed since data lake GA. To learn more, see: https://learn.microsoft.com/azure/sentinel/datalake/enable-data-connectors When a customer activates Sentinel data lake, what happens to tables with archive logs enabled? To simplify billing, once the data lake is enabled, all archive data will be billed using the data lake storage meter. This provides consistent long-term retention billing and includes automatic 6x data compression. For most customers, this change results in lower long‑term retention costs. However, customers who previously had discounted archive retention pricing will not automatically receive the same discounts on the new data lake storage meters. In these cases, customers should engage their Microsoft account team to review pricing implications before enabling the Sentinel data lake.

On 29 April 2026, malicious versions of multiple SAP ecosystem npm packages were briefly published, creating a supply-chain exposure for SAP Cloud Application Programming (CAP) development environments and CI/CD pipelines. For a brief window that morning, affected developers have executed a credential-stealing payload on a workstation or, in higher-impact cases, within a CI/CD pipeline. SAP developers don't usually think of themselves as a juicy npm target. CAP, BTP, Fiori - that's enterprise turf, not crypto-stealer type territory – Until it is. Join me for the ride. See our latest click-video for an even more dynamic experience of SAP compromises. Affected packages and scope Four official npm packages from the SAP development ecosystem were published in malicious versions that day. Security researchers are calling the campaign "Mini Shai-Hulud" - the little cousin of the worm family that has been chewing its way through open-source registries for months. So, the "mini" part is a generous description in my opinion. Shai-Hulud has wriggled directly into the SAP supply chain, and that detail alone deserves a pause... SAP CAP is now interesting enough to have become a target. Four packages, all wearing legitimate SAP branding, all quietly swapped for evil twins: @cap-js/sqlite v2.2.2 @cap-js/postgres v2.2.2 @cap-js/db-service v2.10.1 mbt v1.2.48 These packages are not peripheral dependencies. The @cap-js/* modules are part of the SAP CAP Model used across custom development on SAP BTP, while mbt is the Cloud MTA Build Tool commonly embedded in CI/CD workflows that package and deploy Multi-Target Applications to BTP and on-premises environments. At roughly 930,000 weekly downloads, the combined exposure created meaningful downstream attack surface. The good news: SAP spotted the compromise fast, yanked the bad versions, and shipped clean replacements. The official guidance lives in SAP Security Note 3747787 - which carries the list of indicators of compromise, file hashes, and mitigation steps. Enough theory and evidence talk! Now, SHOW ME the detection! When the worm stirs beneath the sand, weak defenses vanish first. Observed telemetry in Microsoft Security products See below excerpt of Microsoft Defender for Endpoint from a compromised developer machine. The worm was neutralized immediately. Check the detection time (same day of release): Windows Defender AV detected malware ToString: DefenderDetection: File: /Users/User***/Projects/dara-api-manager-ui/node_modules/mbt/File***.js, Sha256: *** [Trojan:JS/SPchnStlr.BB], BlockingStatus: Prevented, BlockingStatusPriority: 900 DetectionTime: 2026-04-29 11:52:11Z DetectorName: Microsoft.Cyber.ObservationDetectors.DefenderConcreteDetector Observations (2): DefenderObservation Description: Defender detected and quarantined 'Trojan:JS/SPchnStlr.BB' in file 'File***.js' ThreatCategory = Trojan, ThreatFamily = SPchnStlr, How the Threat Actors Operationalized the Stolen Data The compromise allowed harvesting GitHub tokens, AWS/Azure/GCP secrets, npm credentials, Kubernetes config, SSH keys, .npmrc and .git-credentials files, and CI/CD environment variables. The hackers created a public GitHub repository on the victim’s own account, tagged with the description “A Mini Shai-Hulud has Appeared“ to exfiltrate their reaping. Within hours, more than a thousand such repositories were visible in public GitHub search. For additional views on the topic check out the blogs of our Sentinel for SAP partners: Onapsis, Pathlock, and SecurityBridge. Containment and Impact Reduction If you were not as lucky as the developer using Defender for Endpoint and VS Code, you need end to end monitoring of your landscape in and around SAP. Once the worm is loose with cloud tokens it may appear in various unexpected places. Microsoft Sentinel Solution for SAP covers your ERP crown jewels, your SAP BTP landscape and allows informed correlation with the rest of your IT estate. Microsoft’s correlation engine: ensures traceability automatic attack disruption and just-in-time hardening of potential attack paths. Developers using the cloud-based IDE SAP Business Application Studio are out of reach by Defender for Endpoint but profit from threat monitoring through Sentinel for SAP BTP integrating SAP BTP’s malware scanner the same way. See this in action in this click-video and in below screenshot. SOC analysts get actionable insights and tailored guidance from Security Copilot once SAP BTP signals are added to the Microsoft incident graph - no matter where the threat involving SAP originates from.

