Crawl, Walk, Run: A Practitioner's Guide to AI Maturity in the SOC
Every security operations center is being told to adopt AI. Vendors promise autonomous threat detection, instant incident response, and the end of alert fatigue. The reality is messier. Most SOC teams are still figuring out where AI fits into their existing workflows, and jumping straight to autonomous agents without building foundational trust is a recipe for expensive failure. The Crawl, Walk, Run framework offers a more honest path. It's not a new concept. Cloud migration teams, DevOps organizations, and Zero Trust programs have used it for years. But it maps remarkably well to how security teams should adopt AI. Each phase builds organizational trust, governance maturity, and technical capability that the next phase depends on. Skip a phase and the risk compounds. This guide is written for SOC leaders and practitioners who want a practical, phased approach to AI adoption, not a vendor pitch.Accelerate connectors development using AI agent in Microsoft Sentinel
Today, we’re excited to announce the public preview of a Sentinel connector builder agent, via VS code extension, that helps developers build Microsoft Sentinel codeless connectors faster with low-code and AI-assisted prompts. This new capability brings guided workflows directly into the tooling developers already use, helping accelerate time to value as the Sentinel ecosystem continues to grow. Learn more at Create custom connectors using Sentinel connector AI agent Why this matters As the Microsoft Sentinel ecosystem continues to expand, developers are increasingly tasked with delivering high‑quality, production‑ready connectors at a faster pace, often while working across different cloud platforms and development environments. Building these integrations involves coordinating schemas, configuration artifacts, Azure deployment concepts, and validation steps that provide flexibility and control, but can span multiple tools and workflows. As connector development scales across more partners and scenarios, there is a clear opportunity to better integrate these capabilities into the developer environments teams already rely on. The new Sentinel connector builder agent, using GitHub Copilot in the Sentinel VS code extension, brings more of the connector development lifecycle -- authoring, validation, testing, and deployment into a single, cohesive workflow. By consolidating these common steps, it helps developers move more easily from design to validation and deployment without disrupting established processes. A guided, AI‑assisted workflow inside VS Code The Sentinel connector builder agent for Visual Studio Code is designed to help developers move from API documentation to a working codeless connector more efficiently. The experience begins with an ISVs API documentation. Using GitHub Copilot chat inside VS Code, developers can describe the connector they want to build and point the extension to their API docs, either by URL or inline content. From there, the AI‑guided workflow reads and extracts the relevant details needed to begin building the connector. Open the VS Code chat and set the chat to Agent mode. Prompt the agent using sentinel. When prompted, select /create-connector and select any supported API. For example in Contoso API, enter the prompt as: @sentinel /create-connector Create a connector for Contoso. Here are the API docs: https://contoso-security-api.azurewebsites.net/v0101/api-doc Next, the agent generates the required artifacts such as polling configurations, data collection rules (DCRs), table schemas, and connector definitions, using guided prompts with built‑in validation. This step‑by‑step experience helps ensure configurations remain consistent and aligned as they’re created. Note: During agent evaluation, select Allow responses once to approve changes, or select the option Bypass Approvals in the chat. It might take up to several minutes for the evaluations to finish. As the connector takes shape, developers can validate and test configurations directly within VS Code, including testing API interactions before deployment. Validation of the API data source and polling configuration are surfaced in context, supporting faster iteration without leaving the development environment. When ready, connectors can be deployed directly from VS Code to accessible Microsoft Sentinel workspaces, streamlining the path from development to deployment without requiring manual navigation of the Azure portal. Key capabilities The VS Code connector builder experience includes: AI‑guided connector creation to generate codeless connectors from API documentation using natural language prompts. Support for common authentication methods, including Basic authentication, OAuth 2.0, and API keys. Automated validation to check schemas, cross‑file consistency, and configuration correctness as you build. Built‑in testing to validate polling configurations and API interactions before deployment. One‑click deployment that allows publishing connectors directly to accessible Microsoft Sentinel workspaces from within VS Code. Together, these capabilities support a more efficient path from API documentation to a working Microsoft Sentinel connector. Testimonials As partners begin using the Sentinel connector builder agent, feedback from the community will help shape future enhancements and refinements. Here is what some of our early adopters have to say about the experience: “The connector builder agent accelerated our initial exploration of the codeless connector framework and helped guide our connector design decisions.” -- Rodrigo Rodrigues, Technology Alliance Director “The connector builder agent helped us quickly explore and validate connector options on the codeless connector framework while developing our Sentinel integration.” --Chris Nicosia, Head of Cloud and Tech Partnerships Start building This public preview represents an important step toward simplifying how ISVs build and maintain integrations with Microsoft Sentinel. If you’re ready to get started, the Sentinel connector builder agent is available in public preview for all participants. In the unlikely event that an ISV encounters any issues in building or updating a CCF connector, App Assure is here to help. Reach out to us here.Become a Microsoft Defender for Cloud Ninja

Reviewer: Tom Janetscheck, Senior PMKerberos and the End of RC4: Protocol Hardening and Preparing for CVE‑2026‑20833
CVE-2026-20833 addresses the continued use of the RC4‑HMAC algorithm within the Kerberos protocol in Active Directory environments. Although RC4 has been retained for many years for compatibility with legacy systems, it is now considered cryptographically weak and unsuitable for modern authentication scenarios. As part of the security evolution of Kerberos, Microsoft has initiated a process of progressive protocol hardening, whose objective is to eliminate RC4 as an implicit fallback, establishing AES128 and AES256 as the default and recommended algorithms. This change should not be treated as optional or merely preventive. It represents a structural change in Kerberos behavior that will be progressively enforced through Windows security updates, culminating in a model where RC4 will no longer be implicitly accepted by the KDC. If Active Directory environments maintain service accounts, applications, or systems dependent on RC4, authentication failures may occur after the application of the updates planned for 2026, especially during the enforcement phases introduced starting in April and finalized in July 2026. For this reason, it is essential that organizations proactively identify and eliminate RC4 dependencies, ensuring that accounts, services, and applications are properly configured to use AES128 or AES256 before the definitive changes to Kerberos protocol behavior take effect. Official Microsoft References CVE-2026-25177 - Security Update Guide - Microsoft - Active Directory Domain Services Elevation of Privilege Vulnerability Microsoft Support – How to manage Kerberos KDC usage of RC4 for service account ticket issuance changes related to CVE-2026-20833 (KB 5073381) Microsoft Learn – Detect and Remediate RC4 Usage in Kerberos AskDS – What is going on with RC4 in Kerberos? Beyond RC4 for Windows authentication | Microsoft Windows Server Blog So, you think you’re ready for enforcing AES for Kerberos? | Microsoft Community Hub Risk Associated with the Vulnerability When RC4 is used in Kerberos tickets, an authenticated attacker