Every data security investigation starts with the same question: What data security risks are buried in this data? Exposed credentials in thousands of files across a data estate. Evidence of fraud hidden in vendor communications. Sensitive documents accidentally shared to a large group. Finding these risks manually — reviewing content file by file, message by message — is no longer viable when organizations are managing 220 zettabytes of data[1] and facing over 12,000 confirmed breaches annually[2]. That's why we built Microsoft Purview Data Security Investigations, now generally available. Microsoft Purview Data Security Investigations enables data security teams to identify investigation-relevant data, investigate that data with AI-powered deep content analysis, and mitigate risk — all within one unified solution. Teams can quickly analyze data at scale to surface sensitive data and security risks, then collaborate securely to address them. By streamlining complex, time‑consuming investigative workflows, admins can resolve investigations in hours instead of weeks or months. Proactive and reactive investigation scenarios Organizations are using Data Security Investigations to tackle diverse data security challenges — from reactive incident response to proactive risk assessment. Some of our top use cases from preview include: Data breach and leak: Understand severity, sensitivity, and significance of data that has been leaked or breached, including risks buried in impacted data, to take action and mitigate its impact to the organization. Credentials exposure: Proactively scan thousands of SharePoint sites to identify files containing credentials like passwords, which can give a threat actor prolonged access to an organization's environment. Internal fraud and bribery: Uncover suspicious communications tied to vendor payments or client interactions, uncovering hard-to-find patterns in large volumes of emails and messages. Sensitive data exposure in Teams: Determine who accessed classified documents after accidental sharing — and whether that data was further distributed. Inappropriate content investigations: Quickly find what was posted, where, and by whom, even when teams only know a timeframe or channel name. Investigations that once took weeks — or weren’t possible at all — can now be completed in hours. By eliminating manual effort and surfacing hidden risks across sprawling data estates, Data Security Investigations empowers teams to investigate more efficiently and confidently, making deep, scalable investigations a reality. What Microsoft Purview Data Security Investigations does – and what’s new Since launching public preview, we've listened closely to customer feedback and made significant enhancements to help teams investigate faster, mitigate more effectively, and manage costs with confidence. Data Security Investigations addresses three critical stages of an investigation: Identify impacted data Data Security admins can efficiently identify relevant data by searching their Microsoft 365 data estate to locate emails, Teams messages, Copilot prompts and responses, and documents. Investigators can also launch pre-scoped investigations from a Microsoft Defender XDR incident or a Microsoft Purview Insider Risk Management case. We’ve recently added a new integration that allows admins to launch a Data Security Investigation from Microsoft Purview Data Security Posture Management as well. This capability can help a data security admin investigate an objective, such as preventing data exfiltration. Investigate using deep content analysis Once the investigation is scoped, the solution's generative AI capabilities allow admins to gain deeper insights into the data, analyzing across 95+ languages to uncover critical sensitive data and security risks. Teams can quickly answer three questions: What data security risks exist within the data? Why do they matter? And what actions can be taken to mitigate them? To help answer these questions, two new investigative capabilities, AI search and AI context input, as well as enhancements to existing features were added in November. Data Security Investigations help admins scale their impact and accelerate investigations with the following features: AI search: Using a new AI-powered natural language search experience, admins can find key risks using keywords, metadata, and semantic embeddings — making it easier to locate investigation-relevant content across large data estates. Categorization: By automatically classifying investigation data into meaningful categories, admins can quickly understand incident severity, what types of content is at risk, and trends within an investigation. Vector search: Using semantic search, admins can find contextually related content — even when exact keywords don't match. Risk examination: Using deep content analysis, admins can examine content for sensitive data and security risks, providing a risk score, recommended mitigation steps, and AI-generated rationale for each analyzed asset. AI context input: Admins can now add investigation-specific context before analysis, resulting in more efficient, higher-quality insights tailored to the specific incident. AI search in action, finding credentials present in the dataset being investigated. Mitigate identified risks Investigators can use Data Security Investigations to securely collaborate with partner teams to mitigate identified risks, simplifying tasks that have traditionally been time consuming and complex. In September, we launched an integration with the Microsoft Sentinel graph, the data risk graph, allowing