Welcome to the May edition of What's new in Microsoft Sentinel. This month’s updates focus on unified role-based access control (RBAC), ecosystem breadth, AI-agent security, and high-assurance identity. RBAC and row-level scoping are now generally available, giving security teams a single, granular permissions model across Sentinel and the Microsoft Defender portal and enabling multi-team SOC collaboration. The Sentinel connector catalog has passed 400 connectors, expanding coverage across Microsoft and third-party data sources and helping customers and partners onboard new data faster with the Codeless Connector Framework (CCF). The Agent 365 connector, now in public preview, brings AI agent telemetry into Sentinel data lake as first-class standardized signals so you can monitor agent behavior alongside identity, endpoint, and cloud activity. Finally, Entra Verified ID partner integrations in Microsoft Security Store are now generally available, delivering high‑assurance identity verification that makes account recovery after compromise far safer and significantly reduces the risk of re‑compromise. Read on for the full list of updates across Sentinel in May. Sentinel innovations: Sentinel SIEM Sentinel data lake Microsoft Security Store Sentinel SIEM Unified role-based access controls and row level scoping [Generally available] Sentinel now delivers general availability of two powerful access management capabilities: Unified RBAC and row-level data scoping. Together, these innovations provide a consistent, end-to-end model for controlling who can access data and what actions they can take — extending unified permissions management across the Defender portal while enabling granular, row-level visibility within a single Sentinel workspace. With Unified RBAC, organizations can simplify and centralize permissions across security workloads, reducing operational overhead, while row-level scoping enables secure collaboration across multiple teams by ensuring users only see data aligned to their role or scope. This milestone unlocks more scalable, multi-team SOC operations without the need for workspace segmentation, helping us to advance toward fully unified, granular access control across Microsoft Security. Tenant groups [Public preview] Managing security across multiple tenants just got simpler. Tenant Groups in the Microsoft Defender multi-tenant portal (MTO) give managed security service providers (MSSPs), cloud service partners (CSPs), and multi-tenant security teams a flexible way to organize tenants into logical groupings such as customer segment, geography, or operational priority, and instantly switch views with a single click. This streamlined experience reduces noise, improves investigation focus, and aligns to how teams actually work, all while respecting existing permissions and access controls. Learn more. Out-of-the-box integrations for Sentinel automation [Public preview] Out-of-the-box (OOTB) integrations for Sentinel automation brings a centralized catalog to easily discover, configure, and manage both Microsoft and third-party integrations. With simple, authentication-based setup, users can quickly add integrations and seamlessly incorporate them into playbooks. The experience places OOTB and custom integrations side by side, with enhanced with smart search, recommendations, and duplicate prevention to streamline automation workflows end to end. Learn more. UEBA enhancements [Public preview] Microsoft Sentinel UEBA continues to evolve with improvements that simplify management and expand detection coverage. A dedicated UEBA tab view in the Sentinel settings page consolidates UEBA and behaviors settings, making configuration easier to find and manage. Learn more. UEBA insights and anomalies now support the OktaV2_CL table alongside the existing Okta_CL table, extending anomalous activity and anomalous MFA failures detections to customers using the newer Okta connector format, without requiring new anomaly types. Learn more. UEBA extends GCP Audit Logs coverage with five anomaly detections for login activity, privileged actions, resource deployments, secret/KMS key access, and infrastructure usage. Learn more. Together, these updates make UEBA easier to operate while extending its visibility into identity and behavior signals from additional cloud and identity providers. Read the latest blog from the Microsoft Defender Research Team to learn more about Microsoft Sentinel UEBA and binary feature stacking, which uses clear binary signals to help establish behavioral context and inform investigation and detection decisions. Threat Intelligence – TAXII Export connector [Generally available] Sentinel supports threat intelligence export through the built-in Threat Intelligence – Trusted Automated Exchange of Intelligence Information (TAXII) Export connector, giving customers a standards-based way to share curated Structured Threat Information Expression (STIX) objects with supported TAXII 2.1 platforms. Configured from the Defender portal, the connector handles destination setup and intelligence delivery to external platforms. The capability supports cross-organization intelligence sharing for collective defense and centralized management in multi-tenant environments, with use cases across government, critical infrastructure, and large distributed organizations. Additional enhancements are planned, including more export options and expanded destination support. Learn more. Decision-stage resources for SIEM migration to Sentinel The AI-powered SIEM migration experience helps teams analyze detections, identify required data sources and connectors, and plan a phased move to Sentinel. But, customers still need help turning that analysis into a clear decision. To support that step, we’re introducing two new customer-facing resources: the Sentinel SIEM Migration Decision and Planning Guide, which explains the migration journey, outputs, and decision checkpoints before execution, and the Decision-Stage Customer FAQ, which answers