can request Service Tickets (TGS) for valid SPNs, capture these tickets, and perform offline brute-force attacks, particularly Kerberoasting scenarios, with the goal of recovering service account passwords. Compared to AES, RC4 allows significantly faster cracking, especially for older accounts or accounts with weak passwords. Technical Overview of the Exploitation In simplified terms, the exploitation flow occurs as follows: The attacker requests a TGS for a valid SPN. The KDC issues the ticket using RC4, when that algorithm is still accepted. The ticket is captured and analyzed offline. The service account password is recovered. The compromised account is used for lateral movement or privilege escalation. Official Timeline Defined by Microsoft Important clarification on enforcement behavior Explicit account encryption type configurations continue to be honored even during enforcement mode. The Kerberos hardening associated with CVE‑2026‑20833 focuses on changing the default behavior of the KDC, enforcing AES-only encryption for TGS ticket issuance when no explicit configuration exists. This approach follows the same enforcement model previously applied to Kerberos session keys in earlier security updates (for example, KB5021131 related to CVE‑2022‑37966), representing another step in the progressive removal of RC4 as an implicit fallback. January 2026 – Audit Phase Starting in January 2026, Microsoft initiated the Audit Phase related to changes in RC4 usage within Kerberos, as described in the official guidance associated with CVE-2026-20833. The primary objective of this phase is to allow organizations to identify existing RC4 dependencies before enforcement changes are applied in later phases. During this phase, no functional breakage is expected, as RC4 is still permitted by the KDC. However, additional auditing mechanisms were introduced, providing greater visibility into how Kerberos tickets are issued in the environment. Analysis is primarily based on the following events recorded in the Security Log of Domain Controllers: Event ID 4768 – Kerberos Authentication Service (AS request / Ticket Granting Ticket) Event ID 4769 – Kerberos Service Ticket Operations (Ticket Granting Service – TGS) Additional events related to the KDCSVC service These events allow identification of: the account that requested authentication the requested service or SPN the source host of the request the encryption algorithm used for the ticket and session key This information is critical for detecting scenarios where RC4 is still being implicitly used, enabling operations teams to plan remediation ahead of the enforcement phase. If these events are not being logged on Domain Controllers, it is necessary to verify whether Kerberos auditing is properly enabled. For Kerberos authentication events to be recorded in the Security Log, the corresponding audit policies must be configured. The minimum recommended configuration is to enable Success auditing for the following subcategories: Kerberos Authentication Service Kerberos Service Ticket Operations Verification can be performed directly on a Domain Controller using the following commands: auditpol /get /subcategory:"Kerberos Service Ticket Operations" auditpol /get /subcategory:"Kerberos Authentication Service" In enterprise environments, the recommended approach is to apply this configuration via Group Policy, ensuring consistency across all Domain Controllers. The corresponding policy can be found at: Computer Configuration - Policies - Windows Settings - Security Settings - Advanced Audit Policy Configuration - Audit Policies - Account Logon Once enabled, these audits record events 4768 and 4769 in the Domain Controllers’ Security Log, allowing analysis tools—such as inventory scripts or SIEM/Log Analytics queries—to accurately identify where RC4 is still present in the Kerberos authentication flow. April 2026 – Enforcement with Manual Rollback With the April 2026 update, the KDC begins operating in AES-only mode (0x18) when the msDS-SupportedEncryptionTypes attribute is not defined. This means RC4 is no longer accepted as an implicit fallback. During this phase, applications, accounts, or computers that still implicitly depend on RC4 may start failing. Manual rollback remains possible via explicit configuration of the attribute in Active Directory. July 2026 – Final Enforcement Starting in July 2026, audit mode and rollback options are removed. RC4 will only function if explicitly configured—a practice that is strongly discouraged. This represents the point of no return in the hardening process. Official Monitoring Approach Microsoft provides official scripts in the repository: https://github.com/microsoft/Kerberos-Crypto/tree/main/scripts The two primary scripts used in this analysis are: Get-KerbEncryptionUsage.ps1 The Get-KerbEncryptionUsage.ps1 script, provided by Microsoft in the Kerberos‑Crypto repository, is designed to identify how Kerberos tickets are issued in the environment by analyzing authentication events recorded on Domain Controllers. Data collection is primarily based on: Event ID 4768 – Kerberos Authentication Service (AS‑REQ / TGT issuance) Event ID 4769 – Kerberos Service Ticket Operations (TGS issuance) From these events, the script extracts and consolidates several relevant fields for authentication flow analysis: Time – when the authentication occurred Requestor – IP address or host that initiated the request Source – account that requested the ticket Target – requested service or SPN Type – operation type (AS or TGS) Ticket – algorithm used to encrypt the ticket SessionKey – algorithm used to protect the session key Based on these fields, it becomes possible to objectively identify which algorithms are being used in the environment, both for ticket issuance and session establishment. This visibility is essential for detecting RC4 dependencies in the Kerberos authentication flow, enabling precise identification of which clients, services, or accounts still rely on this legacy algorithm. Example usage: .\Get-KerbEncryptionUsage.ps1 -Encryption RC4 -Searchscope AllKdcs | Export-Csv -Path .\KerbUsage_RC4_All_ThisDC.csv -NoTypeInformation -Encoding UTF8 Data Consolidation and Analysis In enterprise environments, where event volumes may be high, it is recommended to consolidate script results into analytical tools such as Power BI to facilitate visualization and investigation. The presented image illustrates an example dashboard built from collected results, enabling visibility into: Total events analyzed Number of Domain Controllers involved Number of requesting clients (Requestors) Most frequently involved services or SPNs (Targets) Temporal distribution of events RC4 usage scenarios (Ticket, SessionKey, or both) This type of visualization enables rapid identification of RC4 usage patterns, remediation prioritization, and progress tracking as dependencies are eliminated. Additionally, dashboards help answer key operational questions, such as: Which services still depend on RC4 Which clients are negotiating RC4 for sessions Which Domain Controllers are issuing these tickets Whether RC4 usage is decreasing over time This combined automated collection + analytical visualization approach is the recommended strategy to prepare environments for the Microsoft changes related to CVE‑2026‑20833 and the progressive removal of RC4 in Kerberos. Visualizing Results with Power BI To facilitate analysis and monitoring of RC4 usage in Kerberos, it is recommended to consolidate script results into a Power BI analytical dashboard. 