admins to visualize correlations between investigation data, users, and their activities. This automatically combines unified audit logs, Entra audit logs, and threat intelligence, which would otherwise need to be manually correlated, saving time, providing critical context, and allowing investigators to understand all nodes in their investigation. At the start of January 2026, we launched a new mitigation action, purge, that helps admins quickly and efficiently delete sensitive or overshared content directly within the investigation workflow in the product interface. This reduces exposure immediately and keeps incidents from escalating or recurring. Built-in cost management tools To help customers predict and manage costs associated with using Data Security Investigations, we recently released a lightweight cost estimator and usage dashboard. The in-product cost estimator is now available to help analysts model and forecast both storage and compute unit costs based on specific use cases, enabling more accurate budget planning. Additionally, the usage dashboard provides granular breakdowns of billed storage and compute unit usage, empowering data security admins to identify cost-saving opportunities and optimize resource allocation. For detailed guidance on managing costs, see https://aka.ms/DSIcostmanagementtips. Refined business model for general availability These cost management tools are designed to support our updated business model, which offers greater flexibility and transparency. Customers need the freedom to scale investigations without overcommitting resources. To better align with how customers investigate data risk at scale, we refined the Data Security Investigations business model as part of general availability. The product now uses two consumptive meters: Data Security Investigations Storage Meter – For storing investigation-related data, charged by GB Data Security Investigations Compute Meter – For the computational capacity required to complete AI-powered data analysis and actions, charged by Compute Units (CUs) Monthly charges are determined by the amount of data stored and the number of CUs consumed per hour. This pay-as-you-go model ensures customers only pay for what they need when they need it, providing the flexibility, scalability, and cost efficiency needed for both urgent incident response and proactive data security hygiene assessments.

The CAF 4.0 update reframes C2 (Threat Hunting) as a cornerstone of proactive cyber resilience. According to the NCSC CAF 4.0, this principle is no longer about occasional investigations or manual log reviews; it now demands structured, frequent, and intelligence-led threat hunting that evolves in line with organizational risk. The expectation is that UK public sector organizations will not just respond to alerts but will actively search for hidden or emerging threats that evade standard detection technologies, documenting their findings and using them to strengthen controls and response. In practice, this represents a shift from detection to anticipation. Threat hunting under CAF 4.0 should be hypothesis-driven, focusing on attacker tactics, techniques, and procedures (TTPs) rather than isolated indicators of compromise (IoCs). Organizations must build confidence that their hunting processes are repeatable, measurable, and continuously improving, leveraging automation and threat intelligence to expand coverage and consistency. Microsoft E3 Microsoft E3 equips organizations with the baseline capabilities to begin threat investigation, forming the starting point for Partially Achieved maturity under CAF 4.0 C2. At this level, hunting is ad hoc and event-driven, but it establishes the foundation for structured processes. How E3 contributes to the following objectives in C2: Reactive detection for initial hunts: Defender for Endpoint Plan 1 surfaces alerts on phishing, malware, and suspicious endpoint activity. Analysts can use these alerts to triage incidents and document steps taken, creating the first iteration of a hunting methodology. Identity correlation and manual investigation: Entra ID P1 provides Conditional Access and MFA enforcement, while audit telemetry in the Security & Compliance Centre supports manual reviews of identity anomalies. These capabilities allow organizations to link endpoint and identity signals during investigations. Learning from incidents: By recording findings from reactive hunts and feeding lessons into risk decisions, organizations begin to build repeatable processes, even if hunts are not yet hypothesis-driven or frequent enough to match risk. What’s missing for Achieved: Under E3, hunts remain reactive, lack documented hypotheses, and do not routinely convert findings into automated detections. Achieving full maturity typically requires regular, TTP-focused hunts, automation, and integration with advanced analytics, capabilities found in higher-tier solutions. Microsoft E5 Microsoft E5 elevates threat hunting from reactive investigation to a structured, intelligence-driven discipline, a defining feature of Achieved maturity under CAF 4.0, C2. Distinctive E5 capabilities for C2: Hypothesis-driven hunts at scale: Defender Advanced Hunting (KQL) enables analysts to test hypotheses across correlated telemetry from endpoints, identities, email, and SaaS applications. This supports hunts focused on adversary TTPs, not just atomic IoCs, as CAF requires. Turning hunts into detections: Custom hunting queries can be converted into alert rules, operationalizing findings into automated detection and reducing reliance on manual triage. Threat intelligence