common questions around disruption, cost, dual running, detection coverage, and delivery support. Together, these resources help make migration conversations more concrete and move teams more quickly from evaluation to a clearer, lower-risk next step. Learn more: Read the blog: AI-powered SIEM migration experience announcement Download the guide: Decision and planning guide Download the FAQ: Decision-stage customer FAQ Learn more: SIEM migration experience documentation Register for live AMA (Jun 23 at 9am PT): Live Microsoft Tech Community AMA on SIEM migration Sentinel data lake 400+ Sentinel data connectors The Sentinel connector catalog now includes 400+ connectors, providing broad, ready-to-deploy coverage across Microsoft and third-party data sources. Customers can flexibly ingest security data into Microsoft Sentinel analytics tier or the data lake tier. The Codeless Connector Framework (CCF) and VS code-based connector builder agent enables partners and customers to onboard new data sources faster and scale the catalog. Discover connectors in the Sentinel Content hub within the Defender portal or build custom connectors when needed. Learn more. Agent 365 connector [Public preview] Agent 365 connector streams AI agent telemetry from Agent 365 into Sentinel data lake, giving SOC teams visibility into agent behavior alongside identity, endpoint, and cloud signals. With the Agent 365 connector in place, Sentinel data lake becomes the system of record for agent security, turning activity such as data exposure or access drift into first-class security signals that analysts can correlate, hunt across, and investigate. Telemetry is normalized and to mapped to standard Advanced Security Information Model (ASIM) schemas, ready for analytics and detections, and end-to-end investigations can run through KQL, graph, and MCP-powered workflows. Install the connector with a single click from Sentinel Content Hub in the Defender portal. Learn more. CCF support for Azure Blob Storage [Public preview] Sentinel Codeless Connector Framework (CCF) supports Azure Blob Storage as a data source, providing an ingestion pattern designed for high-volume security data. Partners and customers can build CCF connectors that read from Blob Storage through a durable architecture that buffers spikes, handles backpressure, and reduces data loss risk during outages or throttling, making ingestion more reliable for variable or distributed pipelines. The pattern broadens compatibility with partners already streaming logs to Azure as part of their audit data delivery, with Cloudflare and Netskope as early adopters. App Assure further provides engineering-backed support for designing, validating, and remediating the Azure Blob Storage CCF connector integration. Learn more. Data filtering and splitting [Generally available] At RSAC, we announced built‑in filtering and splitting capabilities in Microsoft Sentinel, which is now generally available. As security teams ingest more data, it is important to optimize security data pipeline by controlling what data is ingested and in which tier. With filtering and splitting natively integrated into the Defender portal, security teams can shape data before it reaches Sentinel, without switching tools or managing custom JSON files. Using simple KQL‑based transformations directly in the UI, you can filter low‑value events and intelligently route data, making ingestion optimization faster, more intuitive, and easier to manage at scale. Filtering at ingest time allows you to remove low‑value or benign events to reduce noise, lower unnecessary processing, and ensure high‑signal data drives detections and investigations. Splitting enables intelligent routing of data between the analytics tier and the data lake tier based on relevance and usage. Together, these capabilities help you balance cost and performance while scaling data ingestion sustainably as your digital estate grows. Learn more. Transition your Sentinel connectors to the Codeless Connector Framework (CCF) [Action required] Azure has announced that the legacy Azure Data Collection API will be deprecated on September 14, 2026. Sentinel recommends customers review existing connectors and upgrade to the latest Codeless Connector Framework (CCF) versions to ensure continued access to the newest Sentinel capabilities. CCF delivers a fully managed SaaS experience with built-in health monitoring, centralized credential management, and improved performance. This enables partners and customers to onboard new data sources faster and at scale. Microsoft Security Store Entra Verified ID partner integrations via Security Store [Generally available] Security Store helps organizations secure one of the most critical steps in incident response: safe account recovery after compromise. Once a SOC team detects and contains a potential account takeover (ATO), restoring access requires high confidence that the user is legitimate. Through partner integrations with IDEMIA, AU10TIX, CLEAR, 1Kosmos, and WhoAmI, customers can extend Entra Verified ID with high-assurance identity verification (such as document and biometric checks) to validate users during recovery, onboarding, or helpdesk workflows. This helps replace weaker fallback methods that attackers often exploit, enabling SOC and IT teams to safely restore access while reducing risk of re-compromise. Learn more. Purview Data Security Triage Agent in Defender [Public preview] Security Store powers how customers discover and activate data security agents across Defender and Microsoft Purview, starting with the Data Security Triage Agent. This capability delivers AI-generated summaries and prioritization of Data Loss Prevention (DLP) alerts directly into Defender XDR, helping security teams reduce noise and focus on the incidents that matter most. By unifying discovery and activation through Security Store, customers can deploy data security agents in fewer steps and enable more integrated workflows across threat and data protection surfaces.