1. Install Power BI Desktop Download and install Power BI Desktop from the official Microsoft website 2. Execute data collection After running the Get-KerbEncryptionUsage.ps1 script, save the generated CSV file to the following directory: C:\Temp\Kerberos_KDC_usage_of_RC4_Logs\KerbEncryptionUsage_RC4.csv 3. Open the dashboard in Power BI Open the file RC4-KerbEncryptionUsage-Dashboards.pbix using Power BI Desktop. If you are interested, please leave a comment on this post with your email address, and I will be happy to share with you. 4. Update the data source If the CSV file is located in a different directory, it will be necessary to adjust the data source path in Power BI. As illustrated, the dashboard uses a parameter named CsvFilePath, which defines the path to the collected CSV file. To adjust it: Open Transform Data in Power BI. Locate the CsvFilePath parameter in the list of Queries. Update the value to the directory where the CSV file was saved. Click Refresh Preview or Refresh to update the data. Click Home → Close & Apply. This approach allows rapid identification of RC4 dependencies, prioritization of remediation actions, and tracking of progress throughout the elimination process. List-AccountKeys.ps1 This script is used to identify which long-term keys are present on user, computer, and service accounts, enabling verification of whether RC4 is still required or whether AES128/AES256 keys are already available. Interpreting Observed Scenarios Microsoft recommends analyzing RC4 usage by jointly considering two key fields present in Kerberos events: Ticket Encryption Type Session Encryption Type Each combination represents a distinct Kerberos behavior, indicating the source of the issue, risk level, and remediation point in the environment. In addition to events 4768 and 4769, updates released starting January 13, 2026, introduce new Kdcsvc events in the System Event Log that assist in identifying RC4 dependencies ahead of enforcement. These events include: Event ID 201 – RC4 usage detected because the client advertises only RC4 and the service does not have msDS-SupportedEncryptionTypes defined. Event ID 202 – RC4 usage detected because the service account does not have AES keys and the msDS-SupportedEncryptionTypes attribute is not defined. Event ID 203 – RC4 usage blocked (enforcement phase) because the client advertises only RC4 and the service does not have msDS-SupportedEncryptionTypes defined. Event ID 204 – RC4 usage blocked (enforcement phase) because the service account does not have AES keys and msDS-SupportedEncryptionTypes is not defined. Event ID 205 – Detection of explicit enablement of insecure algorithms (such as RC4) in the domain policy DefaultDomainSupportedEncTypes. Event ID 206 – RC4 usage detected because the service accepts only AES, but the client does not advertise AES support. Event ID 207 – RC4 usage detected because the service is configured for AES, but the service account does not have AES keys. Event ID 208 – RC4 usage blocked (enforcement phase) because the service accepts only AES and the client does not advertise AES support. Event ID 209 – RC4 usage blocked (enforcement phase) because the service accepts only AES, but the service account does not have AES keys. https://support.microsoft.com/en-gb/topic/how-to-manage-kerberos-kdc-usage-of-rc4-for-service-account-ticket-issuance-changes-related-to-cve-2026-20833-1ebcda33-720a-4da8-93c1-b0496e1910dc They indicate situations where RC4 usage will be blocked in future phases, allowing early detection of configuration issues in clients, services, or accounts. These events are logged under: Log: System Source: Kdcsvc Below are the primary scenarios observed during the analysis of Kerberos authentication behavior, highlighting how RC4 usage manifests across different ticket and session encryption combinations. Each scenario represents a distinct risk profile and indicates specific remediation actions required to ensure compliance with the upcoming enforcement phases. Scenario A – RC4 / RC4 In this scenario, both the Kerberos ticket and the session key are issued using RC4. This is the worst possible scenario from a security and compatibility perspective, as it indicates full and explicit dependence on RC4 in the authentication flow. This condition significantly increases exposure to Kerberoasting attacks, since RC4‑encrypted tickets can be subjected to offline brute-force attacks to recover service account passwords. In addition, environments remaining in this state have a high probability of authentication failure after the April 2026 updates, when RC4 will no longer be accepted as an implicit fallback by the KDC. Events Associated with This Scenario During the Audit Phase, this scenario is typically associated with: Event ID 201 – Kdcsvc Indicates that: the client advertises only RC4 the service does not have msDS-SupportedEncryptionTypes defined the Domain Controller does not have DefaultDomainSupportedEncTypes defined This means RC4 is being used implicitly. This event indicates that the authentication will fail during the enforcement phase. Event ID 202 – Kdcsvc Indicates that: the service account does not have AES keys the service does not have msDS-SupportedEncryptionTypes defined This typically occurs when: legacy accounts have never had their passwords reset only RC4 keys exist in Active Directory Possible Causes Common causes include: the originating client (Requestor) advertises only RC4 the target service (Target) is not explicitly configured to support AES the account has only legacy RC4 keys the msDS-SupportedEncryptionTypes attribute is not defined Recommended Actions To remediate this scenario: Correctly identify the object involved in the authentication flow, typically: a service account (SPN) a computer account or a Domain Controller computer object Verify whether the object has AES keys available using analysis tools or scripts such as List-AccountKeys.ps1. If AES keys are not present, reset the account password, forcing generation of modern cryptographic keys (AES128 and AES256). Explicitly define the msDS-SupportedEncryptionTypes attribute to enable AES support. Recommended value for modern environments: 0x18 (AES128 + AES256) = 24 As illustrated below, this configuration can be applied directly to the msDS-SupportedEncryptionTypes attribute in Active Directory. AES can also be enabled via Active Directory Users and Computers by explicitly selecting: This account supports Kerberos AES 128 bit encryption This account supports Kerberos AES 256 bit encryption These options ensure that new Kerberos tickets are issued using AES algorithms instead of RC4. Temporary RC4 Usage (Controlled Rollback) In transitional scenarios—during migration or troubleshooting—it may be acceptable to temporarily use: 0x1C (RC4 + AES) = 28 This configuration allows the object to accept both RC4 and AES simultaneously, functioning as a controlled rollback while legacy dependencies are identified and corrected. However, the final objective must be to fully eliminate RC4 before the final enforcement phase in July 2026, ensuring the environment operates exclusively with AES128 and AES256. Scenario B – AES / RC4 In this case, the ticket is protected with AES, but the session is still negotiated using RC4. This typically indicates a client limitation, legacy configuration, or restricted advertisement of supported algorithms. Events Associated with This Scenario During the Audit Phase, this scenario may generate: Event ID 206 Indicates that: the service accepts only AES the client does not advertise AES in the Advertised Etypes In this case, the client is the issue. Recommended Action Investigate the Requestor Validate operating system, client type, and advertised algorithms Review legacy GPOs, hardening configurations, or settings that still force RC4 For Linux clients or third‑party applications, review krb5.conf, keytabs, and Kerberos libraries Scenario C – RC4 / AES Here, the session already uses AES, but the ticket is still issued using RC4. This indicates an implicit RC4 dependency on the Target or KDC side, and the environment may fail once enforcement begins. Events Associated with This Scenario This scenario may generate: Event ID 205 Indicates that the domain has explicit insecure algorithm configuration in: DefaultDomainSupportedEncTypes This means RC4 is explicitly allowed at the domain level. Recommended Action Correct the Target object Explicitly define msDS-SupportedEncryptionTypes with 0x18 = 24 Revalidate new ticket issuance to confirm full migration to AES / AES Conclusion CVE‑2026‑20833 represents a structural change in Kerberos behavior within Active Directory environments. Proper monitoring is essential before April 2026, and the msDS-SupportedEncryptionTypes attribute becomes the primary control point for service accounts, computer accounts, and Domain Controllers. July 2026 represents the final enforcement point, after which there will be no implicit rollback to RC4.Security as the core primitive - Securing AI agents and apps