integration: Microsoft Threat Intelligence feeds real-time actor tradecraft and sector-specific campaigns into the hunting workflow, ensuring hunts anticipate emerging threats rather than react to incidents. Identity and lateral movement focus: Defender for Identity surfaces Kerberos abuse, credential replay, and lateral movement patterns, enabling hunts that span beyond endpoints and email. Documented and repeatable process: E5 supports recording hunt queries and outcomes via APIs and portals, creating evidence for audits and driving continuous improvement, a CAF expectation. By embedding hypothesis-driven hunts, automation, and intelligence into business-as-usual operations, E5 helps public sector organizations meet CAF C2’s requirement for regular, documented hunts that proactively reduce risk, and evolve with the threat landscape. Sentinel Microsoft Sentinel takes threat hunting beyond the Microsoft ecosystem, unifying telemetry from endpoints, firewalls, OT systems, and third-party SaaS into a single cloud-native SIEM and SOAR platform. This consolidation helps enable hunts that span the entire attack surface, a critical step toward achieving maturity under CAF 4.0 C2. Key capabilities for control C2: Attacker-centric analysis: MITRE ATT&CK-aligned analytics and KQL-based hunting allow teams to identify stealthy behaviours, simulate breach paths, and validate detection coverage. Threat intelligence integration: Sentinel enriches hunts with national and sector-specific intelligence (e.g. NCSC advisories), ensuring hunts target the most relevant TTPs. Automation and repeatability: SOAR playbooks convert post-hunt findings into automated workflows for containment, investigation, and documentation, meeting CAF’s requirement for structured, continuously improving hunts. Evidence-driven improvement: Recorded hunts and automated reporting create a feedback loop that strengthens posture and demonstrates compliance. By combining telemetry, intelligence, and automation, Sentinel helps organizations embed threat hunting as a routine, scalable process, turning insights into detections and ensuring hunts evolve with the threat landscape. The video below shows how E3, E5 and Sentinel power real C2 threat hunts. Bringing it all Together By progressing from E3’s reactive investigation to E5’s intelligence-led correlation and Sentinel’s automated hunting and orchestration, organizations can develop an end-to-end capability that not only detects but anticipates and helps prevent disruption to essential public services across the UK. This is the operational reality of Achieved under CAF 4.0 C2 (Threat Hunting) - a structured, data-driven, and intelligence-informed approach that transforms threat hunting from an isolated task into an ongoing discipline of proactive defence. To demonstrate what effective, CAF-aligned threat hunting looks like, the following one-slider and demo walk through how Microsoft’s security tools support structured, repeatable hunts that match organizational risk. These examples help translate C2’s expectations into practical, operational activity. CAF 4.0 challenges public-sector defenders to move beyond detection and embrace anticipation. How mature is your organization’s ability to uncover the threats that have not yet been seen? In this final post of the series, the message is clear - true cyber resilience moves beyond reactivity towards a predictive approach.Security Guidance Series: CAF 4.0 Understanding Threat From Awareness to Intelligence-Led Defence
The updated CAF 4.0 raises expectations around control A2.b - Understanding Threat. Rather than focusing solely on awareness of common cyber-attacks, the framework now calls for a sector-specific, intelligence-informed understanding of the threat landscape. According to the NCSC, CAF 4.0 emphasizes the need for detailed threat analysis that reflects the tactics, techniques, and resources of capable adversaries, and requires that this understanding directly shapes security and resilience decisions. For public sector authorities, this means going beyond static risk registers to build a living threat model that evolves alongside digital transformation and service delivery. Public sector authorities need to know which systems and datasets are most exposed, from citizen records and clinical information to education systems, operational platforms, and payment gateways, and anticipate how an attacker might exploit them to disrupt essential services. To support this higher level of maturity, Microsoft’s security ecosystem helps public sector authorities turn threat intelligence into actionable understanding, directly aligning with CAF 4.0’s Achieved criteria for control A2.b. Microsoft E3 - Building Foundational Awareness Microsoft E3 provides public sector authorities with the foundational capabilities to start aligning with CAF 4.0 A2.b by enabling awareness of common threats and applying that awareness to risk decisions. At this maturity level, organizations typically reach Partially Achieved, where threat understanding is informed by incidents rather than proactive analysis. How E3 contributes to Contributing Outcome A2.b: Visibility of basic threats: Defender for Endpoint Plan 1 surfaces malware and unsafe application activity, giving organizations insight into how adversaries exploit endpoints. This telemetry helps identify initial attacker entry points and informs reactive containment measures. Identity risk reduction: Entra ID P1 enforces MFA and blocks legacy authentication, mitigating common credential-based attacks. These controls reduce the likelihood of compromise