Stop identity attacks before they start with Microsoft ISPM recommendations
Many major breaches involve compromised identities, excessive privileges, or misconfigured access. Long before ransomware detonates or data leaves the building, adversaries are quietly abusing valid accounts, excessive privileges or other misconfigurations to move deeper into the environment. Identity has become one of the most important attack surfaces you defend. That is why Microsoft has a dedicated team of researchers who study how identity attacks actually happen. Just as important, we turn what they learn into action. Real attacker behavior becomes concrete recommendations you can use to harden your environment before an attack begins. With Microsoft Defender, that research reaches you as Identity Security Posture Management (ISPM) recommendations: prioritized guidance that tells you what to fix, why it matters, and how to remediate it. What are identity security posture recommendations? Identity security posture recommendations are prioritized, attack-driven recommendations that address the weaknesses attackers exploit most, from overprivileged accounts to weak credentials and risky permissions. Rather than handing you a long hygiene checklist, ISPM recommendations tie each recommendation to a real attack technique. That shifts the question from "what setting do I need to change?" to "what attack am I going to prevent today?" That framing also changes how you prioritize. You can start with the fixes that close the most dangerous attack paths first, not just the ones that are quickest to clear. It gives identity admins and the SOC and others shared view of the same risk, and as our researchers uncover new techniques, the recommendations evolve, so your posture keeps pace with the threat. New recommendations We are excited to announce five new ISPM recommendations geared toward emerging attack patterns you need to be aware of: Ensure no privileged SaaS app accounts exist outside of IdP control Most SaaS platforms let you create admin accounts directly inside the app, separate from your corporate identity provider (IdP). Those local admins are convenient, but they sit outside the protections every other identity relies on: No outside centrally managed identity controls as Conditional Access, and little to no monitoring. Attackers know it. We’ve seen a rise in SaaS data-exfiltration campaigns that specifically hunt for these app-native admin accounts, because once they find one they can sign in and operate without tripping any of your usual defenses. This recommendation surfaces those accounts so you can bring them under your identity provider, where you can manage them with single sign-on, multifactor authentication, Conditional Access, and lifecycle governance apply automatically and where your SOC can finally see them. This attack pattern aligns with MITRE ATT&CK techniques including Valid Cloud Accounts (T1078.004) and Account Manipulation (T1098). Ensure service accounts are not assigned Domain Admin or Global Admin roles Service accounts run your apps and integrations, and because they are not tied to a person, they are easy to over-provision and easy to forget. When one is assigned Domain Admin or Global Admin, it becomes a quiet path to the top of your environment. Supply-chain intrusions like SolarWinds showed how attackers ride a trusted service identity straight into the highest levels of access, often without anyone noticing, because no one watches a service account the way they watch a user. This recommendation flags service accounts holding those top-tier roles so you can right-size them. It shrinks the blast radius if one is ever compromised and keeps a non-human account from becoming a hidden administrative backdoor. This attack pattern aligns with MITRE ATT&CK techniques including Valid Accounts: Domain Accounts (T1078.002) and Cloud Accounts (T1078.004) Ensure non-admin accounts cannot reset passwords for sensitive groups Sometimes a standard user account quietly holds the ability to reset passwords for members of a sensitive group, a leftover of delegated permissions no one revisited. On paper that user is low privilege. In practice they are one password reset away from becoming an administrator. Attackers look for exactly this kind of shadow admin: compromise an unremarkable account, reset a privileged password, and walk in through the front door, no exploit required. This recommendation finds those unintended password-reset rights over sensitive groups and helps you remove them, closing a direct path from ordinary user to full administrator. This attack pattern aligns with MITRE ATT&CK techniques as Account Manipulation (T1098) Ensure non-admin identities cannot have WriteDACL permissions on sensitive groups Deep in Active Directory, some permissions can be abused to grant additional rights and gain control of a sensitive group. One of them, the right to modify an object's access control list (known as WriteDACL), is especially dangerous in the wrong hands. If a non-admin identity holds it over a sensitive group, that identity can simply rewrite the group's permissions and grant itself privileged control. It is one of the most reliable escalation paths attackers use. This recommendation identifies non-admin identities with that permission over sensitive groups so you can strip it, eliminating a well-worn route from a regular account to Domain Admin. This attack pattern aligns with MITRE ATT&CK techniques as Account Manipulation (T1098) Ensure external and guest accounts are not granted privileged roles Guest and external accounts make collaboration easy, but they live partly outside your control. Their security depends on another organization's hygiene, and they blend in, which makes them an attractive target. When one of these accounts is also granted a privileged role, a single compromise on the other side of that relationship becomes a privileged foothold inside your tenant. This recommendation highlights external and guest identities holding sensitive roles so you can remove that access, preventing an outside account from being used for persistence, escalation, or reaching your data. This attack pattern aligns with MITRE ATT&CK techniques as Valid Cloud Accounts (T1078.004) and Account Manipulation Cloud Roles (T1098.003) Additional high-impact identity posture recommendations In addition to the five new recommendations, several existing ISPM recommendations remain especially important. We continue to see attackers exploit the weaknesses they address, which makes them high-value fixes for strengthening your identity posture. Here is why