This week at Microsoft Ignite, we shared our vision for Microsoft security -- In the agentic era, security must be ambient and autonomous, like the AI it protects. It must be woven into and around everything we build—from silicon to OS, to agents, apps, data, platforms, and clouds—and throughout everything we do. In this blog, we are going to dive deeper into many of the new innovations we are introducing this week to secure AI agents and apps. As I spend time with our customers and partners, there are four consistent themes that have emerged as core security challenges to secure AI workloads. These are: preventing agent sprawl and access to resources, protecting against data oversharing and data leaks, defending against new AI threats and vulnerabilities, and adhering to evolving regulations. Addressing these challenges holistically requires a coordinated effort across IT, developers, and security leaders, not just within security teams and to enable this, we are introducing several new innovations: Microsoft Agent 365 for IT, Foundry Control Plane in Microsoft Foundry for developers, and the Security Dashboard for AI for security leaders. In addition, we are releasing several new purpose-built capabilities to protect and govern AI apps and agents across Microsoft Defender, Microsoft Entra, and Microsoft Purview. Observability at every layer of the stack To facilitate the organization-wide effort that it takes to secure and govern AI agents and apps – IT, developers, and security leaders need observability (security, management, and monitoring) at every level. IT teams need to enable the development and deployment of any agent in their environment. To ensure the responsible and secure deployment of agents into an organization, IT needs a unified agent registry, the ability to assign an identity to every agent, manage the agent’s access to data and resources, and manage the agent’s entire lifecycle. In addition, IT needs to be able to assign access to common productivity and collaboration tools, such as email and file storage, and be able to observe their entire agent estate for risks such as over-permissioned agents. Development teams need to build and test agents, apply security and compliance controls by default, and ensure AI models are evaluated for safety guardrails and security vulnerabilities. Post deployment, development teams must observe agents to ensure they are staying on task, accessing applications and data sources appropriately, and operating within their cost and performance expectations. Security & compliance teams must ensure overall security of their AI estate, including their AI infrastructure, platforms, data, apps, and agents. They need comprehensive visibility into all their security risks- including agent sprawl and resource access, data oversharing and leaks, AI threats and vulnerabilities, and complying with global regulations. They want to address these risks by extending their existing security investments that they are already invested in and familiar with, rather than using siloed or bolt-on tools. These teams can be most effective in delivering trustworthy AI to their organizations if security is natively integrated into the tools and platforms that they use every day, and if those tools and platforms share consistent security primitives such as agent identities from Entra; data security and compliance controls from Purview; and security posture, detections, and protections from Defender. With the new capabilities being released today, we are delivering observability at every layer of the AI stack, meeting IT, developers, and security teams where they are in the tools they already use to innovate with confidence. For IT Teams - Introducing Microsoft Agent 365, the control plane for agents, now in preview The best infrastructure for managing your agents is the one you already use to manage your users. With Agent 365, organizations can extend familiar tools and policies to confidently deploy and secure agents, without reinventing the wheel. By using the same trusted Microsoft 365 infrastructure, productivity apps, and protections, organizations can now apply consistent and familiar governance and security controls that are purpose-built to protect against agent-specific threats and risks. gement and governance of agents across organizations Microsoft Agent 365 delivers a unified agent Registry, Access Control, Visualization, Interoperability, and Security capabilities for your organization. These capabilities work together to help organizations manage agents and drive business value. The Registry powered by the Entra provides a complete and unified inventory of all the agents deployed and used in your organization including both Microsoft and third-party agents. Access Control allows you to limit the access privileges of your agents to only the resources that they need and protect their access to resources in real time. Visualization gives organizations the ability to see what matters most and gain insights through a unified dashboard, advanced analytics, and role-based reporting. Interop allows agents to access organizational data through Work IQ for added context, and to integrate with Microsoft 365 apps such as Outlook, Word, and Excel so they can create and collaborate alongside users. Security enables the proactive detection of vulnerabilities and misconfigurations, protects against common attacks such as prompt injections, prevents agents from processing or leaking sensitive data, and gives organizations the ability to audit agent interactions, assess compliance readiness and policy violations, and recommend controls for evolving regulatory requirements. Microsoft Agent 365 also includes the Agent 365 SDK, part of Microsoft Agent Framework, which empowers developers and ISVs to build agents on their own AI stack. The SDK enables agents to automatically inherit Microsoft's security and governance protections, such as identity controls, data security policies, and compliance capabilities, without the need for custom integration. For more details on Agent 365, read the blog here. For Developers - Introducing Microsoft Foundry Control Plane to observe, secure and manage agents, now in preview Developers are moving fast to bring agents into production, but operating them at scale introduces new challenges and responsibilities. Agents can access tools, take actions, and make decisions in real time, which means development teams must ensure that every agent behaves safely, securely, and consistently. Today, developers need to work across multiple disparate tools to get a holistic picture of the cybersecurity and safety risks that their agents may have. Once they understand the risk, they then need a unified and simplified way to monitor and manage their entire agent fleet and apply controls and guardrails as needed. Microsoft Foundry provides a unified platform for developers to build, evaluate and deploy AI apps and agents in a responsible way. Today we are excited to announce that Foundry Control Plane is available in preview. This enables developers to observe, secure, and manage their agent fleets with built-in security, and centralized governance controls. With this unified approach, developers can now identify risks and correlate disparate signals across their models, agents, and tools; enforce consistent policies and quality gates; and continuously monitor task adherence and runtime risks. Foundry Control Plane is deeply integrated with Microsoft’s security portfolio to provide a ‘secure by design’ foundation for developers. With Microsoft Entra, developers can ensure an agent identity (Agent ID) and access controls are built into every agent, mitigating the risk of unmanaged agents and over permissioned resources. With Microsoft Defender built in, developers gain contextualized alerts and posture recommendations for agents directly within the Foundry Control Plane. This integration proactively prevents configuration and access risks, while also defending agents from runtime threats in real time. Microsoft Purview’s native integration into Foundry Control Plane makes it easy to enable data security and compliance for every Foundry-built application or agent. This allows Purview to discover data security and compliance risks and apply policies to prevent user prompts and AI responses from safety and policy violations. In addition, agent interactions can be logged and searched for compliance and legal audits. This integration of the shared security capabilities, including identity and access, data security and compliance, and threat protection and posture ensures that security is not an afterthought; it’s embedded at every stage of the agent lifecycle, enabling you to start secure and stay secure. For more details, read the blog. For Security Teams - Introducing Security Dashboard for AI - unified risk visibility for CISOs and AI risk leaders, coming soon AI proliferation in the enterprise, combined with the emergence of AI governance committees and evolving AI regulations, leaves CISOs and AI risk leaders needing a clear view of their AI risks, such as data leaks, model vulnerabilities, misconfigurations, and unethical agent actions across their entire AI estate, spanning AI platforms, apps, and agents. 