We’ll see you in the next edition!Introducing the next generation of SOC automation: Sentinel playbook generator
Security teams today operate under constant pressure. They are expected to respond faster, automate more, and do so without sacrificing precision. Traditional security orchestration, automation and response (SOAR) approaches have helped, but they still rely heavily on rigid templates, limited action libraries, and workflows stretched across multiple portals. Building and maintaining automation is often slow and constrained at exactly the time organizations need more flexibility. Something needs to change – and with the introduction of AI and coding models the future of automation is going to look very different than it is today. Today, we’re introducing the Microsoft Sentinel playbook generator (now Generally Available), a new way to design code-based playbooks using natural language. With the introduction of generative AI and coding models, coding itself is becoming democratized, and we are excited to bring these new capabilities into our experience. This release represents the first milestone in our next‑generation security automation journey. The playbook generator allows users to design and generate fully functional playbooks simply by describing what they need. The tool generates a Python playbook with documentation and a visual flowchart, streamlining workflows from creation to execution for greater efficiency. This approach is highly flexible, allowing users to automate tasks like team notifications, ticket updates, data enrichment, or incident response across Microsoft and third-party tools. By defining an Integration Profile (base URL, authentication, credentials), the playbook generator can create API calls dynamically without needing predefined connectors. The system also identifies missing integrations and guides users to add them from the Automation tab or within the authoring page Users especially value this capability, allowing for more advanced automations. Playbook creation starts by outlining the workflow. The playbook generator asks questions, proposes a plan, then generates code and documentation once approved. Users can validate playbooks with real alerts and refine code anytime through chat instructions or manual edits. This approach combines the speed of natural language with transparent code, enabling engineers to automate efficiently without sacrificing control or flexibility. Preview customers report that the playbook generator speeds up automation development, simplifies automations for teams, and enables flexible workflow customization without reliance on templates. The playbook generator focuses on fast, intuitive, natural‑language‑driven automation creation, supported by a powerful coding foundation. It aligns with how security teams want to work: flexible, integrated, and deeply customizable. We’re excited to see how customers will use this capability to simplify operations, eliminate repetitive work, and automate tasks that previously demanded deep engineering effort. This marks the start of a new chapter, as AI continues to evolve and reshape what’s possible in security automation. How to get started With just a few prerequisites in place, you can begin creating code‑based automations through natural‑language conversations, directly inside the Microsoft Defender portal. Here’s a quick guide to help you move from first steps to your first generated playbook: 1. Make sure the prerequisites are in place Before you open your first chat in the playbook generator, the AI coding agent behind the playbook generator, confirm that your environment is ready: Security Copilot enabled: Your tenant must have a Security Copilot workspace, configured to use a Europe or US-based capacity. Sentinel workspace in the Defender portal: Ensure your Microsoft Sentinel workspace is onboarded to the Microsoft Defender portal. 2. Ensure you have the right permissions To build and deploy generated playbooks, make sure you have the same permissions required to author Automation Rules—the Microsoft Sentinel Contributor role on the relevant workspaces or resource groups. 3. Configure your integration profiles Integration profiles allow the playbook generator to create and execute any dynamic API calls—one of the most powerful capabilities of this new system. Before you create your first playbook: Go to Automation → Integration Profiles in the Defender portal. Create a Graph API Integration Create Integration to the services you want to have in the playbook (Microsoft Graph, ticketing tools, communication systems, third‑party providers, or others). Provide the base URL, authentication method, and required credentials. 4. Create your first generated playbook From the Automation tab: Select Create → Generated Playbook. Give your playbook a name. 3. The embedded Visual Studio Code window opens— Start in plan mode by simply describing what you want your automation to do. Be explicit about: What data to extract What actions to perform Any conditions or branches Example prompt you can use: “Based on the alert, extract the user principal name, check if the account exists in Entra ID, and if it does, disable the account, create a ticket in ServiceNow, and post a message to the security team channel.” The playbook generator will guide the process, ask clarifying questions, propose a plan, and then—once approved—switch to Act mode to generate the full Python playbook, documentation with a visual flow diagram, and tests. Completing your first playbook marks the beginning of a more intuitive, responsive, and intelligent automation experience—one where your expertise and AI work side by side to transform how your SOC operates. This is more than a new tool; it’s a foundation that will continue to evolve, adapt, and empower defenders as security automation enters its next era.