at early stages of an attacker’s path. Incident-driven learning: Alerts and Security & Compliance Centre reports allow organizations to review how attacks unfolded, supporting documentation of observed techniques and feeding lessons into risk decisions. What’s missing for Achieved: To fully meet the contributing outcomes A2.b, public sector organizations must evolve from incident-driven awareness to structured, intelligence-led threat analysis. This involves anticipating probable attack methods, developing plausible scenarios, and maintaining a current threat picture through proactive hunting and threat intelligence. These capabilities extend beyond the E3 baseline and require advanced analytics and dedicated platforms. Microsoft E5 – Advancing to Intelligence-Led Defence Where E3 establishes the foundation for identifying and documenting known threats, Microsoft E5 helps public sector organizations to progress toward the Achieved level of CAF control A2.b by delivering continuous, intelligence-driven analysis across every attack surface. How E5 aligns with Contributing Outcome A2.b: Detailed, up-to-date view of attacker paths: At the core of E5 is Defender XDR, which correlates telemetry from Defender for Endpoint Plan 2, Defender for Office 365 Plan 2, Defender for Identity, and Defender for Cloud Apps. This unified view reveals how attackers move laterally between devices, identities, and SaaS applications - directly supporting CAF’s requirement to understand probable attack methods and the steps needed to reach critical targets. Advanced hunting and scenario development: Defender for Endpoint P2 introduces advanced hunting via Kusto Query Language (KQL) and behavioural analytics. Analysts can query historical data to uncover persistence mechanisms or privilege escalation techniques, assisting organizations to anticipate attack chains and develop plausible scenarios, a key expectation under A2.b. Email and collaboration threat modelling: Defender for Office 365 P2 detects targeted phishing, business email compromise, and credential harvesting campaigns. Attack Simulation Training adds proactive testing of social engineering techniques, helping organizations maintain awareness of evolving attacker tradecraft and refine mitigations. Identity-focused threat analysis: Defender for Identity and Entra ID P2 expose lateral movement, credential abuse, and risky sign-ins. By mapping tactics and techniques against frameworks like MITRE ATT&CK, organizations can gain the attacker’s perspective on identity systems - fulfilling CAF’s call to view networks from a threat actor’s lens. Cloud application risk visibility: Defender for Cloud Apps highlights shadow IT and potential data exfiltration routes, helping organizations to document and justify controls at each step of the attack chain. Continuous threat intelligence: Microsoft Threat Intelligence enriches detections with global and sector-specific insights on active adversary groups, emerging malware, and infrastructure trends. This sustained feed helps organizations maintain a detailed understanding of current threats, informing risk decisions and prioritization. Why this meets Achieved: E5 capabilities help organizations move beyond reactive alerting to a structured, intelligence-led approach. Threat knowledge is continuously updated, scenarios are documented, and controls are justified at each stage of the attacker path, supporting CAF control A2.b’s expectation that threat understanding informs risk management and defensive prioritization. Sentinel While Microsoft E5 delivers deep visibility across endpoints, identities, and applications, Microsoft Sentinel acts as the unifying layer that helps transform these insights into a comprehensive, evidence-based threat model, a core expectation of Achieved maturity under CAF 4.0 A2.b. How Sentinel enables Achieved outcomes: Comprehensive attack-chain visibility: As a cloud-native SIEM and SOAR, Sentinel ingests telemetry from Microsoft and non-Microsoft sources, including firewalls, OT environments, legacy servers, and third-party SaaS platforms. By correlating these diverse signals into a single analytical view, Sentinel allows defenders to visualize the entire attack chain, from initial reconnaissance through lateral movement and data exfiltration. This directly supports CAF’s requirement to understand how capable, well-resourced actors could systematically target essential systems. Attacker-centric analysis and scenario building: Sentinel’s Analytics Rules and MITRE ATT&CK-aligned detections provide a structured lens on tactics and techniques. Security teams can use Kusto Query Language (KQL) and advanced hunting to identify anomalies, map adversary behaviours, and build plausible threat scenarios, addressing CAF’s expectation to anticipate probable attack methods and justify mitigations at each step. Threat intelligence integration: Sentinel enriches local telemetry with intelligence from trusted sources such as the NCSC and Microsoft’s global network. This helps organizations maintain a current, sector-specific understanding of threats, applying that knowledge to prioritize risk treatment and policy decisions, a defining characteristic of Achieved maturity. Automation and repeatable processes: Sentinel’s SOAR capabilities operationalize intelligence through automated playbooks that contain threats, isolate compromised assets, and trigger investigation workflows. These workflows create a documented, repeatable process for threat analysis and response, reinforcing CAF’s emphasis on continuous learning and refinement. This video brings CAF A2.b – Understanding Threat – to life, showing how public sector organizations can use Microsoft security tools to build a clear, intelligence-led view of attacker behaviour and meet the expectations of CAF 4.0. Why this meets Achieved: By consolidating telemetry, threat intelligence, and automated response into one platform, Sentinel elevates public sector organizations from isolated detection to an integrated, intelligence-led defence posture. Every alert, query, and playbook contributes to an evolving organization-wide threat model, supporting CAF A2.b’s requirement for detailed, proactive, and documented threat understanding. CAF 4.0 challenges every public-sector organization to think like a threat actor, to understand not just what could go wrong, but how and why. Does your organization have the visibility, intelligence, and confidence to turn that understanding into proactive defence? To illustrate how this contributing outcome can be achieved in practice, the one-slider and demo show how Microsoft’s security capabilities help organizations build the detailed, intelligence-informed threat picture expected by CAF 4.0. These examples turn A2.b’s requirements into actionable steps for organizations. In the next article, we’ll explore C2 - Threat Hunting: moving from detection to anticipation and embedding proactive resilience as a daily capability.Microsoft Ignite 2025: Top Security Innovations You Need to Know

It’s Time To Act Microsoft's Digital Defense Report 2025 clearly describes the cyber threat landscape that this guidance is situated in, one that has become more complex, more industrialized, and increasingly democratized. Each day, Microsoft processes more than 100 trillion security signals, giving unparalleled visibility into adversarial tradecraft. Identity remains the most heavily targeted attack vector, with 97% of identity-based attacks relying on password spray, while phishing and unpatched assets continue to provide easy routes for initial compromise. Financially motivated attacks, particularly ransomware and extortion, now make up over half of global incidents, and nation-state operators continue to target critical sectors, including IT, telecommunications, and Government networks. AI is accelerating both sides of the equation: enhancing attacker capability, lowering barriers to entry through open-source models, and simultaneously powering more automated, intelligence-driven defence. Alongside this, emerging risks such as quantum computing underline the urgency of preparing today for tomorrow’s threats. Cybersecurity has therefore become a strategic imperative shaping national resilience and demanding genuine cross-sector collaboration to mitigate systemic risk. It is within this environment that UK public sector organizations are rethinking their approach to cyber resilience. As an Account Executive Apprentice in the Local Public Services team here at Microsoft, I have seen how UK public sector organizations are rethinking their approach to cyber resilience, moving beyond checklists and compliance toward a culture of continuous improvement and intelligence-led defence. When we talk about the UK public sector in this series, we are referring specifically to central government departments, local government authorities, health and care organizations (including the NHS), education institutions, and public safety services such as police, fire, and ambulance. These organizations form a deeply interconnected ecosystem delivering essential services to millions of citizens every day, making cyber resilience not just a technical requirement but a foundation of public trust. Against this backdrop, the UK public sector is entering a new era of cyber resilience with the release of CAF 4.0, the latest evolution of the National Cyber Security Centre’s Cyber Assessment Framework. This guidance has been developed in consultation with national cyber security experts, including the UK’s National Cyber Security Centre (NCSC), and is an aggregation of knowledge and internationally recognized expertise. Building on the foundations of CAF 3.2, this update marks a decisive shift, like moving from a static map to a live radar. Instead of looking back at where threats once were, organizations can now better anticipate them and adjust their digital defences in real time. For the UK’s public sector, this transformation could not be timelier. The complexity of digital public services, combined with the growing threat of ransomware, insider threat, supply chain compromise, and threats from nation state actors, demands a faster, smarter, and more connected approach to resilience. Where CAF 3.2 focused on confirming the presence and effectiveness of security measures, CAF 4.0 places greater emphasis on developing organizational capability and improving resilience in a more dynamic threat environment. While the CAF remains an outcome-based framework, not a maturity model, it is structured around Objectives, Principles, and Contributing Outcomes, with each contributing outcome supported by Indicators of Good Practice. For simplicity, I refer to these contributing outcomes as “controls” throughout this blog and use that term to describe the practical expectations organizations are assessed against. CAF 4.0 challenges organizations not only to understand the threats they face but to anticipate, detect, and respond in a more informed and adaptive way. Two contributing outcomes exemplify this proactive mindset: A2.b Understanding Threat and C2 Threat Hunting. Together, they represent what it truly means to understand your adversaries and act before harm