How to stop incidents merging under new incident (MultiStage) in defender.
Dear All We are experiencing a challenge with the integration between Microsoft Sentinel and the Defender portal where multiple custom rule alerts and analytic rule incidents are being automatically merged into a single incident named "Multistage." This automatic incident merging affects the granularity and context of our investigations, especially for important custom use cases such as specific admin activities and differentiated analytic logic. Key concerns include: Custom rule alerts from Sentinel merging undesirably into a single "Multistage" incident in Defender, causing loss of incident-specific investigation value. Analytic rules arising from different data sources and detection logic are merged, although they represent distinct security events needing separate attention. Customers require and depend on distinct, non-merged incidents for custom use cases, and the current incident correlation and merging behavior undermines this requirement. We understand that Defender’s incident correlation engine merges incidents based on overlapping entities, timelines, and behaviors but would like guidance or configuration best practices to disable or minimize this automatic merging behavior for our custom and analytic rule incidents. Our goal is to maintain independent incidents corresponding exactly to our custom alerts so that hunting, triage, and response workflows remain precise and actionable. Any recommendations or advanced configuration options to achieve this separation would be greatly appreciated. Thank you for your assistance. Best regards
Transforming Security Analysis into a Repeatable, Auditable, and Agentic Workflow
Author(s): Animesh Jain, Vinay Yadav Shaped by investigations into the strategic question of what it takes for Windows to achieve world-leading security—and the practical engineering needed to explore agentic workflows at scale and their interfaces. Our work in Windows Servicing & Delivery (WSD) is shaped by two guiding prompts from leadership: "what does it take for Windows to achieve world-leading security", and "how do we responsibly integrate AI into systems as large and high-churn as Windows?". Reasoning models open new possibilities on both fronts. As we continue experimenting, one issue repeatedly surfaces as the bottleneck for scalable security assurance: variant vulnerabilities. They are subtle, recurring, and easy to miss—making them an ideal proving ground for the enterprise-grade workflow we present here. Security Analysis at Windows Scale Security analysis shouldn’t be an afterthought—it should be a continuous, auditable, and intelligence-driven process built directly into the engineering workflow. This work introduces an agentic security analysis pipeline that uses reasoning models and tool-based agents to detect variant vulnerabilities across large, fast-changing codebases. By combining automation with explainability, it transforms security validation from a manual, point-in-time task into a repeatable and trustworthy part of every build. Why are variants the hard part? Security flaws rarely occur in isolation. Once a vulnerability is fixed, its logical or structural pattern often reappears elsewhere in the codebase—hidden behind different variables, layers, or call paths. These recurring patterns are variants—the quiet echoes of known issues that can persist across millions of lines of code. Finding them manually is slow, repetitive, and incomplete. As engineering velocity increases, so does the likelihood of variant drift—the same vulnerability class re-emerging in a slightly altered form. Each missed variant carries a downstream cost: regression, re-servicing, or, in the worst cases, re-exploitation. Modern large systems like Windows are too large, too interconnected, and ship too frequently for manual vulnerability discovery to keep pace. Traditional static analyzers and deterministic class-based scanners struggle to generalize these patterns or create too much noise, while targeted fuzzing campaigns often fail to trigger the nuanced runtime conditions that expose them. To stay ahead, automation must evolve. We need systems that reason—not just scan—systems capable of understanding relationships between code regions and applying logical analogies instead of brute-force enumeration. Reasoning Models: A Turning Point in Security Research Recent advances in AI reasoning have demonstrated that large language models can uncover vulnerabilities previously missed by deterministic tools. For example, Google’s Big Sleep agent surfaced an exploitable SQLite flaw (CVE-2025-6965) that bypassed traditional fuzzers due to configuration-sensitive logic. Similarly, an o-series reasoning model helped identify a critical Linux SMB logoff use-after-free (CVE-2025-37899), proving that reasoning-driven automation can detect complex, context-dependent flaws in mature kernel code. These breakthroughs show what’s possible when systems can form, test, and refine hypotheses about software behavior. The challenge now is scaling that intelligence into repeatable, auditable, enterprise-grade workflows—where every result is traceable, reviewable, and integrated into the developer’s daily workflow. A Framework for Agentic Security Analysis To address this challenge, we’ve developed an agentic security analysis framework that applies reasoning models within structured, enterprise grade workflow pattern. It combines large language model agents, specialized analysis tools, and structured artifact generation to make vulnerability discovery continuous, explainable, and auditable. It is interfaced as a first-class Azure DevOps (ADO) pipeline and can be integrated natively into enterprise CI/CD processes. For