*Please note that this connector is now in GA status as of March, 2026* We are happy to announce a new data connector that is available to the public: the Microsoft Copilot data connector for Microsoft Sentinel. The new Microsoft Copilot data connector will allow for audit logs and activities generated by different offerings of Copilot to be ingested into Microsoft Sentinel and Microsoft Sentinel data lake. This allows for Copilot activities to be leveraged within Microsoft Sentinel features such as analytic rules/custom detections, Workbooks, automation, and more. This also allows for Copilot data to be sent to Sentinel data lake, which opens the possibilities for integrations with custom graphs, MCP server, and more while offering lower cost ingestion and longer retention as needed. Eligibility for the Connector The connector is available for all customers within Microsoft Sentinel, but will only ingest data for environments that have access to Copilot licenses and SCUs as the activities rely on Copilot being used. These logs are available via the Purview Unified Audit Log (UAL) feed, which is available and enabled for all users by default. A big value of this new connector is that it eliminates the need for users to go to the Purview Portal in order to see these activities, as they are proactively brought into the workspace, enabling SOCs to generate detections and proactively threat hunt on this information. Note: This data connector is a single-tenant connector, meaning that it will ingest the data for the entire tenant that it resides in. This connector is not designed to handle multi-tenant configurations. What’s Included in the Connector The following are record types from Office 365 Management API that will be supported as part of this connector: 261 CopilotInteraction 310 CreateCopilotPlugin 311 UpdateCopilotPlugin 312 DeleteCopilotPlugin 313 EnableCopilotPlugin 314 DisableCopilotPlugin 315 CreateCopilotWorkspace 316 UpdateCopilotWorkspace 317 DeleteCopilotWorkspace 318 EnableCopilotWorkspace 319 DisableCopilotWorkspace 320 CreateCopilotPromptBook 321 UpdateCopilotPromptBook 322 DeleteCopilotPromptBook 323 EnableCopilotPromptBook 324 DisableCopilotPromptBook 325 UpdateCopilotSettings 334 TeamCopilotInteraction 363 Microsoft365CopilotScheduledPrompt 371 OutlookCopilotAutomation 389 CopilotForSecurityTrigger 390 CopilotAgentManagement These are great options for monitoring users who have permission to make changes to Copilot across the environment. This data can assist with identifying if there are anomalous interactions taking place between users and Copilot, unauthorized attempts of access, or malicious prompt usage. How to Deploy the Connector The connector is available via the Microsoft Sentinel Content Hub and can be installed today. To find the connector: Within the Defender Portal, expand the Microsoft Sentinel navigation in the left menu. Expand Configuration and select Content Hub. Within the search bar, search for “Copilot”. Click on the solution that appears and click Install. Once the solution is installed, the connector can be configured by clicking on the connector within the solution and selecting Open Connector Page. To enable the connector, the user will need either Global Administrator or Security Administrator on the tenant. Once the connector is enabled, the data will be sent to the table named CopilotActivity. Note: Data ingestion costs apply when using this data connector. Pricing will be based on the settings for the Microsoft Sentinel workspace or at the Microsoft Sentinel data lake tier pricing.