occurs. For the UK’s public sector, achieving these new objectives may seem daunting, but the path forward is clearer than ever. Many organizations are already beginning this journey, supported by technologies that help turn insight into action and coordination into resilience. At Microsoft, we’ve seen how tools like E3, E5, and Sentinel are already helping public sector teams to move from reactive to intelligence-driven security operations. Over the coming weeks, we’ll explore how these capabilities align to CAF 4.0’s core principles and share practical examples of how councils can strengthen their resilience journey through smarter visibility, automation, and collaboration. CAF 4.0 vs CAF 3.2 - What’s Changed and Why It Matters The move from CAF 3.2 to CAF 4.0 represents a fundamental shift in how the UK public sector builds cyber resilience. The focus is no longer on whether controls exist - it is on whether they work, adapt, and improve over time. CAF 4.0 puts maturity at the centre. It pushes organizations to evolve from compliance checklists to operational capability, adopting a threat-informed, intelligence-led, and proactive security posture, by design. CAF 4.0 raises the bar for cyber maturity across the public sector. It calls for departments and authorities to build on existing foundations and embrace live threat intelligence, behavioural analytics, and structured threat hunting to stay ahead of adversaries. By understanding how attackers might target essential services and adapting controls in real time, organizations can evolve from awareness to active defence. Today’s threat actors are agile, persistent, and increasingly well-resourced, which means reactive measures are no longer enough. CAF 4.0 positions resilience as a continuous process of learning, adapting, and improving, supported by data-driven insights and modern security operations. CAF 4.0 is reshaping how the UK’s public sector approaches security maturity. In the coming weeks, we’ll explore what this looks like in practice, starting with how to build a deeper understanding of threat (control A2.b) and elevate threat hunting (control C2) into an everyday capability, using the tools and insights that are available within existing Microsoft E3 and E5 licences to help support these objectives. Until then, how ready is your organization to turn insight into action?

Learn how to get startedUncover hidden security risks with Microsoft Sentinel graph
Earlier this fall, we launched Microsoft Sentinel graph – and today, we are pleased to announce that Sentinel graph is generally available starting December 1, 2025. Microsoft Sentinel graph maps the interconnections across activity, asset, and threat intelligence data. This enables comprehensive graph-based security and analysis across pre-and post-breach scenarios in both Microsoft Defender and Microsoft Purview. Customers are already seeing the impact of the graph-powered experiences that is providing insights beyond tabular queries. "The predefined scenarios in Sentinel graph are excellent... it definitely shows where I would need to look as an investigator to figure out what's happening in my environment, who has access to it, not only directly, but also indirectly, a couple of hops away. And that's something that you really can't get through a standard KQL query..." - Gary Bushey, Security Architect, Cyclotron, Inc. Building on this foundation, we are taking Sentinel graph to the next level and are excited to announce the public preview of the following new capabilities. Graph MCP Tools Building on the hunting graph and blast radius analysis capabilities in Microsoft Defender portal. We are excited to announce preview of purpose-built Sentinel graph MCP tools (Blast Radius, Path Discovery, and Exposure Perimeter) that make the graph-powered insights accessible to the AI agents. Using these purpose-built Sentinel graph MCP tools, you will be able to use and build AI agents to get insights from the graph in natural language (figure 1): “What is the blast radius from ‘Laura Hanak’?” “Is there a path from user Mark Gafarov to key vault wg-prod?” “Who can all get to wg-prod key vault?” You can sign up here for a free preview of Sentinel graph MCP tools, which will also roll out starting December 1, 2025. Custom Graphs The security operations teams, including Tier-3 analysts, threat intelligence specialists, and security researchers play a critical role in investigating sophisticated attacks and addressing systemic security issues. Their responsibilities range from uncovering design vulnerabilities and tracing historical exploitation, to analyzing types of abuse and recommending effective solutions. These experts strive to identify hidden patterns within organizational data and struggle with the right tools that can help them differentiate between normal vs. abnormal, keep-up with the changing attack patterns, and handle massive and complex datasets at scale. This requires a high level of flexibility and customization to rapidly iterate on the analysis. We’re taking Microsoft Sentinel graph to the next level and are thrilled to announce the public preview of custom graphs with two new powerful approaches designed specifically for security: ephemeral custom graphs and materialized custom graphs. These innovative approaches empower defenders to create and analyze graphs tailored and tuned to their unique security scenarios to find hidden risks and patterns in their security data available in the Sentinel data lake. Using their data in the lake, defenders will be able author notebooks (figure 2) to model, build, visualize, traverse, and