90% of security professionals, including CISOs, report that their responsibilities have expanded to include data governance and AI oversight within the past year. 1 At the same time, 86% of risk managers say disconnected data and systems lead to duplicated efforts and gaps in risk coverage. 2 To address these needs, we are excited to introduce the Security Dashboard for AI. This serves as a unified dashboard that aggregates posture and real-time risk signals from Microsoft Defender, Microsoft Entra, and Microsoft Purview. This unified dashboard allows CISOs and AI risk leaders to discover agents and AI apps, track AI posture and drift, and correlate risk signals to investigate and act across their entire AI ecosystem. For example, you can see your full AI inventory and get visibility into a quarantined agent, flagged for high data risk due to oversharing sensitive information in Purview. The dashboard then correlates that signal with identity insights from Entra and threat protection alerts from Defender to provide a complete picture of exposure. From there, you can delegate tasks to the appropriate teams to enforce policies and remediate issues quickly. With the Security Dashboard for AI, CISOs and risk leaders gain a clear, consolidated view of AI risks across agents, apps, and platforms—eliminating fragmented visibility, disconnected posture insights, and governance gaps as AI adoption scales. Best of all, there’s nothing new to buy. If you’re already using Microsoft security products to secure AI, you’re already a Security Dashboard for AI customer. Figure 5: Security Dashboard for AI provides CISOs and AI risk leaders with a unified view of their AI risk by bringing together their AI inventory, AI risk, and security recommendations to strengthen overall posture Together, these innovations deliver observability and security across IT, development, and security teams, powered by Microsoft’s shared security capabilities. With Microsoft Agent 365, IT teams can manage and secure agents alongside users. Foundry Control Plane gives developers unified governance and lifecycle controls for agent fleets. Security Dashboard for AI provides CISOs and AI risk leaders with a consolidated view of AI risks across platforms, apps, and agents. Added innovation to secure and govern your AI workloads In addition to the IT, developer, and security leader-focused innovations outlined above, we continue to accelerate our pace of innovation in Microsoft Entra, Microsoft Purview, and Microsoft Defender to address the most pressing needs for securing and governing your AI workloads. These needs are: Manage agent sprawl and resource access e.g. managing agent identity, access to resources, and permissions lifecycle at scale Prevent data oversharing and leaks e.g. protecting sensitive information shared in prompts, responses, and agent interactions Defend against shadow AI, new threats, and vulnerabilities e.g. managing unsanctioned applications, preventing prompt injection attacks, and detecting AI supply chain vulnerabilities Enable AI governance for regulatory compliance e.g. ensuring AI development, operations, and usage comply with evolving global regulations and frameworks Manage agent sprawl and resource access 76% of business leaders expect employees to manage agents within the next 2–3 years. 3 Widespread adoption of agents is driving the need for visibility and control, which includes the need for a unified registry, agent identities, lifecycle governance, and secure access to resources. Today, Microsoft Entra provides robust identity protection and secure access for applications and users. However, organizations lack a unified way to manage, govern, and protect agents in the same way they manage their users. Organizations need a purpose-built identity and access framework for agents. Introducing Microsoft Entra Agent ID, now in preview Microsoft Entra Agent ID offers enterprise-grade capabilities that enable organizations to prevent agent sprawl and protect agent identities and their access to resources. These new purpose-built capabilities enable organizations to: Register and manage agents: Get a complete inventory of the agent fleet and ensure all new agents are created with an identity built-in and are automatically protected by organization policies to accelerate adoption. Govern agent identities and lifecycle: Keep the agent fleet under control with lifecycle management and IT-defined guardrails for both agents and people who create and manage them. Protect agent access to resources: Reduce risk of breaches, block risky agents, and prevent agent access to malicious resources with conditional access and traffic inspection. Agents built in Microsoft Copilot Studio, Microsoft Foundry, and Security Copilot get an Entra Agent ID built-in at creation. Developers can also adopt Entra Agent ID for agents they build through Microsoft Agent Framework, Microsoft Agent 365 SDK, or Microsoft Entra Agent ID SDK. Read the Microsoft Entra blog to learn more. Prevent data oversharing and leaks Data security is more complex than ever. Information Security Media Group (ISMG) reports that 80% of leaders cite leakage of sensitive data as their top concern. 4 In addition to data security and compliance risks of generative AI (GenAI) apps, agents introduces new data risks such as unsupervised data access, highlighting the need to protect all types of corporate data, whether it is accessed by employees or agents. To mitigate these risks, we are introducing new Microsoft Purview data security and compliance capabilities for Microsoft 365 Copilot and for agents and AI apps built with Copilot Studio and Microsoft Foundry, providing unified protection, visibility, and control for users, AI Apps, and Agents. New Microsoft Purview controls safeguard Microsoft 365 Copilot with real-time protection and bulk remediation of oversharing risks Microsoft Purview and Microsoft 365 Copilot deliver a fully integrated solution for protecting sensitive data in AI workflows. Based on ongoing customer feedback, we’re introducing new capabilities to deliver real-time protection for sensitive data in M365 Copilot and accelerated remediation of oversharing risks: Data risk assessments: Previously, admins could monitor oversharing risks such as SharePoint sites with unprotected sensitive data. Now, they can perform item-level investigations and bulk remediation for overshared files in SharePoint and OneDrive to quickly reduce oversharing exposure. Data Loss Prevention (DLP) for M365 Copilot: DLP previously excluded files with sensitivity labels from Copilot processing. Now in preview, DLP also prevents prompts that include sensitive data from being processed in M365 Copilot, Copilot Chat, and Copilot agents, and prevents Copilot from using sensitive data in prompts for web grounding. Priority cleanup for M365 Copilot assets: Many organizations have org-wide policies to retain or delete data. Priority cleanup, now generally available, lets admins delete assets that are frequently processed by Copilot, such as meeting transcripts and recordings, on an independent schedule from the org-wide policies while maintaining regulatory compliance. On-demand classification for meeting transcripts: Purview can now detect sensitive information in meeting transcripts on-demand. This enables data security admins to apply DLP policies and enforce Priority cleanup based on the sensitive information detected. & bulk remediation Read the full Data Security blog to learn more. Introducing new Microsoft Purview data security capabilities for agents and apps built with Copilot Studio and Microsoft Foundry, now in preview Microsoft Purview now extends the same data security and compliance for users and Copilots to agents and apps. These new capabilities are: Enhanced Data Security Posture Management: A centralized DSPM dashboard that provides observability, risk assessment, and guided remediation across users, AI apps, and agents. Insider Risk Management (IRM) for Agents: Uniquely designed for agents, using dedicated behavioral analytics, Purview dynamically assigns risk levels to agents based on their risky handing of sensitive data and