How Karambit.AI and Microsoft Bring Software Authenticity to 14 Billion Files Per Month
The Problem: Static Analysis Without Context Traditional static analysis treats every file as an island. Scan a binary, match against known signatures, flag what you recognize. The approach is well-understood and increasingly insufficient against modern threats. The fundamental limitation is the absence of context. Without it, a packer is just a packer. A network call is just a network call. An obfuscation routine is just an obfuscation routine. Whether that behavior is normal or anomalous, whether it belongs in this software, in this ecosystem, performing this function, is invisible to tools that evaluate files in isolation. Attackers exploit this gap. They hide malicious behavior inside legitimate software patterns, evolve their techniques between versions, and distribute intent across multiple components so that no single artifact triggers a detection in a context-free scan. Context-Aware Behavior Analysis Context-aware analysis inverts the model. Instead of asking "is this file bad?" it asks: "is this file behaving the way it should, given everything we know about this ecosystem?" This requires building and maintaining behavioral context across multiple dimensions: Ecosystem-level behavioral baselines: Understanding what behaviors are normal across the entire corpus and which should never appear. In a trusted software ecosystem, obfuscated or packed content is itself an anomaly worth enforcing policy against, regardless of whether the underlying payload is known-malicious. Behavioral chains with low false-positive rates: Individual API calls and instructions are ambiguous in isolation. Context-aware analysis identifies chains of behaviors, sequences where data staging feeds into exfiltration, or where privilege escalation is followed by persistence mechanisms, that reveal intent with high confidence. Cross-file and cross-instance correlation: Behaviors observed in one file are evaluated against patterns seen across millions of other files and scan instances. Shared behavioral fingerprints reveal family relationships, evolutionary lineage, and coordinated campaigns that single-file analysis cannot surface. Historical behavioral deltas: What changed between version N and version N+1? New behaviors in an update, especially behaviors that don't correspond to documented changes, are flagged not because they match a signature, but because they deviate from the established behavioral profile. The result: dramatically higher detection confidence, lower false-positive rates, and the ability to enforce behavioral policy at the ecosystem level. Case Study: Packer_Dictator, Behavioral Detection Under Adversary Adaptation Adversaries must change their Tactics, Techniques, and Procedures (TTPs) over time. When a detection capability catches them, they adapt to evade it. This is expected behavior and it is precisely why general detections at the behavior level are more durable than signature-based approaches. Behavioral patterns are fundamentally harder for adversaries to change without breaking their own tooling. The packer family tracked as packer_dictator illustrates this dynamic clearly. Initial Detection: Obvious Indicators Early variants of packer_dictator used conspicuous binary section names: authoritarian and politically-themed strings that made identification straightforward for anyone examining the PE headers. These were low-hanging indicators, but Karambit.AI's detection wasn't built on them. The system flagged these samples based on their behavioral profile: the entropy characteristics of their packed sections, the structure of their unpacker initialization routines, and the other patterns used to unpack and execute hidden payloads. Adversary Adaptation: Surface Changes, Persistent Behavior As detections rolled out, the users of this packer had to adapted. The obvious section names disappeared, replaced by more benign alternatives: .upx0, standard "unpacked" section names, and other strings designed to blend in with legitimate software. But the underlying behavior didn't change because it couldn't, not without fundamentally rearchitecting the packer itself. Entropy Analysis: Seeing Through Surface Changes Sliding-window entropy analysis reveals why surface-level changes are insufficient to evade behavioral detection. The entropy profiles of packer_dictator samples, even after the section name changes, maintain a characteristic signature: Both profiles exhibit the same structural pattern: a low-entropy region corresponding to the unpacker stub, followed by a sharp transition to a high-entropy plateau spanning the packed payload. This entropy profile is indicative of hidden behaviors, content that has been deliberately obscured, though not necessarily malicious content on its own. The profile shape, transition points, and entropy floor/ceiling ratios form a behavioral fingerprint that persists across variants regardless of metadata changes. Unpacker Initialization: Common Structure Enables Generalized Detection At the disassembly level, packer_dictator variants share a common unpacker initialization sequence that enables generalized analysis across the family. Examining the entry-point code of two samples reveals the structural similarity: Both samples exhibit a characteristic pattern: Register preservation: PUSH R9/PUSH R11 followed by PUSHFQ to save register state and flags before the unpack routine modifies them. Immediate constant loading: Large immediate values loaded into registers (MOV R9, 0x689f8c87eebd998c / MOV R11, 0x6592b8afc22b0736) that