each one still earns priority. Remove dormant accounts from sensitive groups A privileged account no one uses is a gift to an attacker. It still carries powerful access, but because nobody signs into it, nobody notices when someone else does. Ransomware crews and intrusion groups seek out these forgotten admin accounts precisely because they can operate from one for weeks without raising suspicion. Removing dormant privileged accounts takes that stealthy, high-impact option off the table before it is ever used. Reduce lateral movement path risk to sensitive entities Reduce lateral movement path risk to sensitive entities helps close one of the most common ways identity attacks become domain-wide compromises: an attacker starts with a non-sensitive account, then follows permissions, group memberships, local admin rights, active sessions, or other identity relationships until they can reach highly sensitive credentials. This maps to well-known lateral movement and privilege escalation techniques, where adversaries abuse excessive permissions or exposed credential paths to move from an initial foothold toward Domain Admin or another high-value identity. This recommendation highlights exposed entities with risky lateral movement paths and provides remediation guidance to reduce the number of non-sensitive accounts on each path. By removing unnecessary privileges and memberships, teams can shrink the attack graph around sensitive entities and prevent a small compromise from becoming a privileged identity breach Use least privileged administrative role Use least privileged administrative roles in Microsoft Entra ID reduces the blast radius of a compromised admin account. In many identity attacks, adversaries first gain access through phishing, password spray, or stolen credentials, then abuse valid cloud accounts to escalate privileges, create persistence, or access sensitive data. This maps to the known attack technique Valid Accounts where an attacker uses a legitimate account’s assigned permissions instead of malware or exploits. Assigning narrow, task-specific admin roles instead of broad roles like Global Administrator limits what an attacker can do if that account is compromised and makes privilege escalation harder. Ensure Sign-in frequency is enabled and browser sessions are not persistent for Administrative users Ensure Sign-in frequency is enabled and browser sessions are not persistent for Administrative users reduces the window of opportunity after an admin session is stolen. This maps to known session-theft techniques such as Steal Web Session Cookie and Web Session Cookie, where adversaries use stolen authentication cookies to access cloud services as an already-authenticated user, sometimes bypassing MFA because the session was established before the theft. By requiring admins to reauthenticate more often and preventing persistent browser sessions, organizations make stolen sessions expire sooner and reduce the chance that a compromised admin browser session becomes long-lived access to sensitive systems. Stay ahead of attackers Attackers keep evolving, so your identity posture has to evolve with them. The strongest defense is not a one-time cleanup, it is continuously closing the gaps attackers depend on, from stolen credentials to excessive privilege and lateral movement. That is exactly what ISPM recommendations are built to help you do, turning live attacker research into clear actions you can take today. In the Microsoft Defender portal, review your ISPM recommendations, start with the five new proactive exposures, and prioritize the highest-risk attack paths first. Every path you close is one an attacker cannot take. Next steps Start by reviewing your identity security posture recommendations in the Microsoft Defender portal under Exposure management > Recommendations. Prioritize recommendations that expose privileged identities, sensitive groups, service accounts, or attack paths to critical assets, then remediate unnecessary privileges, delegated permissions, and unmanaged identity access.

Custom detections are now the unified experience for creating detections in Microsoft Defender
As we continue to deliver on our vision to simplify security workflows for the SOC, we are making custom detections the unified solution for building and managing rules over Defender XDR and Sentinel data. While analytics rules remain available, we recommend using custom detections for access to new features and enhancements. Benefits of unified custom detections Adopting custom detections as the primary method for rule management helps streamline operations and enhance security. You can refer to this page for a full list of the benefits. Some highlights include: Single experience – One interface for managing detections across all data sources, and the ability to create rules across SIEM and XDR without additional ingestion costs. Cost reduction – Write a detection combining XDR and Sentinel data without extra Sentinel ingestion costs. Faster detection – Near real-time streaming technology. Custom detection reduces Kusto cluster load and allows unlimited number of NRT rules. Built-in XDR functions – Expand functionality previously only available in XDR to use in SIEM detections, such as FileProfile(), SeenBy(), DeviceFromIP() and AssignedIPAddresses(). Native XDR remediation actions – Native XDR remediation actions are available to be configured to automatically run when a custom detection fires. The new experience for unified rules management Custom detection is the default wizard when creating a detection from advanced hunting. If your use case still requires using an analytics rule, you can click on the “create analytics rule” button from the custom detection wizard. FAQs Q: Should I stop using analytics rules? A: While we continue to build out custom detections as the primary engine for rule creation across SIEM and XDR, analytics rules may still be required in some use cases. You are encouraged to use the comparison table in our public documentation to decide if analytics rules is needed for a specific use case. No immediate action is necessary for moving existing analytics rules to detection rules. Q: Are any immediate actions required? A: No action is currently necessary. Custom detections should be used when suitable for a scenario, as we will continue to invest in new capabilities for this feature. Q: Will custom detections have feature parity with Analytics Rules? A: Yes, we are working toward parity. Learn more about adopting custom detections Please refer to our public documentation for a detailed and updated comparison. What's next?