enables admins to apply conditional policies based on that risk level. Sensitive data protection with Azure AI Search: Azure AI Search enables fast, AI-driven retrieval across large document collections, essential for building AI Apps. When apps or agents use Azure AI Search to index or retrieve data, Purview sensitivity labels are preserved in the search index, ensuring that any sensitive information remains protected under the organization’s data security & compliance policies. For more information on preventing data oversharing and data leaks - Learn how Purview protects and governs agents in the Data Security and Compliance for Agents blog. Defend against shadow AI, new threats, and vulnerabilities AI workloads are subject to new AI-specific threats like prompt injections attacks, model poisoning, and data exfiltration of AI generated content. Although security admins and SOC analysts have similar tasks when securing agents, the attack methods and surfaces differ significantly. To help customers defend against these novel attacks, we are introducing new capabilities in Microsoft Defender that deliver end-to-end protection, from security posture management to runtime defense. Introducing Security Posture Management for agents, now in preview As organizations adopt AI agents to automate critical workflows, they become high-value targets and potential points of compromise, creating a critical need to ensure agents are hardened, compliant, and resilient by preventing misconfigurations and safeguarding against adversarial manipulation. Security Posture Management for agents in Microsoft Defender now provides an agent inventory for security teams across Microsoft Foundry and Copilot Studio agents. Here, analysts can assess the overall security posture of an agent, easily implement security recommendations, and identify vulnerabilities such as misconfigurations and excessive permissions, all aligned to the MITRE ATT&CK framework. Additionally, the new agent attack path analysis visualizes how an agent’s weak security posture can create broader organizational risk, so you can quickly limit exposure and prevent lateral movement. Introducing Threat Protection for agents, now in preview Attack techniques and attack surfaces for agents are fundamentally different from other assets in your environment. That’s why Defender is delivering purpose-built protections and detections to help defend against them. Defender is introducing runtime protection for Copilot Studio agents that automatically block prompt injection attacks in real time. In addition, we are announcing agent-specific threat detections for Copilot Studio and Microsoft Foundry agents coming soon. Defender automatically correlates these alerts with Microsoft’s industry-leading threat intelligence and cross-domain security signals to deliver richer, contextualized alerts and security incident views for the SOC analyst. Defender’s risk and threat signals are natively integrated into the new Microsoft Foundry Control Plane, giving development teams full observability and the ability to act directly from within their familiar environment. Finally, security analysts will be able to hunt across all agent telemetry in the Advanced Hunting experience in Defender, and the new Agent 365 SDK extends Defender’s visibility and hunting capabilities to third-party agents, starting with Genspark and Kasisto, giving security teams even more coverage across their AI landscape. To learn more about how you can harden the security posture of your agents and defend against threats, read the Microsoft Defender blog. Enable AI governance for regulatory compliance Global AI regulations like the EU AI Act and NIST AI RMF are evolving rapidly; yet, according to ISMG, 55% of leaders report lacking clarity on current and future AI regulatory requirements. 5 As enterprises adopt AI, they must ensure that their AI innovation aligns with global regulations and standards to avoid costly compliance gaps. Introducing new Microsoft Purview Compliance Manager capabilities to stay ahead of evolving AI regulations, now in preview Today, Purview Compliance Manager provides over 300 pre-built assessments for common industry, regional, and global standards and regulations. However, the pace of change for new AI regulations requires controls to be continuously re-evaluated and updated so that organizations can adapt to ongoing changes in regulations and stay compliant. To address this need, Compliance Manager now includes AI-powered regulatory templates. AI-powered regulatory templates enable real-time ingestion and analysis of global regulatory documents, allowing compliance teams to quickly adapt to changes as they happen. As regulations evolve, the updated regulatory documents can be uploaded to Compliance Manager, and the new requirements are automatically mapped to applicable recommended actions to implement controls across Microsoft Defender, Microsoft Entra, Microsoft Purview, Microsoft 365, and Microsoft Foundry. Automated actions by Compliance Manager further streamline governance, reduce manual workload, and strengthen regulatory accountability. Introducing expanded Microsoft Purview compliance capabilities for agents and AI apps now in preview Microsoft Purview now extends its compliance capabilities across agent-generated interactions, ensuring responsible use and regulatory alignment as AI becomes deeply embedded across business processes. New capabilities include expanded coverage for: Audit: Surface agent interactions, lifecycle events, and data usage with Purview Audit. Unified audit logs across user and agent activities, paired with traceability for every agent using an Entra Agent ID, support investigation, anomaly detection, and regulatory reporting. Communication Compliance: Detect prompts sent to agents and agent-generated responses containing inappropriate, unethical, or risky language, including attempts to manipulate agents into bypassing policies, generating risky content, or producing noncompliant outputs. When issues arise, data security admins get full context, including the prompt, the agent’s output, and relevant metadata, so they can investigate and take corrective action Data Lifecycle Management: Apply retention and deletion policies to agent-generated content and communication flows to automate lifecycle controls and reduce regulatory risk. Read about Microsoft Purview data security for agents to learn more. Finally, we are extending our data security, threat protection, and identity access capabilities to third-party apps and agents via the network. Advancing Microsoft Entra Internet Access Secure Web + AI Gateway - extend runtime protections to the network, now in preview Microsoft Entra Internet Access, part of the Microsoft Entra Suite, has new capabilities to secure access to and usage of GenAI at the network level, marking a transition from Secure Web Gateway to Secure Web and AI Gateway. Enterprises can accelerate GenAI adoption while maintaining compliance and reducing risk, empowering employees to experiment with new AI tools safely. The new capabilities include: Prompt injection protection which blocks malicious prompts in real time by extending Azure AI Prompt Shields to the network layer. Network file filtering which extends Microsoft Purview to inspect files in transit and prevents regulated or confidential data from being uploaded to unsanctioned AI services. Shadow AI Detection that provides visibility into unsanctioned AI applications through Cloud Application Analytics and Defender for Cloud Apps risk scoring, empowering security teams to monitor usage trends, apply Conditional Access, or block high-risk apps instantly. Unsanctioned MCP server blocking prevents access to MCP servers from unauthorized agents. With these controls, you can accelerate GenAI adoption while maintaining compliance and reducing risk, so employees can experiment with new AI tools safely. Read the Microsoft Entra blog to learn more. As AI transforms the enterprise, security must evolve to meet new challenges—spanning agent sprawl, data protection, emerging threats, and regulatory compliance. Our approach is to empower IT, developers, and security leaders with purpose-built innovations like Agent 365, Foundry Control Plane, and the Security Dashboard for AI. These solutions bring observability, governance, and protection to every layer of the AI stack, leveraging familiar tools and integrated controls across Microsoft Defender, Microsoft Entra, and Microsoft Purview.