run advanced graph analyses like Chokepoint/Centrality, Blast Radius/Reachability, Prioritized Path/Ranked, and K-hop. It’s a transformative leap in graph analytics, fundamentally changing how security teams understand and mitigate organizational risk by connecting the dots in their data. Figure 2: Custom graphs using Notebook in VS Code You can sign up here for a free preview of custom graph capability, which will also roll out starting December 1, 2025. Ephemeral Custom Graphs Ephemeral custom graphs are for one-time investigations requiring quick pattern examination and rapidly changing large scale data that doesn't justify materialization for reuse. For example, in a typical SOC investigation, brute-force attempts or privilege escalations appear as isolated incidents. But in reality, attackers move laterally through interconnected credentials and resources. Let’s assume, a service account (svc-backup) used by a legacy database is compromised. It holds group membership in “DataOps-Admins,” which shares access with “Engineering-All.” A developer reuses their personal access token across staging and production clusters. Individually, these facts seem harmless. Together, they form a multi-hop credential exposure chain that can only be detected through graph traversal. Sentinel graph helps you to build ad-hoc graphs for an investigation and discarded afterward (not kept in a database for reuse). You can pull the data from the Sentinel data lake and build a graph to explore relationships, run analytics, iterate on nodes/edges, and refine queries in an interactive loop. Here are some additional scenarios where ephemeral custom graphs can expose hidden patterns: Sign-in anomaly hunting: An analyst graphs user logins against source IPs and timestamps to identify unusual patterns (like a single IP connecting to many accounts). By iterating on the graph (filtering nodes, adding context like geolocation), they can spot suspicious login clusters or a credential theft scenario. TTP (Tactics, Techniques, Procedures) investigation: For a specific threat (e.g., a known APT’s techniques), the hunter might use a graph template to map related events. Microsoft Sentinel, for instance, can provide hunting notebook templates for scenarios like investigating lateral movement or scanning logs for leaked credentials, so analysts quickly construct a graph of relevant evidence. Audit log pattern discovery: By graphing Office 365 activity logs or admin audit logs, defenders can apply advanced graph algorithms (like betweenness centrality) to find outliers – e.g., an account that intermediates many rare files access relationships might indicate insider abuse. Materialized Custom Graphs Materialized custom graphs are graph datasets that are stored and maintained over time, often updated at intervals (e.g., daily or hourly). Instead of being thrown away each session, these graphs will be materialized in the graph database for running graph analytics and visualization. Materialized custom graphs will enable organizations to create their custom enterprise knowledge graphs for various use cases, such as every organization already has an identity graph — they just haven’t visualized it yet. Imagine a large enterprise where users, devices, service principals, and applications are constantly changing. New credentials are issued, groups evolve, and permissions shift by the hour. Over time, this churn creates a complex web of implicit trust and shared access that no static tool can capture. Organizations can now build their own identity graphs and materialize them. These materialized custom graphs can continuously map relationships across Azure AD Domain Services, Entra ID, AWS IAM, SaaS platforms, and custom applications, updating daily or hourly to reflect the organization’s true security topology. Organizations can query these graphs and run various advanced graph algorithms and understand the chokepoint, blast radius, attack paths, and so on. This helps detect the gradual buildup of privilege overlap — when identities that were once isolated begin to share access paths through evolving group memberships, role assignments, or inherited permissions. Over weeks or months, these subtle shifts expand the blast radius of any single compromise. Behind the scenes We are partnering with our friends in Microsoft Fabric to bring these new capabilities to market. Mapping a large digital estate into a graph requires new scale out approach and that is what graph in Microsoft Fabric enables. “Discovering modern security risks is a massive data challenge. It requires connecting the dots across an entire digital estate, which can only be achieved with a graph at hyperscale. This is why our Fabric team's partnership with the Sentinel graph team is so critical. We’ve collaborated to build a scale-out graph solution capable of processing billion nodes and edges, delivering the performance and scale our largest security customers need to stay ahead of threats.” - Yitzhak Kesselman, CVP, Fabric Real-Time Intelligence Getting started Check out this video to learn more.

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. Identity admins can discover and activate partner offerings for DDoS protection, intelligent bot defense, and government ID–based verification for account recovery —all within the Entra portal. With these capabilities, Microsoft Entra delivers a seamless, multi-layered defense that combines built-in identity protection with best-in-class partner technologies, making it easier than ever for enterprises to strengthen resilience against modern identity threats.