Co-author(s): Amit Cohen and Hadar Shindler Operational technology (OT) environments are unlike anything else in cybersecurity. The systems that run our factories, power grids, water treatment plants, pipelines, and transportation networks weren’t built with modern threats in mind — and they can’t simply be patched, rebooted, or scanned the way IT systems can. A misstep doesn’t just create an alert backlog; it can stop a production line, disrupt critical services, or put physical safety at risk. To support customers in bringing their OT security solutions into their Security Operation (SOC) platform, we’re excited to announce an expansion of the Microsoft ecosystem with new OT security integrations from Dragos, Forescout, and Armis from ServiceNow. This gives customers greater flexibility to use the OT security solutions that best fit their environments. Expanding OT coverage in Defender with new partner integrations We’ve built new connectors for Dragos, Forescout and Armis that are now ready for customers to start using. Dragos "Strong OT defense starts with knowing what is running in your operational environment, the vulnerabilities those assets carry, the threats targeting your systems, and the data to determine root cause. That kind of intelligence comes from years of operating inside OT environments and tracking the groups behind those threats. As OT threats continue to grow and AI accelerates how quickly adversaries can approach the OT boundary, integrating Dragos into Microsoft Defender strengthens how organizations see, understand, and defend their OT environments." -Robert M. Lee, CEO and Co-Founder, Dragos, Inc. Forescout "Our integration with Microsoft Defender represents a significant step forward in helping organizations defend their most critical operations against today's rapidly evolving cyber threats. By combining Forescout's industry-leading visibility and protection for IoT, OT, and network-connected assets with Microsoft's leadership in endpoint, identity, cloud, and security operations, we're delivering a more unified approach to cyber defense. Together, we're enabling healthcare providers, government agencies, critical infrastructure operators, and enterprises comprehensive visibility across IT and OT environments while empowering security teams to detect, investigate, and respond to threats faster and with greater confidence." -Robert McNutt, Chief Strategy Officer, Forescout Armis “Fragmented security is no longer an option as threats to critical infrastructure evolve at machine speed. By deepening our integration with Microsoft, we are unifying visibility and context in complex OT and IoT environments. Integrating Armis Centrix™ with Microsoft Defender equips security teams with real-time, actionable insights to identify and mitigate risks across their entire operational footprint.” -Nadir Izrael, Group Vice President, Armis from ServiceNow Bringing OT and IT Security Together With these new integrations, signals, asset inventory and vulnerabilities from Dragos, Forescout, and Armis from ServiceNow flow directly into Microsoft Defender — giving security operations teams a single, unified view across IT, OT, and IoT. What this means for customers: Unified visibility across IT and OT. OT assets and vulnerabilities surface alongside IT signals in Defender, so the SOC can see and reason about them in one place. Cross-domain correlation. Identity, endpoint, cloud, and OT signals are correlated automatically. Streamlined investigation and response. Analysts can pivot from an OT detection to related IT activity (and back) without switching tools or losing context. Specialized depth, unified breadth. Customers keep the deep OT expertise of their chosen partner platform and gain the enterprise-wide coverage of Defender. Let’s take a look at some of new the user experience updates that showcase these integrations. Figure 1. Discovered devices by OT partner in device inventory The Device Inventory now will show OT devices discovered through a new partner integration (see Figure 1). Industrial assets like substation relays and switches from vendors are automatically surfaced with rich context, criticality, vendor, model, firmware, and discovery source alongside built-in recommendations to classify critical assets and protect unmanaged OT devices. The result: unified visibility across IT and OT from a single view, so security teams can find, prioritize, and protect previously unseen devices faster. Figure 2. Vulnerabilities and exposure across OT devices The Vulnerabilities view now includes a dedicated OT Partner CVEs tab, surfacing thousands of vulnerabilities on operational technology devices discovered through partner integrations. Every CVE is enriched with severity, CVSS score, age, active threats, and exposed device count, and the list is sorted by exposure so the most widespread, highest-impact risks rise to the top. Most importantly, security teams can now see OT vulnerabilities alongside IT in a single, prioritized view, making it faster to focus remediation where it matters most. Figure 3. Discovered devices exposed by OT integration Selecting a CVE opens a detail panel with a dedicated Exposed devices discovered by OT partner tab, listing every affected device along with its OS platform and last seen date. For CVE-2024-7264, that means a clear view of all 75 exposed devices in one place, from OT controllers to sales workstations. The benefit is that security teams can move from a single vulnerability straight to the exact devices at risk, making it easy to scope impact and drive targeted remediation without leaving the view. Figure 4. Discovered vulnerabilities by OT integration Drilling into a specific device, like the Substation-North-HMI2 shown here, reveals a dedicated Discovered vulnerabilities by OT partner tab alongside the standard device views such as incidents, timeline, and security recommendations. It lists every vulnerability found on that device by the OT partner, complete with severity, CVSS score, publication and detection dates, and active threats. The benefit is a complete, device-level picture of OT risk right where analysts investigate, so they can see exactly what a single asset is exposed to and prioritize remediation without switching tools or context. Built for customer choice and flexibility We’re excited to expand our integration ecosystem, giving customers the flexibility to work with the OT solutions they already trust. These integrations help bring specialized OT context into broader security workflows, enabling SOC teams, risk managers, and security leaders to collaborate more effectively while using the tools that best fit their environment. Get started The Dragos, Forescout, and Armis integrations are available in public preview starting today. Customers can enable them through the Defender portal and begin ingesting OT signals from their partner platform of choice.