Publisher screening is a software supply-chain reality: if a publisher account is compromised, a single update can reach thousands of machines—and recovery is costly. Microsoft Trust & Security Services applies AI to automate screening at onboarding and keep reassessing publishers as new signals appear. Multiple “checker” agents evaluate identity, reputation, and post-approval behavior, then combine evidence into a consistent risk score and an approve/deny/escalate decision, with an evidence-backed explanation that supports auditability and appeals while reducing operational toil.Security Community Spotlight: Luca Romero Arrieche Heller
Meet Luca, Modern Workplace and Cloud Consultant at SoftwareOne Iberia, a Microsoft Partner. Luca has been working with Microsoft Security and cloud technologies for over a decade, closely following the evolution of the Microsoft Security ecosystem. Today, Luca focuses on Modern Work and security transformation projects, including large-scale Microsoft 365 migrations, enterprise messaging modernization with Exchange Online, endpoint management deployments with Microsoft Intune, and identity-driven security architectures across Microsoft environments. In addition to implementation projects, Luca also delivers technical workshops focused on threat protection and Microsoft security technologies, helping organizations better understand and implement solutions such as Microsoft Defender XDR, Microsoft Entra ID, endpoint security, and Zero Trust strategies to strengthen their overall security posture. Here’s what Luca had to say about his winding road through Microsoft Security and its Community. All responses are quotes from Luca. Microsoft Security Community How would you describe your Microsoft Security Community involvement or advocacy, globally and/or locally? When did you begin? My involvement with the Microsoft Community began early in my career through regional Microsoft community and influencer programs in Brazil. During that time, I became involved with Microsoft Virtual Academy (MVA) and started writing security-focused technical articles based on real project experience. My early technical journey began working with on-premises technologies such as ISA Server, Exchange Server, and Active Directory, which provided a strong foundation in Microsoft infrastructure and security. Through community participation and my blog, I began documenting real-world implementations and lessons learned related to Microsoft Security and cloud technologies. Over the years, my professional work has remained closely connected to the Microsoft ecosystem, implementing technologies such as Advanced Threat Analytics (ATA), Advanced Threat Protection (ATP), Microsoft Defender XDR, Microsoft Entra ID, and Microsoft Intune in enterprise environments. Today, my community advocacy is strongly connected to real-world experience, focusing on Zero Trust architectures, identity protection, modern endpoint security, and large-scale Microsoft 365 transformations and migrations. I noticed you’ve also answered a number of questions and have helped provide solutions in Microsoft Tech Community forums. How did you come across this and what inspired you to help? I have always been encouraged to participate in the technical community and share knowledge. Since the early days of TechNet, I have been involved in learning from others and contributing whenever possible. The culture of collaboration within the Microsoft ecosystem played an important role in my professional development. Many of the challenges I faced early in my career were solved thanks to the knowledge shared by the community. Because of that, contributing back feels natural. In the Microsoft Security Tech Community forums, I often see questions that are very similar to challenges I face in my daily work as a consultant. Sharing my experience becomes a practical way to help others navigate similar situations. Experience is important not only for solving problems, but also for knowing where to look and how to approach a solution. When I see questions without answers or clear guidance, I try to contribute by sharing practical insights, troubleshooting approaches, and real-world solutions. What do you find most rewarding about being a member of the Microsoft Security Community? What I find most rewarding is knowing that the community played a direct role in shaping my professional journey. Early in my career, I learned extensively through forums, technical discussions, and shared knowledge. That collaborative environment enabled me to grow into increasingly complex enterprise projects. Over the years, I have followed the evolution of Microsoft Security solutions... the community has always been part of that journey. Today, being able to contribute insights gained from large-scale security architectures, identity modernization, and enterprise Microsoft 365 migrations is my way of giving back. Additionally, as a founding member of Microsoft Virtual Academy, I published security-focused technical articles and created my blog to document real-world implementations, always referencing sources and applied knowledge. Speaking of Microsoft Security solutions...which feature or product has provided the most impact? How has it helped you or your customers? The combination of Entra ID Protection with Conditional Access and the unified visibility of Defender XDR (are the Microsoft Security products that have) delivered the greatest impact by reducing compromised credential risks and accelerating incident response through identity, endpoint, and cloud workload correlation. Back to the Microsoft Community- what advice do you have for others who would like to get involved? My advice is simple: start by learning, then share what you have genuinely implemented in practice. The community values real-world experience, technical honesty, and genuine collaboration. It’s not about visibility — it’s about adding value. Be consistent, support others, and document your journey. Impact follows naturally. Linking up with Luca Do you have anything you’d like to promote or recommend? I recommend diving deeper into Intune, Defender, and Exchange Online, especially focusing on the integration between identity, endpoint protection, and email security within a well-structured Zero Trust Where can people get in touch with you or follow your content? LinkedIn: https://www.linkedin.com/in/lucarheller GitHub: https://github.com/LucaARHeller Blog: https://lucaheller.wordpress.com/ Microsoft Tech Community: LucaHeller Please share anything else essential to you. Before thinking about advanced security tools, it is essential to understand how the underlying technologies work. Whether it is something simple like DNS resolution, how authentication flows operate, or how policies are applied across enterprise environments, these foundational concepts are what allow security architectures to be built correctly. For me, combining strong technical fundamentals with modern security technologies and real-world implementation experience is what enables organizations to build secure and resilient Microsoft environments. Luca’s story is a strong reminder of what makes the Microsoft Security Community thrive: practical contributions grounded in real-world experience. Through training, documenting, and showing up to help others, Luca demonstrates how continuous learning and compassion can benefit everyone. The community is better for his continued involvement, and his journey is an invitation for others to participate, share what they’ve learned, and keep strengthening security together. __________________________________________________________________________________________________________________________________________________________________ Learn and Engage with the Microsoft Security Community Log in and follow this Microsoft Security Community Blog.