security analysis, it continuously reasons over large, evolving codebases to identify and validate variant vulnerabilities earlier in the release cycle. Together, these components form a repeatable workflow that helps surface variant patterns with greater consistency and clarity. Core Technical Pillars Scale – Autonomous Code Reasoning Long-context models extend analysis across massive, evolving codebases. They infer analogies, relationships, and behavioral patterns between code regions, enabling scalable reasoning that adapts as systems grow. Tool–Agent Collaboration Specialized agents coordinate to perform semantic search, graph traversal, and both static and dynamic interpretation. This distributed reasoning approach ensures resilience and precision across diverse enterprise environments. Structured Artifact Generation Every step produces versioned, auditable artifacts that document the reasoning process. These artifacts help provide reproducibility, compliance, and transparency—critical for enterprise governance and regulated industries. Together, these pillars enable scalable, explainable, and repeatable vulnerability discovery across large software ecosystems such as Windows. Every stage—from reasoning to validation—is logged and traceable, designed to make each discovery reproducible and reviewable. Inside the framework Agent-Led, Human-Reviewed The system is agent-led from start to finish and human-reviewed only at decision boundaries. Agents form hypotheses from recent fixes or vulnerability classes, test them against context, perform validation passes, and generate evidence-backed reports for reviewer confirmation. The workflow mirrors how seasoned security engineers operate—only faster and continuously. n tasks based on templatized prompts. Tool Specialists as Agents Each analytical tool functions as a domain-specific agent—performing semantic search, file inspection, or function-graph traversal. These agents collaborate through structured orchestration, maintaining specialization without sacrificing coherence. Agentic Patterns and Orchestration The framework employs reusable reasoning patterns—reflective reasoning, actor–validator loops, and parallel tool dialogues—for accuracy and scale. A central conductor agent governs task coordination, context flow, and artifact persistence across runs. Auditability Through Artifacts Every investigation yields a transparent chain of artifacts: Analysis Notes – summarize candidate issues Critique Notes – document reasoning and counter-evidence Synthesis Reports – provide developer-ready summaries, diffs, call graphs, and exploitability insights Agentic Conversation Logs - provides conversation logs so developers can backtrack on reasoning and get more context This structure makes each discovery fully traceable and auditable. CI/CD-Native Integration The interface operates as a first-class Azure DevOps pipeline, attachable to pull requests, nightly builds, or release triggers. Each run publishes versioned artifacts and validation notes directly into the developer workflow—making reasoning-driven security a seamless part of software delivery. What It Can Do Today Seeded Variant Hunts: Start from a recent fix or known pattern to enumerate analogous cases, analyze helper functions, and test reachability. Evidence-First Reporting: Every finding includes reproducible evidence—code snippets, diffs, and caller graphs—delivered within the PR or work item. Scalable Coverage: Runs across servicing branches, producing consistent and auditable validation artifacts. Improved Precision: A reasoning-based validation pass has significantly reduced false positives in internal testing. Case Study: CVE-2025-55325 During a sweep of “*_DEFAULTS” deserializers, the agentic pipeline independently identified GetPoolDefaults trusting a user-controlled size field and copying that many bytes from a caller buffer. The missing runtime bounds check—guarded only by an assertion in debug builds—enabled a potential read access violation and information disclosure. The mitigation mirrored a hardened sibling helper: enforcing runtime bounds on Size versus BytesAvailable/Version before allocation and copy. The finding was later validated by the servicing teams, confirming it matched an issue already under active investigation—illustrating how the automated reasoning process can independently surface real-world vulnerabilities that align with expert analysis. Beyond Variant Analysis The underlying architecture of this framework extends naturally beyond variant detection: Net-new vulnerability discovery through cross-binary pattern matching Model-assisted fuzzing & static analysis orchestrated through CI/CD integration Regression detection via historical code comparisons Security Development Lifecycle (SDL) enforcement and reproducibility checks The agentic patterns and tooling can support net-new vulnerability discovery through cross-binary pattern matching, regression detection using historical code comparisons, reproducibility checks aligned with SDL requirements, and model-assisted fuzzing orchestrated through CI/CD processes. These capabilities open the door to applying reasoning-driven workflows across a broader range of security & validation tasks. The Road Ahead Looking ahead, this trajectory naturally leads toward autonomous cybersecurity pipelines powered by reasoning agents that apply reflective analysis, validation loops, and structured tool interactions to complex codebases. By structuring each step as an auditable artifact, the approach supports security & validation analysis that is both explainable and repeatable. These agents could help validate security posture, analyze historical and real-time signals, and detect anomalous patterns early in the lifecycle.