For more information, see Discover local AI agents. (Preview) Local AI agent runtime protection on Windows endpoints is now available in public preview. Microsoft Defender inspects the agent loop (user prompts, tool calls, and tool responses) and can block risky activity before it executes, helping stop prompt injection and unsafe agent actions at the device level. Blocked and audited events appear as alerts in Microsoft Defender to support incident correlation and investigation workflows. The new version of the Defender deployment tool for Windows streamlines onboarding and enhances security by: Bundling the onboarding package directly into the tool's executable. Generating a key during deployment package creation that is required for running the tool. Enabling users to configure an expiry date for the package to reduce the risk of unauthorized use. In addition: You have the option of downloading the package as either an .exe or a .zip file, whichever best suits your organization's needs. A new Deployment packages page in the Defender portal facilitates management of downloaded packages by providing centralized visibility into all the packages and their current status. Now generally available: Selective Response Actions enables organizations to tailor high-impact security operations on devices during onboarding. It provides precise control over how response actions are applied on Tier-0 systems and other high-value assets, helping maintain operational stability while delivering strong protection. The new exposure score model in Defender Vulnerability Management is now generally available. This model improves risk prioritization and recommendation impact accuracy by incorporating exploit prediction data (EPSS) and asset context factors such as internet-facing status and criticality. More details here. Microsoft Secure Score now includes the Reduce unnecessary inbound internet exposure on internet-facing devices recommendation, which helps identify devices that are accessible from the public internet and may represent unnecessary attack surface. This recommendation provides centralized visibility into internet-facing devices across the environment. Many predefined SaaS application classification rules were added to the critical assets list. Have a look at our documentation for the full list. These classifications require onboarding to Microsoft Defender for Cloud Apps.Empowering SOC Analysts: Investigating Identity Threats with Microsoft Defender XDR
Identities have been a top threat vector forever. However, the rise of cloud identity attacks and an ever increasingly complex digital estate has made a tough problem even harder. Securing identities has always required a close partnership between two different functional teams – the identity and access management teams that are responsible for managing, authenticating, and authorizing user access to protected systems and data; and the security teams that detect and respond to threats across the entire digital estate. Nowhere is this more apparent than during a security incident. Let’s take a look at a common attack type like this phishing email example below: While this is a straightforward scenario, it’s still extremely effective as many organizations aren’t equipped to protect against it. The 2024 Verizon Data Breach Investigation report detailed how the median time for an attacker to access data from phishing is now just 60 seconds, giving the security team little time to triage alerts across email, identity, and endpoints, coordinate with the IAM team to disable the user and reset the password, and clean up any affected devices and inboxes. This is where implementing an integrated Identity Threat Detection and Response (ITDR) solution comes in. Our solution breaks down the existing silos between your identity and security teams by natively integrating our IAM solution, Microsoft Entra ID, and our identity threat protection solution, Microsoft Defender for Identity into our Extended Detection and Response (XDR) platform. Our ITDR offering is unique in that it delivers robust ITDR capabilities where your teams already work today. This means empowering the SOC to investigate identity alerts directly within Defender while also surfacing necessary insights from those investigations for Identity Admins directly within the Entra experience. Enhancing XDR with ITDR Identity is a core pillar of our XDR solution. Capitalizing on Microsoft’s leadership in both Identity and Access Management (IAM) and security, Defender correlates identity data and insights with Endpoint, Cloud, SaaS app and collaboration alerts to help security professionals better understand the full scope of security threats without spending hours triaging and correlating alerts. Customers benefit from the following within the Defender experience: 1. Enriched visibility across the identity fabric The ITDR dashboard provides the SOC with a single, prioritized view of Identity-specific security information and recommendations. Pulling relevant alerts and insights from across their identity footprint, this pane helps SOC teams better understand their identity posture and quickly manage potential identity-related security risks. Additionally, the recently updated identity inventory provides visibility into all the identities within their fabric including human and non-human, on-premises or in the cloud, from Microsoft or another provider. Each one of those identities also has a corresponding identity page which offers even more insights into the identity itself and allows the SOC to take action on that identity, right from the experience. 