Start Secure and Stay Secure on your AI Agent Journey with Microsoft Defender
Introduction The power of AI agents is their autonomy – their ability to understand context, dynamically adjust workflows, orchestrate tooling, and act with little to no human interaction. But that same autonomous decision-making amplifies security risks. Not only are we seeing a geometric rise in the volume of agents being added to our workforce, but the attack techniques and surface area these agents introduce are fundamentally different than anything before. Analysts expect more than 1.3 billion agents will be in operation by 2028. To put that into perspective, if they were their own country today, they would rank 3rd in population, behind only India and China. The proliferation of pro-code, low-code, and no-code agent-building platforms is further democratizing agent creation and will continue to drive the massive growth we expect in the coming years. These new waves of AI tinkerers, many without extensive developer-level security knowledge, have the potential to introduce additional risks without even realizing it. Today, we are excited to announce new capabilities in Microsoft Defender that help security administrators and security analysts manage agent risks and threats, as part of Microsoft Agent 365. Security teams will now benefit from a unified approach to manage posture and protect against threats across the AI agent lifecycle. Introducing AI Agent security within Microsoft Defender At Ignite 2025, Microsoft Defender is announcing the preview of unified posture management and threat protection for AI agents. These new agent security capabilities will be added to existing product experiences, as well as Microsoft Agent 365. This evolution broadens Defender’s AI security capabilities to cover agentic AI services on pro-code platforms like Microsoft Foundry and low-code/no-code environments such as Copilot Studio. AI security posture management for Microsoft Foundry agents, as well as threat protection for Copilot Studio agents, are now in preview. Threat protection for Microsoft Foundry agents will be available soon. Core Capabilities 1. Comprehensive Visibility for AI Agents Gain a unified, risk-based inventory of AI agents across Microsoft Foundry and Copilot Studio to eliminate blind spots and reduce shadow agents. Defender consolidates metadata, instructions, identities, and connected tools—helping security administrators manage sprawl and maintain control. Unlike point solutions, Defender’s posture, alerts, and response capabilities cover the entire AI stack within a unified portal and experience. AI agent inventory in Defender 2. Risk Reduction for AI Agents Defender strengthens posture by identifying misconfigurations, excessive permissions, and insecure instructions. AI security posture recommendations and detailed attack path analysis contextualize how weak spots from Microsoft Foundry agents form broader risks for the organization, enabling proactive remediation before breaches occur. Pre-built advanced hunting queries help security teams spot potential vulnerabilities within Copilot Studio agents. 2: Attack path analysis for AI agents 3. Threat Protection for AI Agents The rise of AI agents introduces entirely new threats that traditional security tools aren’t equipped to handle, including prompt injection and privilege compromise. Attackers can exploit an agent’s language understanding with manipulative inputs that evade classic defenses, demanding fresh approaches to security. Defender is expanding its threat protections for generative AI to include new protection for AI agent-specific threats. New jailbreak attempt alerts and real-time blocking of unsafe tool invocation for Copilot Studio agents are automatically correlated with broader threat signals and insights from the industry-leading Microsoft Threat Intelligence, to deliver contextual alerts and incident-level visibility. Similar detections for Microsoft Foundry agents will also be available in preview soon. 3: Threat protection for AI agents Above-mentioned threat signals are further contextualized within Microsoft Defender and Sentinel, seamlessly connecting Microsoft’s security, AI, and DevOps platforms like Microsoft Defender, Foundry, Copilot Studio, and GitHub Advanced Security, helping organizations start secure and shift AI security farther left. Additionally, Defender is expanding the threat hunting experience to include logs for Copilot Studio, Azure Foundry, and agents built on third-party agent builder platforms through the A365 SDK. This enhancement will provide security teams with even more insight into agentic threats and incident context. Customer Scenarios With these capabilities, customers can protect AI agents better with these specific use cases: Gain visibility and insight: Eliminate shadow agents and unify AI asset management across multi-cloud platforms. • Conduct risk reduction: Understand vulnerabilities with posture recommendations and prioritize proactive hardening with attack-path analysis. • Threat protection: Monitor runtime activity for malicious patterns, block prompt injection attacks, and correlate signals for incident context. What Sets Defender Apart AI agents are just one of many potential threat vectors within your organization that attackers may target. Unlike point solutions, Defender offers build-to-runtime protection across the AI stack—models, agents, SaaS apps, and cloud infrastructure. The power of this unified approach is that it extends beyond AI. Correlating security posture, attack paths, and alerts across endpoints, identities, applications, cloud infrastructure, and other signals helps security practitioners better understand threats and coordinate response within a single experience, reducing complexity and enabling continuous security. Looking Ahead Microsoft remains committed to helping customers start secure and stay secure on their AI journey.