serve as decryption keys or XOR masks for the unpacking routine. Arithmetic flag manipulation: Sequences of TEST, NEG, OR, CMP, NOT, and SETNS instructions that compute control flow decisions based on the loaded constants — a form of opaque predicate that obscures the true branch target. Stack-based payload resolution: MOV instructions referencing [RSP + local_120] / [RSP + 0x8] with additional immediate constants written to the stack, setting up parameters for the decompression/decryption loop. The structural template is consistent even as the specific constants, register assignments, and opaque predicate formulations change between variants. This is what makes behavioral detection durable: the adversary can rotate constants and rename sections, but the computational structure required to unpack the payload is constrained by the packer's architecture. By generalizing detection to this structural level, Karambit.AI's engine identifies new packer_dictator variants, and structurally related packer families, without requiring signature updates for each iteration. And this is only one example of the resilience of Karambit.AI’s resilience in the face of constantly advancing adversaries. From Karambyte to Karambiner: Engineering for Billions Karambyte: Building the Context Karambyte was Karambit.AI's original analysis engine, purpose-built for deep behavioral extraction from compiled binaries. Its core function was to extract behavioral context, disassemble control flow, API call chains, entropy profiles, packer identification, behavioral intent classification, and store it for comparison and reference. Karambyte proved the model. It demonstrated that context-aware behavioral analysis could identify threats that traditional static analysis missed, by building rich behavioral profiles and comparing them across software versions and file populations. The system extracted context and maintained it internally, enabling the cross-file and cross-version correlation that drove detections like packer_dictator. But Karambyte's architecture, extracting and storing context within the same system, created a scaling constraint. As adoption grew and the target moved from hundreds of thousands to billions of files per month, the tight coupling between analysis and context storage became the bottleneck. Karambiner: Externalizing Context for Scale Karambiner re-architected the relationship between analysis and context. Rather than each analysis instance maintaining its own behavioral context store, Karambiner externalized the context layer into a dedicated reference that can then be customized for the specific organizational context. This separation enabled three critical capabilities at scale: Horizontal analysis throughput: Analysis scales independently of the context store. Adding processing capacity doesn't require replicating the full behavioral knowledge base. Context enrichment: Behavioral context extracted from collective scans can be used in the massively scalable analysis engine. Ecosystem-wide policy enforcement: With externalized behavioral context, the system can enforce policies across a large-scale ecosystem, such as blocking all obfuscated or packed content. The move from Karambyte to Karambiner was the architectural shift that made scanning of 14 billion files per month possible: a configurable depth of behavioral analysis, with context that scales to the size of the ecosystem rather than the capacity of individual analysis nodes. The Result: Software Behavior Analysis in Microsoft's Pipeline Today, Karambiner is integrated into Microsoft's operational pipeline for build/release and plays a critical role in performing context-aware behavioral analysis across billions of files monthly. The operational impact: Ecosystem-level behavioral policy enforcement: Obfuscated and packed content that has no legitimate reason to exist in the ecosystem is blocked by policy, informed by the scaled behavioral analysis. Durable detection under adversary adaptation: The packer_dictator lineage demonstrates that behavioral detection survives TTP changes that defeat signature-based approaches. Adversaries can change section names, rotate constants, and vary metadata, but the structural behaviors required to execute their payloads remain detectable. Low false-positive rates at scale: Because detection decisions are driven by behavioral understanding and optimizing for scale, the system maintains precision even at 14 billion files per month. Understanding AI capabilities: Behavior analysis can include understanding of where and how AI is used in an ecosystem. Deep understanding of the software going to production: Developers don't always know what components and behaviors make it to the production software, behavior analysis has allowed us to catch unexpected components developers didn’t realize were going to deployment. What's Next The partnership between Karambit.AI and Microsoft demonstrates that context-aware behavior analysis operates on a massive scale in production. As software supply chain attacks grow more sophisticated and adversaries continue evolving their TTPs and the use of AI agents to develop code, the ability to understand what software actually does, in context, across billions of files, is foundational infrastructure. Software authenticity isn't about checking a signature or trusting a certificate. It's about confirming that every binary does what it should, and nothing more. Karambit.AI is the software authenticity platform, ensuring software does only what the developer intended — nothing more. Learn more at karambit.ai.