2. Proactive Identity posture and prevention The robust posture recommendations within Microsoft Security Exposure Management include Identity-specific posture recommendations (ISPM’s) that range from spotting common misconfigurations to helping customers address vulnerabilities across Active Directory, Entra ID and other common identity fabric elements, before they can be exploited. This is further enriched with attack path modeling, which provides a prioritized queue of possible attack paths that could be exploited by a threat actor. This helps the SOC and identity teams understand the entire scope of vulnerabilities—from initial access to reach critical data—and work together to prioritize the highest priority exposures. Again, because of the native integration between Entra ID and Defender the recommendations surfaced to identity admins and SOC professionals are consistent, helping the two teams work in unison to strengthen their overall identity. Defender for Identity provides dedicated sensors for Domain Controllers, Active Directory Federation Services (ADFS), Active Directory Certificate Services (AD CS) and Entra ID Connect to provide comprehensive visibility into on-premises identity environments while Entra ID does the same for cloud identities. 3. Incident-level visibility Microsoft Defender uses XDR-level detections to automatically correlate all related alerts into prioritized incidents – making it easy for analysts to see which alerts are tied to a broader incident and need to be addressed first. Incidents are automatically updated if new related alerts are triggered, so analysts can be confident they’re always looking at the latest info. Incidents are also automatically enriched with identity-related insights – like recently logged on users on an endpoint, recent activity, MFA type, open incidents, Entra ID risk level, and more—so the SOC team can quickly understand the full context of a user without needing to go hunting. All of this information is synced automatically with Microsoft Entra, ensuring both the identity and SOC teams are looking at the same data. This context is also showcased within the hunting experience. Customers can hunt for emerging threats across identity and other domains right from the same pane. 4. Automated Threats Response With attackers moving laterally in just minutes, even the best security teams will be challenged to respond in time with manual processes. Microsoft Defender utilizes AI to automatically take action on in-progress attacks and prevent lateral movement. This built-in, self-defense capability uses the correlated signals in XDR, the latest threat intelligence, and machine learning backed models to accurately predict the attack path used and block an attacker’s next move before it happens with above 99% confidence. Disruption attacks only take the minimum action necessary to stop the attacker – like disabling a compromise user or containing an affected endpoint – limiting the impact on the organization and leaving the SOC and identity teams in control to complete the investigation and bring assets back online. Security professionals can take direct action on identities right from the XDR experience through actions like “Confirm user as compromised” or “Disable user,” to mitigate an active threat. These updates are reflected automatically in the Entra portal, so they work in conjunction with Entra’s risk based conditional access. That way, when an identity is confirmed as compromised by the SOC, the risk level within Entra will automatically be raised and the relevant conditional access policies will be triggered at the next login to prevent future attacks. This signal loop protects customers both proactively through continuous monitoring and zero-trust policy engine , and reactively through real-time alerts and response from both Entra ID and Defender XDR. Conclusion In today's dynamic cyber landscape and with the complexity of modern identity environments, SOC analysts require a single pane of glass view into and the ability to effectively combat identity threats. Microsoft XDR, with its integration of Microsoft Defender for Identity and Microsoft Entra ID, provides a unified platform that enhances identity threat detection, investigation, and response capabilities, across on-prem and cloud. The seamless flow of data, alerts and workflows between IAM and Security teams created by this integration closes the loop between reactive and preventative identity protection helping organizations stay ahead of adversaries and ensure the security and integrity of their systems and data.The next frontier in endpoint security: Securing local AI agents with Microsoft Defender
AI agents are now doing real work on the endpoint — reading files, running commands, browsing the web, and acting on behalf of the users they run under. That same power is also what makes them dangerous: agents act on whatever content they take in, and much of it comes from outside the user's control — a web page, a repository, a command's output. A single malicious instruction hidden in that content can turn an agent against the very environment it's trusted to work in. With access to source code, secrets, and the corporate resources, its identity can reach — from cloud infrastructure to SharePoint, email, and internal apps — a compromised agent becomes a path to everything that identity is trusted with. Yet most security teams can't see this activity at all. Local AI agents run as ordinary processes, with little of the visibility or context SOC teams need to understand — let alone investigate — what an agent actually did. That’s why today, we're extending Microsoft Defender to secure AI agents running locally on devices. Security teams now have the visibility, context, and control needed to manage this new frontier of endpoint risk without slowing down the developers driving innovation forward. This includes: Discover 20+ types of local AI agents running on managed Windows and macOS devices Block malicious AI agent activity on the device in real time Assess local agent exposure across identities and reachable resources Investigate local AI agent