These solutions integrate with Microsoft Security products to complete end-to-end workflows, helping customers improve their security” Within the Microsoft Defender portal, SOC teams can now discover Copilot agents from both Microsoft and partners in the embedded Security Store, and run them all from a single, familiar interface. Let’s look at an example of how these agents might help in the day of the life of a SOC analyst. The day starts with Watchtower (BlueVoyant) confirming Sentinel connectors and Defender sensors are healthy, so investigations begin with full visibility. As alerts arrive, the Microsoft Defender Copilot Alert Triage Agent groups related signals, extracts key evidence, and proposes next steps; identity related cases are then validated with Login Investigator (adaQuest), which baselines recent sign-in behavior and device posture to cut false positives. To stay ahead of emerging campaigns, the analyst checks the Microsoft Threat Intelligence Briefing Agent for concise threat rundowns tied to relevant indicators, informing hunts and temporary hardening. When HR flags an offboarding, GuardianIQ (People Tech Group) correlates activity across Entra ID, email, and files to surface possible data exfiltration with evidence and risk scores. After containment, Automated Closing Comment Generator (Ascent Global Inc.) produces clear, consistent closure notes from Defender incident details, keeping documentation tight without hours of writing. Together, these Microsoft and partner agents maintain platform health, accelerate triage, sharpen identity decisions, add timely threat context, reduce insider risk blind spots, and standardize reporting—all inside the Defender portal. You can read more about the new agents available in the Defender portal in this blog. In addition, Security Store is now integrated into Microsoft Entra, focused on identity-centric solutions.

In today’s AI-powered world, the boundaries of security are shifting fast. From code to runtime, organizations are moving faster than ever – building with AI across clouds, accelerating innovation, and expanding the landscape defenders must protect. Security teams are balancing fragmented tools, growing complexity and a new generation of intelligent, agentic systems that learn, adapt and act across the digital estate. The challenge isn’t understanding the change – it’s staying ahead of it. At Ignite 2025, we’re unveiling four major advancements in Microsoft Defender for Cloud that redefine how security keeps pace with cloud-scale innovation and AI autonomy. Together, they advance a simple idea – that security should move as fast as the systems it protects, adapting in real time to new patterns of risk. Defender for Cloud + GitHub Advanced Security integration delivers AI-driven, automated remediation We start where every application does: in the code – and with a major step forward in how security and development teams work together. The pace of development has scaled dramatically. Organizations now build more than 500 new apps 1 on average each year – and as code volume grows, the gap between development and security widens. Working in separate tools with no shared context, developers can’t see which threats security teams prioritize, and security teams can’t easily trace issues back to their source in code. To help organizations address this challenge, Microsoft Defender for Cloud now natively integrates with GitHub Advanced Security (in public preview) – the first native link between runtime intelligence and developer workflows, delivering continuous protection from code to runtime. This bidirectional integration brings Defender for Cloud’s runtime insights directly into GitHub, so vulnerabilities can be surfaced, prioritized, and remediated with AI assistance – all within the developer environment. When Defender for Cloud detects a critical vulnerability in a running workload, developers see exactly where the issue originated in code, how it manifests in production, and the suggestion of how to fix the vulnerability. With Copilot Autofix and GitHub Copilot coding agent capabilities, AI-generated and validated fixes are suggested in real time – shortening remediation cycles from days to hours. For organizations, this integration delivers three tangible benefits: Collaborate without friction. Security teams can open and track GitHub issues directly from Defender for Cloud with context and vulnerability details, ensuring shared visibility between security and development. Accelerate remediation with AI. Copilot-assisted fixes make it faster and safer to resolve vulnerabilities without breaking developer flow. Prioritize what matters most. By mapping runtime threats directly to their source in code, teams can focus on vulnerabilities that are truly exploitable – not just theoretical. Together, security, development, and AI now move as one, finding and fixing issues faster and creating a continuous feedback loop that learns from