Agent 365 connector: Monitor, hunt, and investigate AI agent activity in Microsoft Sentinel
As enterprises scale the use of AI agents, SOC teams need visibility into AI agent behavior. The Agent 365 connector, now in public preview, streams rich agent telemetry from Agent 365 into Microsoft Sentinel data lake. Agent activity, such as agent data exposure or access drift, is surfaced alongside other security data, giving SOC teams a unified view across digital environments. AI Agent actions are correlated with agent identity, endpoint, and cloud signals, enabling analysts to run end‑to‑end investigations using KQL, graph, and MCP-powered workflows. Why this matters for organizations By centralizing security and AI agent telemetry in Sentinel data lake, organizations establish a unified control plane for securing AI agents. This enables security teams to analyze agent activity in context with broader signals and investigate using familiar Sentinel tools. This unlocks the ability for SOCs to detect risky or anomalous agent behavior early, understand impact quickly, and respond with speed and confidence. As AI agents take on real operational responsibility, this level of visibility is critical to prevent blind spots, reduce risk, and ensure agents operate safely at enterprise scale. End‑to‑end visibility into AI agent behavior: A centralized view of AI agent behavior allows AI agents to be treated as first-class entities alongside users, identities, endpoints, and workloads. Advanced hunting with KQL: Hunt using KQL to proactively uncover unusual AI agent execution patterns, sensitive actions, or activity without clear human context. These hunts help surface potential risk early using the same workflows already used for other security data. Analyzing blast radius and impact with Sentinel graph: Security teams can correlate AI agent activity with identities, endpoints, and cloud resources to understand blast radius and potential impact during an investigation. By pivoting across related entities in Sentinel, analysts can assess how agent actions connect to the broader environment and support deeper, end‑to‑end investigations. Querying agent data through MCP: Use MCP to surface agent observability data through AI assistants, letting analysts pull agent telemetry into investigation workflows alongside other Sentinel data. Agent 365 connector key capabilities Install the Agent 365 connector with a single click using Sentinel Content Hub in the Defender portal. Once enabled, two capabilities come online automatically: Unified agent telemetry across Agent 365 agent experiences: Rich Agent 365 agent telemetry streams into Sentinel data lake, ready to analyze alongside identity, endpoint, and cloud signals using familiar SOC workflows. ASIM unified schema for AI agent observability: Agent 365 agent observability data is normalized into an ASIM-aligned schema so it is consistent, queryable, and ready for analytics and detections. With the connector in place, Sentinel data lake becomes the system of record and the control plane for Agent 365 agent security—turning agent behavior into first-class security signals across SecOps workflows like hunting, investigation, detection engineering, and response. Use cases Prevent sensitive data exposure from misconfigured agents When an AI agent is granted broader access than intended, a crafted prompt could override safeguards and expose confidential data. With agent telemetry, security teams can trace the full execution path—from prompt to tools to data access—to quickly identify the root cause and contain the exposure. Detect and control agent access drift over time As agents take on new tasks, their permissions can expand beyond the original scope, often without clear visibility. Agent telemetry enables continuous behavioral baselining, making it easier to spot abnormal access patterns early and prevent privilege misuse before it escalates. Uncover hidden lateral movement across agent workflows Agents often collaborate and delegate tasks across systems, creating complex chains of execution that are difficult to track. Agent telemetry provides visibility into these interactions, mapping delegation paths and helping teams understand and limit the potential blast radius. Defend against prompt injection and manipulation attacks Attackers can craft prompts to override agent instructions and manipulate behavior. By capturing prompts and reasoning flows, agent telemetry enables detection of these attacks and provides the context needed to investigate and remediate quickly. Accelerate SOC investigations with end-to-end visibility When an agent is involved in a security alert, understanding its actions can be challenging. Agent telemetry correlates prompts, identities, tools, and data access into a unified timeline, giving SOC teams the clarity needed to investigate faster and respond with confidence. Strengthen governance and compliance for AI agents Organizations need visibility into what agents exist and what data they can access. Agent telemetry provides a comprehensive audit trail of agent activity and access patterns, supporting compliance reporting and policy enforcement. Enable proactive threat hunting on agent behavior Security teams need to stay ahead of emerging risks as agent usage grows. Agent telemetry enables advanced hunting across agent activity, helping detect anomalies, uncover patterns, and identify threats before they impact the organization. Get started with Agent 365 connector Getting started is straightforward. In the Microsoft Defender portal, navigate to Microsoft Sentinel Open Content hub and search for Agent 365 Install the Agent 365 Connector (if not already installed) Open the connector page and select Connect to begin ingestion Once connected, AI agent telemetry starts flowing into Sentinel, ready for hunting, investigation, and response.