activity in Advanced Hunting In preview, Defender now discovers these agents across the endpoint — AI coding agents, AI assistants, local AI runtimes, agentic IDE extensions, and Model Context Protocol (MCP) servers — and adds runtime protection for popular coding agents, with coverage expanding over time. Just as important, it brings them into the same security platform teams already use for endpoints, identities, email, and cloud, so local agents are no longer running unseen alongside the tools security teams already protect, but part of one coordinated defense. Watch this episode of the Ninja Show to see how Microsoft Defender brings visibility, context, and control to local AI agents, helping security teams securely adopt AI and stay ahead of emerging threats. Discover local AI agents on managed devices Security Operation Center (SOC) teams can now identify AI agents running locally as first-class assets, not just operating system (OS) processes. In the Defender portal, security teams can view a dedicated inventory of AI agents across their environment, spanning categories such as: Coding CLIs and terminal agents: GitHub Copilot CLI, Codex CLI, Claude Code CLI, Gemini CLI, Antigravity CLI, OpenCode Agentic IDEs and VS Code extensions: Cursor, Windsurf, Antigravity, Claude Code, Codex, Cline, Gemini, GitHub Copilot, Roo Code Desktop AI assistants: ChatGPT Desktop, Claude Desktop, Codex Desktop, Poe Desktop, Antigravity Desktop, GitHub Copilot App Local AI runtimes and autonomous platforms: OpenClaw, Nanobot, ZeroClaw, Ollama Desktop Each agent is surfaced as a security asset, with runtime context including user identity, device and process relationships, trust indicators, and integrity level. Security teams can also see configuration signals, such as “auto-approve” settings and connected services via MCP servers. Defender discovers more than 20 supported local AI agents across Windows and macOS, with coverage continuing to expand. Block malicious AI agent activity in real time Discovery is the starting point. Once SOC teams know which agents are present, they need confidence that malicious behavior will be stopped to reduce impact to their organization’s environment. For popular coding agents, Defender now provides runtime protection that helps block malicious behavior inline and in real time. This capability starts with Claude Code and GitHub Copilot CLI, with OpenClaw and OpenAI Codex coming soon. When Defender identifies that an agent activity is malicious, it can automatically block it. As with other threats, the user can be notified, and the activity is logged in the protection history. The SOC analyst receives a detailed alert with agent and session context for investigation, including details on the detected threat. At the same time, the user sees a notification on the device that the activity was blocked. The corresponding security alert in the Defender portal, with the process tree and session context for investigation Assess local agent exposure Knowing an agent exists is only half the picture. The next step is mapping the potential blast radius: the resources the agent touches, the identities it can use, and the assets exposed to its next moves. That’s why every agent discovered is automatically mapped to the device it runs on, the identity associated with that device, the MCP servers it’s connected to, and the cloud resources the identity can reach. The exposure graph turns "this agent exists" into “this agent can do these things” by providing an understanding of the agent’s connectivity across your environment. As an example, in the map below, the SOC analyst can see that a ChatGPT Desktop agent is tied to a single AWS account, and from that identity its reach extends to S3 buckets, an AWS KMS key, EC2 instances, and an AWS Bedrock agent. The agent has no cloud permissions of its own, but it inherits the account's — so if it were compromised or misused, that reach becomes a path to encrypted data and key material. This view gives security teams a clear picture of the agent's blast radius, so they can decide how to contain it before it's abused. Investigate local AI agent activity in Advanced Hunting Beyond the inventory and exposure views, security teams often need to hunt across the environment — to ask which agents are behaving unusually, and what else they touch. Every AI agent discovery event, MCP server connection, and configuration signal is queryable in Advanced Hunting, alongside the endpoint, identity, email, and cloud security telemetry your team already uses every day. This capability unlocks two use cases that security teams have been asking for: Correlate agent activity with process, file, network, identity, and cloud telemetry to see the full picture of what the agent did Hunt for risky configurations – for example, agents running in auto-approve mode under an identity with privileged access to production, source code, or CI/CD systems Security teams can turn any of these queries into a custom detection rule — for instance, raising an alert whenever a newly discovered agent appears with a risky configuration on a device tied to a privileged identity. Securing the next frontier of endpoint activity The risk that opened this post — an agent acting on a malicious instruction and reaching everything its identity can touch — is exactly what this protection is built to contain. By bringing local AI agents into the same platform teams already use for endpoints, identities, and cloud, Defender turns that blind spot into something security teams can see, investigate, and stop — without getting in the developer's way. Developers keep the AI tools accelerating their work. Defenders get the visibility and real-time protection to stay ahead of attackers as they turn to this new surface. That balance — speed for builders, control for defenders — is what securing the AI era actually requires.