runtime, feeds insights back into development, and redefines how secure apps and agents get built in the age of AI. Unified posture management and threat protection extends to secure AI Agents The next frontier is securing the AI agents teams create – ensuring protection evolves as fast as the intelligence driving them. IDC projects that organizations will deploy 1.3 billion AI agents by 2028 2 , each capable of reasoning, acting, and accessing sensitive data across multiple environments. As these systems scale, visibility becomes the first challenge: knowing what agents exist, what data they touch, and where risks connect. And with 66% of organizations 3 planning to establish a formal AI risk management function within the next four years, it’s clear that security leaders are racing to catch up with this next evolution. To help organizations stay ahead, Microsoft Defender now provides unified posture management and threat protection for AI agents as a part of Microsoft Agent 365 (in preview). These first-of-its-kind capabilities that secure agentic AI applications across their entire lifecycle. With this innovation, Defender helps organizations secure AI agents in three critical ways: Comprehensive visibility for AI Agents. Gain unified visibility and management of AI agents through Defender, spanning both pro-code and low-code environments from Microsoft Foundry to Copilot Studio. With a single agent inventory, teams can see where agents run and what they connect to – reducing shadow AI and agent sprawl. Risk reduction through posture management. Proactively strengthen AI agents’ security posture with Defender’s posture recommendations and attack path analysis for AI agents. These insights reveal how weak links across agents and cloud resources can form broader risks, helping teams detect and address vulnerabilities before they lead to incidents. Threat protection for AI Agents. Detect, investigate, and respond to threats targeting agentic AI services across models, agents from Microsoft Copilot Studio and Microsoft Foundry, and cloud applications using Defender’s AI-specific detection analytics. These include scenarios like prompt injection, sensitive data exposure, or malicious tool misuse, all enriched with Microsoft’s unmatched threat intelligence for deeper context and faster response. By embedding security into every layer of the agentic AI lifecycle, Defender helps organizations start secure and stay secure. This unified approach ensures that as AI agents evolve and scale, protection scales with them, anchoring the same continuous security foundation that extends across code, cloud, and beyond. Cloud posture management extends to secure serverless resources Defender for Cloud’s unified foundation extends beyond agents – to the cloud infrastructure and platforms that power them – rounding out the protection that scales with innovation itself. That innovation is increasingly running on serverless computing, now a core layer of cloud-native and AI-powered application development. It gives teams the speed and simplicity to deliver faster, but also expands the attack surface across multicloud environments with new exposure points, from unsecured functions to lateral movement risks. To help organizations secure this expanding layer, Microsoft Defender for Cloud is extending its Cloud Security Posture Management (CSPM) to serverless compute and application platforms (available in preview by end of November). With this new coverage, security teams gain greater visibility into serverless compute environments and application platforms, including Azure Functions, Azure Web Apps, and AWS Lambda. Defender for Cloud integrates serverless posture insights into attack path analysis, helping security teams identify and visualize risk, continuously monitor and detect misconfigurations, and find vulnerable serverless resources – further strengthening security posture across the modern application lifecycle. This extension brings serverless computing into the same unified protection model that already secures code, containers, and workloads in Defender for Cloud. As customers modernize with event-driven architectures, Defender for Cloud evolves with them, delivering consistent visibility, control, and protection across every layer of the cloud. Deeper expansion into the Defender Portal turns fragmentation into focus Finally, bringing all the signals security teams depend on into one place requires a single operational hub – a unified security experience that delivers clarity at scale. Yet with 89% of organizations operating across multiple clouds 4 and using an average of 10 security tools to protect them 5 , teams struggle to manage risk across fragmented dashboards and disjointed data – slowing detection and response and leaving blind spots that attackers can exploit. To help security teams move faster and act with clarity, we’re announcing the public preview of unified cloud security posture management into the Microsoft