Security teams are facing more threats, more complexity, and more pressure to act quickly - without increasing risk or operational overhead. What matters is being able to find the right capability, deploy it safely, and use it where security work already happens. Microsoft Security Store was built with that goal in mind. It provides a single, trusted place to discover, purchase, and deploy Microsoft and partner-built security agents and solutions that extend Microsoft Security - helping you improve protection across SOC, identity, and data protection workflows. Today, the Security Store includes 75+ security agents and 115+ solutions from Microsoft and trusted partners - each designed to integrate directly into Microsoft Security experiences and meet enterprise security requirements. At RSAC 2026, we’re announcing capabilities that make it easier to turn security intent into action- by improving how you discover agents, how quickly you can put them to use, and how effectively you can apply them across workflows to achieve your security outcomes. Meet the Next Generation of Security Agents Security agents are becoming part of day-to-day operations for many teams - helping automate investigations, enrich signals, and reduce manual effort across common security tasks. Since Security Store became generally available, Microsoft and our partners have continued to expand the set of agents that integrate directly with Microsoft Defender, Sentinel, Entra, Purview, Intune and Security Copilot. Some of the notable partner-built agents available through Security Store include: XBOW Continuous Penetration Testing Agent XBOW’s penetration testing agents perform pen-tests, analyzes findings, and correlates those findings with a customer’s Microsoft Defender detections. XBOW integrates offensive security directly into Microsoft Security workflows by streaming validated, exploitable AppSec findings into Microsoft Sentinel and enabling investigation through XBOW's Copilot agents in Microsoft Defender. With XBOW’s pen-testing agents, offensive security can run continuously to identify which vulnerabilities are actually exploitable, and how to improve posture and detections. Tanium Incident Scoping Agent The Tanium Incident Scoping Agent (In Preview) is bringing real-time endpoint intelligence directly into Microsoft Defender and Microsoft Security Copilot workflows. The agent automatically scopes incidents, identifies impacted devices, and surfaces actionable context in minutes-helping teams move faster from detection to containment. By combining Tanium’s real-time intelligence with Microsoft Security investigations, you can reduce manual effort, accelerate response, and maintain enterprise-grade governance and control. Zscaler In Microsoft Sentinel, the Zscaler ZIA–ZPA Correlation Agent correlates ZIA and ZPA activity for a given user to speed malsite/malware investigations. It highlights suspicious patterns and recommends ZIA/ZPA policy changes to reduce repeat exposure. These agents build on a growing ecosystem of Microsoft and partner capabilities designed to work together, allowing you to extend Microsoft Security with specialized expertise where it has the most impact. Discover and Deploy Agents and Solutions in the Flow of Security Work Security teams work best when they don’t have to switch tools to make decisions. That’s why Security Store is embedded directly into Microsoft Security experiences - so you can discover and evaluate trusted agents and solutions in context, while working in the tools you already use. When Security Store became generally available, we embedded it into Microsoft Defender, allowing SOC teams to discover and deploy trusted Microsoft and partner‑built agents and solutions in the middle of active investigations. Analysts can now automate response, enrich investigations, and resolve threats all within the Defender portal. At RSAC, we’re expanding this approach across identity and data security. Strengthening Identity Security with Security Store in Microsoft Entra Identity has become a primary attack surface - from fraud and automated abuse to privileged access misuse and posture gaps. Security Store is now embedded in Microsoft Entra, allowing identity and security teams to discover and deploy partner solutions and agents directly within identity workflows. For external and verified identity scenarios, Security Store includes partner solutions that integrate with Entra External ID and Entra Verified ID to help protect against fraud, DDoS attacks, and intelligent bot abuse. These solutions, built by partners such as IDEMIA, AU10TIX, TrueCredential, HUMAN Security, Akamai and Arkose Labs help strengthen trust while preserving seamless user experiences. For enterprise identity security, more than 15 agents available through the Entra Security Store provide visibility into privileged activity and identity risk, posture health and trends, and actionable recommendations to improve identity security and overall security score. These agents are built by partners such as glueckkanja, adaQuest, Ontinue, BlueVoyant, Invoke, and Performanta. This allows you to extend Entra with specialized identity security capabilities, without leaving the identity control plane. Extending Data Protection with Security Store in Microsoft Purview Protecting sensitive data requires consistent controls across where data lives and how it moves. Security Store is now embedded in Microsoft Purview, enabling teams responsible for data protection and compliance to discover partner solutions directly within Purview DLP workflows. Through this experience, you can extend Microsoft Purview DLP with partner data security solutions that help protect sensitive data across cloud applications, enterprise browsers, and networks. These include solutions from Microsoft Entra Global Secure Access and partners such as Netskope, Island, iBoss, and Palo Alto Networks. This experience will be available to customers later this month, as reflected on the M365 roadmap. By discovering solutions in context, teams can strengthen data protection without disrupting established compliance workflows. Across Defender, Entra, and Purview, purchases continue to be completed through the Security Store website, ensuring a consistent, secure, and governed transaction experience - while discovery and evaluation happen exactly where teams already work. Outcome-Driven Discovery, with Security Store Advisor As the number of agents and solutions in the Store grow, finding the right fit for your security scenario quickly becomes more important. That’s why we’re introducing the AI‑guided Security Store Advisor, now generally available. You can describe your goal in natural language - such as “investigate suspicious network activity” and receive recommendations aligned to that outcome. Advisor also includes side-by-side comparison views for agents and solutions, helping you review capabilities, integrated services, and deployment requirements more quickly and reduce evaluation time. Security Store Advisor is designed with Responsible AI principles in mind, including transparency and explainability. You can learn more about how Responsible AI is applied in this experience in the Security Store Advisor Responsible AI FAQ. Overall, this outcome‑driven approach reduces time to value, improves solution fit, and helps your team move faster from intent to action. Learning from the Security Community with Ratings and Reviews Security decisions are strongest when informed by real world use cases. This is why we are introducing Security Store ratings and reviews from security professionals who have deployed and used agents and solutions in production environments. These reviews focus on practical considerations such as integration quality, operational impact, and ease of use, helping you learn from peers facing similar security challenges. By sharing feedback, the security community helps raise the bar for quality and enables faster, more informed decisions, so teams can adopt agents and solutions with greater confidence and reduce time to value. Making agents easier to use post deployment Once you’ve deployed your agents, we’re introducing several new capabilities that make it easier to work with your agents in your daily workflows. These updates help you operationalize agents faster and apply automation where it delivers real value. Interactive chat with agents in Microsoft Defender lets SOC analysts ask questions to agents with specialized expertise, such as understanding impacted devices or understanding what vulnerabilities to prioritize directly in the Defender portal. By bringing a conversational experience with agents into the place where analysts do most of their investigation work, analysts can seamlessly work in collaboration with agents to improve security. Logic App triggers for agents enables security teams to include security agents in their automated, repeatable workflows. With this update, organizations can apply agentic automation to a wider variety of security tasks while integrating with their existing tools and workflows to perform tasks like incident triage and access reviews. Product combinations in Security Store make it easier to deploy complete security solutions from a single streamlined flow - whether that includes connectors, SaaS tools, or multiple agents that need to work together. Increasingly, partners are building agents that are adept at using your SaaS security tools and security data to provide intelligent recommendations - this feature helps you deploy them faster with ease. A Growing Ecosystem Focused on Security Outcomes As the Security Store ecosystem continues to expand, you gain access to a broader set of specialized agents and solutions that work together to help defend your environment - extending Microsoft Security with partner innovation in a governed and integrated way. At the same time, Security Store provides partners a clear path to deliver differentiated capabilities directly into Microsoft Security workflows, aligned to how customers evaluate, adopt, and use security solutions.

Quarantine "finger print matching" false positive
Just done my regular quarantine check on our O365 tenant and was surprised to find a couple of legit messages from an external sender which were flagged as High Confidence Phish based on finger print matching, which I understand translates to a close match to a previously detected malicious message. I can see absolutely nothing wrong with the message and it was so very business specific in its content that I cannot see that it would closely match anything else that had ever gone before. The recipient tells me they regularly exchange business emails with the sender without any issue. When I run off a report and look at other recent messages caught by finger print matching on my tenant, they were the usual phishing emails that are probably doing the rounds globally and were correctly trapped. Questions are: 1. Anyone know why something so highly specific in its content would be trapped in this way? 2. I feel I can't trust O365 to correctly quarantine based on this example, but High Confidence Phish is currently set to have the AdminOnlyAccessPolicy applied on my tenant - and this doesn't notify. Is there any way for a sys admin (only) to be notified by email when something goes into quarantine? I can set up a custom policy to allow RECIPIENT notification but I don't really want to involve them when messages are being correctly quarantined almost all of the time. Ours is a non-profit tenant so I can't be sitting around watching it all day - I need it to tell me when something has happened! Thanks for any ideas!Security Dashboard for AI - Now Generally Available