Managing security across many tenants shouldn’t mean drowning in a single, flat list. We’re excited to share a new capability, now in public preview in the Microsoft Defender multitenant (MTO) portal: Tenant Groups—a flexible way to organize the tenants you manage and switch your view between them with a single click. If you’re a managed security service provider (MSSP), a cloud service provider (CSP), or a security team operating across multiple Entra ID tenants, this one’s for you. What’s new Tenant Groups let you create logical groupings of tenants (by customer segment, geography, criticality, onboarding stage—whatever fits how you work) and seamlessly switch the Defender MTO view to show data from only the tenants in that group. NOTICE: The feature previously called Tenant groups—used for content distribution—has been renamed to Deployment profiles. The name “Tenant Groups” now refers to this new grouping experience. Why it matters Focus, faster – Investigate incidents, hunt threats, and review posture against just the tenants you care about right now—without noise from the rest. Operational clarity – Group tenants the way your team actually works (e.g., Tier 1 customers, EMEA, Pilot rollout). Permissions-aware – Even if a Tenant Group contains more tenants, you’ll only see the ones where you have B2B/GDAP (granular delegated admin privileges) access. Your existing access controls stay in charge. Permissions you’ll need To work with Tenant Groups, your account needs one of the following: Entra ID roles Security Administrator Security Operator Global Administrator Product-specific (MDE, MDI, etc.) role-based access control (RBAC) Global Administrator Security Administrator Plus, any custom RBAC roles required to see data across products Unified RBAC (URBAC) Security/read—to view Tenant Groups Security/manage—to create Tenant Groups Remember: A Tenant Group can include tenants you don’t have access to. You’ll only ever see the ones your permissions allow. Getting started 1. Open Tenant Groups Sign in to the Microsoft Defender portal with administrative credentials, then navigate to Multitenant Management > Tenant Groups. You’ll find a built-in group called My private group that contains all the tenants from your previous setup. You can add or remove tenants from it, but it can’t be deleted. 2. Create a Tenant Group Select + Create tenant group. Give it a descriptive name (e.g., Healthcare customers, EMEA Tier 1). Optionally, add a description so teammates know the group’s intent. Select the tenants you want to include. That’s it—your group is ready. 3. Switch between Tenant Groups In the top-left corner of the portal, select Open multitenant management. Choose the group you just created. Navigate around the Defender MTO portal—incidents, alerts, devices, hunting—and you’ll see only data from the tenants in that group. Switch groups anytime to refocus. Live change detection: If a teammate edits a Tenant Group (adds or removes tenants) while you’re viewing it, the portal surfaces a notification so you know the underlying scope has changed. No stale views, no surprises. 4. Edit a Tenant Group Go back to Multitenant Management > Tenant Groups. Select the group and choose Edit. Add or remove tenants as your environment evolves, then re-test your views. Tips for getting the most out of Tenant Groups Start with how your team triages – Name groups after the workflows you actually run (On-call queue, Customer A—production). Keep groups small and purposeful – Overlapping, focused groups beat one giant catch-all. Pair with Deployment profiles – Use Tenant Groups for viewing, and Deployment profiles for distributing content—two clean, complementary concepts. Audit access regularly – Because group membership is independent of B2B/GDAP access, periodic reviews keep expectations aligned. We want your feedback Tenant Groups are designed around real multitenant operations work—and we’d love to hear how you’re using them. Try it out in your environment, share what’s working (and what isn’t), and let us know what you’d like to see next.Monthly news - January 2026

Cybersecurity has entered an era of relentless complexity. As threat actors increasingly leverage artificial intelligence to automate attacks, evade detection, and scale their tactics, defenders are challenged to keep up. In this new era, security operations centers (SOCs) must transform to not just react, but to anticipate, disrupt, and outpace the next wave of cyberthreats. Microsoft’s goal is to empower every organization to meet this challenge head-on by transforming how security operates. We believe the future of the SOC is more than just agentic: it’s predictive and proactive. This means moving beyond fragmented tools and manual processes, and instead embracing a unified, intelligent approach where AI-driven skills and agents work in concert with human expertise. To bring this vision to life, it’s essential to look at the SOC through the lens of its lifecycle—a dynamic continuum that spans from anticipation and prevention through to recovery and optimization—and to recognize the unique challenges and opportunities within each stage. With Security Copilot’s GenAI and agentic capabilities woven across this lifecycle, Microsoft is delivering an integrated defense platform that enables defenders to move faster, act smarter, and stay ahead of adversaries. Introducing agentic innovation across the SOC lifecycle At Ignite, our agentic innovations are concentrated in three of the five SOC lifecycle pillars, and each one represents a leap forward in how analysts anticipate, detect, triage and investigate threats. Predict and prevent Threat Intelligence Briefing Agent: Introduced in March, this agent has already helped security teams move from reactive to anticipatory defense. At Ignite, we’re announcing that the Threat Intelligence Briefing Agent is now fully embedded in the Microsoft Defender portal, delivering daily, tailored briefings that synthesize Microsoft’s unparalleled global intelligence with organization-specific context in just minutes. Teams no longer need to spend hours gathering TI from disparate sources—the agent automates this process, offering the most current and relevant insights. Analysts can reference the summary to prioritize action, using the agent’s risk assessments, clear recommendations, and links to vulnerable assets to proactively address