Defender security portal. With Microsoft Defender for Cloud’s deep integration into the unified portal, we eliminate security silos and bring a modern, streamlined experience that is more intuitive and purpose-built for today’s security teams. With this deep integration, Microsoft delivers three key advancements: A new Cloud Security dashboard that unifies posture management and threat protection, giving security teams a complete view of their multicloud environment in one place. Integrated posture capabilities within Exposure Management. Security teams can now see assets, vulnerabilities, attack paths, secure scores, and prioritized recommendations in a single pane of glass, focusing on the issues that matter most. A centralized asset inventory that consolidates resources across Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP), enabling posture validation, logical segmentation, and simplified visibility aligned to operational needs. To complement these capabilities, granular role-based access control (RBAC) helps reduce operational risk and simplify compliance across multicloud environments. The Microsoft Defender portal is now the center of gravity for security teams – bringing together cloud, endpoint and identity protection into one connected experience. Looking ahead, customers will soon be able to onboard and secure new resources directly within the Defender portal, streamlining setup and accelerating time to value. Large organizations will also gain the ability to manage multiple tenants from this unified experience as the rollout expands. The Azure portal remains essential for Defender for Cloud personas beyond security teams, such as DevOps. Adding new resource coverage will continue in the Azure portal as part of this transition. We’ll also keep enhancing experiences for IT and operations personas as part of our broader vision, read more on that in the latest news here. Ready to explore more?

The goal is to avoid manual changes and ensure compliance from day one. Current Setup: I’ve used the built-in policy: Configure Microsoft Defender for Servers plan, which successfully enables: Defender for Cloud Plan P2 Endpoint Protection Agentless scanning I attempted to copy this policy and add parameters for Vulnerability Assessment, but the assignment fails with an error. What I’ve Tried: For File Integrity Monitor: Policy name → Configure ChangeTracking Extension for Windows virtual machines For Vulnerability Assessment: Policy name → Configure machines to receive a vulnerability assessment provider Assigning these policies works on my non-prod subscription, but the toggle in Defender for Cloud → Environment Settings remains No. Challenge: How can I ensure these options (File Integrity Monitoring, Vulnerability Assessment, and preferably Guest Configuration Agent) are automatically enabled for: All existing subscriptions Any new subscriptions created in the future Goal: No manual intervention in Defender for Cloud portal Fully automated via Azure Policy or another recommended approach uestions: Is there a way to extend the built-in policy or create a custom initiative that enforces these settings at the subscription level? Are there ARM templates, Bicep modules, Powershell scripts or REST API calls that can toggle these settings programmatically? Any best practices for ensuring compliance across multiple subscriptions? Any help is much appreciated and looking forward to your expertise! Thank you in advance. Best Regards, Pascal Slot
XDR advanced hunting region specific endpoints
Hi, I am exploring XDR advanced hunting API to fetch data specific to Microsoft Defender for Endpoint tenants. The official documentation (https://learn.microsoft.com/en-us/defender-xdr/api-advanced-hunting) mentions to switch to Microsoft Graph advanced hunting API. I had below questions related to it: 1. To fetch the region specific(US , China, Global) token and Microsoft Graph service root endpoints(https://learn.microsoft.com/en-us/graph/deployments#app-registration-and-token-service-root-endpoints ) , is the recommended way to fetch the OpenID configuration document (https://learn.microsoft.com/en-us/entra/identity-platform/v2-protocols-oidc#fetch-the-openid-configuration-document) for a tenant ID and based on the response, the region specific SERVICE/TOKEN endpoints could be fetched? Since using it, there is no need to maintain different end points for tenants in different regions. And do we use the global service URL https://login.microsoftonline.com to fetch OpenID config document for a tenantID in any region? 2. As per the documentation, Microsoft Graph Advanced hunting API is not supported in China region (https://learn.microsoft.com/en-us/graph/api/security-security-runhuntingquery?view=graph-rest-1.0&tabs=http). In this case, is it recommended to use Microsoft XDR Advanced hunting APIs(https://learn.microsoft.com/en-us/defender-xdr/api-advanced-hunting) to support all region tenants(China, US, Global)?
Update content package Metadata
Hello Sentinel community and Microsoft. Ive been working on a script where i use this command: https://learn.microsoft.com/en-us/rest/api/securityinsights/content-package/install?view=rest-securityinsights-2024-09-01&tabs=HTTP Ive managed to successfully create everything from retrieving whats installed, uninstalling, reinstalling and lastly updating (updating needed to be "list, delete, install" however :'), there was no flag for "update available"). However, now to my issue. As this work like a charm through powershell, the metadata and hyperlinking is not being deployed - at all. So i have my 40 content packages successfully installed through the REST-api, but then i have to visit the content hub in sentinel in the GUI, filter for "installed" and mark them all, then press "install". When i do this the metadata and hyperlinking is created. (Its most noticeable that the analytic rules for the content hubs are not available under analytic rules -> Rule templates after installing through the rest api). But once you press install button in the GUI, they appear. So i looked in to the request that is made when pressing the button. It uses another API version, fine, i can add that to my script. But it also uses 2 variables that are not documented and encrypted-data. they are called c and t: Im also located in EU and it makes a request to SentinelUS. im OK with that, also as mentioned, another API version (2020-06-01) while the REST APi to install content packages above has 2024-09-01. NP. But i can not simulate this last request as the variables are encrypted and not available through the install rest api. They are also not possible to simulate. it ONLY works in the GUI when pressing install. Lastly i get another API version back when it successfully ran through install in GUI, so in total its 3 api versions. Here is my code snippet i tried (it is basically a mimic of the post request in the network tab of the browser then pressing "install" on the package in content hub, after i successfully installed it through the official rest api). function Refresh-WorkspaceMetadata { param ( [Parameter(Mandatory = $true)] [string]$SubscriptionId, [Parameter(Mandatory = $true)] [string]$ResourceGroup, [Parameter(Mandatory = $true)] [string]$WorkspaceName, [Parameter(Mandatory = $true)] [string]$AccessToken ) # Use the API version from the portal sample $apiVeri = "?api-version=" $RefreshapiVersion = "2020-06-01" # Build the batch endpoint URL with the query string on the batch URI $batchUri = "https://management.azure.com/\$batch$apiVeri$RefreshapiVersion" # Construct a relative URL for the workspace resource. # Append dummy t and c parameters to mimic the portal's request. $workspaceUrl = "/subscriptions/$SubscriptionId/resourceGroups/$ResourceGroup/providers/Microsoft.OperationalInsights/workspaces/$WorkspaceName$apiVeri$RefreshapiVersion&t=123456789&c=dummy" # Create a batch payload with several GET requests $requests = @() for ($i = 0; $i -lt 5; $i++) { $requests += @{ httpMethod = "GET" name = [guid]::NewGuid().ToString() requestHeaderDetails = @{ commandName = "Microsoft_Azure_SentinelUS.ContenthubWorkspaceClient/get" } url = $workspaceUrl } } $body = @{ requests = $requests } | ConvertTo-Json -Depth 5 try { $response = Invoke-RestMethod -Uri $batchUri -Method Post -Headers @{ "Authorization" = "Bearer $AccessToken" "Content-Type" = "application/json" } -Body $body Write-Host "[+] Workspace metadata refresh triggered successfully." -ForegroundColor Green } catch { Write-Host "[!] Failed to trigger workspace metadata refresh. Error: $_" -ForegroundColor Red } } Refresh-WorkspaceMetadata -SubscriptionId $subscriptionId -ResourceGroup $resourceGroup -WorkspaceName $workspaceName -AccessToken $accessToken (note: i have variables higher up in my script for subscriptionid, resourcegroup, workspacename and token etc). Ive tried with and without mimicing the T and C variable. none works. So for me, currently, installing content hub packages for sentinel is always: Install through script to get all 40 packages Visit webpage, filter for 'Installed', mark them and press 'Install' You now have all metadata and hyperlinking available to you in your Sentinel (such as hunting rules, analytic rules, workbooks, playbooks -templates). Anyone else manage to get around this or is it "GUI" gated ? Greatly appreciated.Detecting browser anomalies to disrupt attacks early