exposures. Detect and disrupt Dynamic Threat Detection Agent: Detections have long been bottlenecked by the limitations of traditional alerting systems, which rely on predefined logic that can’t scale fast enough to match the speed and variability of modern attacks— resulting in blind spots and missed threats. The Dynamic Threat Detection Agent addresses this challenge head-on. Instead of depending on static rules or isolated input, it continuously analyzes incidents and telemetry, searching for gaps in coverage and correlating signals across the entire security stack. For example, this is how it surfaced a recent AWS attack: a threat actor used an EntraID account to federate into an AWS admin account to exfiltrate sensitive data. The Dynamic Threat Detection Agent generated an alert before the intruder even authenticated into the single sign-on flow, driven by a correlated signal from Sentinel. That alert didn’t exist beforehand; the agent created it on the fly to stop the attack. The result is an adaptive system that extends Microsoft’s industry-leading, research-based detections with context-aware alerts tailored to each organization, closing gaps and revealing threats that legacy systems miss. Triage and investigate Security Alert Triage Agent (previously named Phishing Triage Agent): In March 2025, we introduced the Security Alert Triage Agent, built to autonomously handle user-submitted phishing reports at scale. The agent classifies incoming alerts and resolves false positives, escalating only the malicious cases that require human expertise. At Microsoft Ignite, we’re announcing its general availability, backed by strong early results: the agent identifies 6.5 times more malicious alerts, improves verdict accuracy by 77%, and frees analysts to spend 53% more time investigating real threats. St. Luke’s even said it’s saving their team nearly 200 hours each month. Coming soon, we’ll be extending these autonomous triage capabilities beyond phishing to identity and cloud alerts, bringing the same precision and scale to more SOC workflows. Note: The Phishing Triage Agent has since been expanded and is now called the Security Alert Triage Agent. Learn more at aka.ms/SATA Threat Hunting Agent: this agent reimagines the investigation process. Instead of requiring analysts to master complex query languages or sift through mountains of data, Threat Hunting Agent enables natural language investigations with contextual insight. Analysts can vibe with the agent by asking questions in plain English, receive direct answers, and be guided through comprehensive hunting sessions. It levels up the existing Security Copilot NL2KQL capability by enabling teams to explore patterns, pivot intuitively and uncover hidden signals in real time for a fluid, context-aware experience. This not only accelerates investigations but makes advanced threat hunting accessible to every member of the SOC, regardless of experience level. Agents built into your workflows To make the agents easily accessible and help security teams get started more quickly, we are excited to announce that Security Copilot will be available to all Microsoft 365 E5 customers. Rollout starts today for existing Security Copilot customers with Microsoft 365 E5 and will continue in the upcoming months for all Microsoft 365 E5 customers. Customers will receive 30-day advanced notice before activation. Learn more: https://aka.ms/SCP-Ignite25 Discover more: the Security Store The Security Store, now generally available, is the central hub for discovering, deploying, and managing first-party and third-party security agents. Today, it provides instant access to 20+ agents deployable directly in the Microsoft Defender portal, all within a broader ecosystem of 100+ trusted security solutions. Whether you're investigating incidents, hunting threats, or automating response, the Security Store extends Defender with vetted, scenario-aligned tools that can be set up in minutes. Learn more in this blog. Introducing new GenAI embedded capabilities Security Copilot isn’t just growing through agents—it’s also gaining new embedded capabilities: GenAI skills that help SOC teams work faster, operate at greater scale, and get upleveled directly inside Microsoft Defender. Today, we’re excited to introduce new innovations: Analyst Notes represent a meaningful shift in how investigation work is captured and shared. For organizations that choose to opt into this capability, Copilot automatically reconstructs an analyst’s investigation session—from the moment they open an incident to the moment they close it—and turns that activity into clear, structured notes. The system can even track multiple sessions in parallel and attribute actions to the right incident, and analysts can fully review and edit the generated notes before saving them. This not only saves teams valuable time and effort, it preserves the actual investigation path with far greater accuracy and consistency than manual documentation ever could. The result is a living, cumulative record of how the SOC investigates threats: easier handoffs, stronger auditability, faster onboarding, and a deeper shared understanding of how incidents unfold across multiple SecOps members and phases. Standard Operating Procedures (SOPs) for guided response allows organizations to upload their own internal procedures so Security Copilot can align its recommendations with established guidebooks and compliance requirements. Guided response is one of the ways Copilot helps analysts navigate an incident: it offers one-click actions across triage, containment, investigation and remediation that teams can take immediately. With SOPs uploaded, these recommendations draw directly from organizational workflows and policy standards, ensuring they are contextually relevant and trusted. For defenders, this translates into greater confidence and faster, more consistent decision-making. We’re also eager to share that we’re introducing auto-generated content configuration for Security Copilot’s incident summaries. This new feature allows security admins to decide how and when summaries are produced, choosing between always auto-generating, manual trigger only, or auto-generating based on incident severity. The configuration is managed directly in the Microsoft Defender portal, giving organizations flexibility to fine-tune Copilot’s outputs to their operational needs.