Microsoft Leads a New Era of Software Supply Chain Transparency
Today, Microsoft announces the general availability of Microsoft’s Signing Transparency (MST) – a first-of-its-kind capability that brings unprecedented visibility and trust to our software supply chain. With this release, Microsoft is leading the industry by recording the build of critical cloud services into a publicly readable and verifiable SCITT standard (Supply Chain Integrity, Transparency, and Trust) compliant blockchain ledger. This means every production software build for in scope services like Azure Attestation and Azure Managed HSM (Hardware Security Module), Azure confidential ledger, Microsoft Signing Transparency itself (and others over time) – is now logged in an immutable, tamper-evident record. Only builds that are in the MST ledger are deployed to production; this gives customers confidence that the supply chain for these critical services can be audited at anytime. Notably, the MST ledger is fully open source and built to align with the emerging IETF SCITT standard. By embracing SCITT’s principles and open protocols, Microsoft ensures that MST not only secures our own ecosystem but also contributes to a broader industry movement toward standardized supply chain transparency. The open-source MST ledger serves as a verifiable trust anchor that any organization or researcher can inspect, audit, or even integrate with their own tooling. MST itself meets the highest levels of transparency, backed by a tamper-proof confidential ledger, open-source, and independently verified. Specifically, we are making the foundation of our trust model transparent and accessible to everyone – reinforcing that trust must be earned through proof, not just promises. This launch marks a major milestone in our commitment to Zero Trust principles, extending “never trust, always verify” all the way into the build itself. Building on a public preview introduced late last year, MST’s general availability delivers verifiable transparency at the software level. It transforms traditional code signing with an additive trust layer that is accessible via an open verification model. Every new software update is accompanied by a publicly auditable proof of integrity, enabling security teams to proactively confirm that each update is authentic and unaltered. To help organizations get the most out of this capability, we are also introducing a free tool to explore the contents – Ledger Explorer – an offline tool that allows security teams to examine MST ledger entries, verify cryptographic proofs, and even validate the ledger’s integrity independently. This tool, combined with MST’s open design, ensures that every Microsoft customer – and the broader community – can hold us accountable in real time for the software we run on their behalf. Key Benefits of Microsoft’s Signing Transparency (MST) Verified Code Integrity – Every software release is cryptographically logged in MST’s ledgers. This makes each build tamper-evident and traceable. If an attacker attempts to inject malicious code or sign an unauthorized update, it will be evident through the well-defined validation step built into the SCITT standard. Organizations gain the assurance that code integrity can be independently confirmed at any time. Independent Verification & Zero Trust – MST enables customers and auditors to verify software authenticity on their own, without having to solely rely on vendor attestations. For each update, Microsoft provides a transparency “receipt” (proof of logging) that you can use to prove the update was officially published and unaltered. This fosters a “don’t just trust, verify” approach, empowering security teams to double-check everything running in their environment aligns with what Microsoft intended. Audit-Trail & Compliance – The transparency ledger creates a permanent, auditable timeline of code deployments. Every entry is a record of what was released and when, backed by cryptographic proofs. This simplifies compliance reporting and accelerates forensic analysis. In the event of an incident, you can quickly audit the ledger to see if any unexpected code was introduced. For highly regulated industries, MST offers concrete evidence of software integrity and policy compliance over time. Leadership & Open Standards – We are delivering real transparency now, encouraging a future where all critical software is released with verifiable integrity. MST’s open source implementation and SCITT-compliant design exemplify our commitment to openness and collaboration. We believe widespread adoption of these standards will strengthen supply chain security for everyone, making trust verification a universal practice. Next Steps Microsoft’s Signing Transparency is more than a new security feature and shapes the advances in trust technology. As threats grow more sophisticated, we must evolve the way we assure our customers about the software they depend on. With MST now generally available, we are leading by example: proving that it is possible to open up the traditionally opaque process of software deployment and turn it into a source of strength and trust, i.e., empowering each person with verifiable transparency. We invite the industry to join us on this journey and get started by reading the documentation and exploring Ledger Explorer today! Together, by embracing transparency and open standards, we can turn “trust but verify” from a slogan into an everyday reality for digital infrastructure.Introducing new security and compliance add-ons for Microsoft 365 Business Premium

Today, developers are at the center of a new wave of innovation—building AI applications and agents that are deeply connected to enterprise data. But with this opportunity comes a new and complex set of security challenges. AI systems operate across cloud platforms, third-party services, and even local and on-premises development environments, interacting dynamically with sensitive data such as customer records, financial information, and intellectual property. Traditional security approaches weren’t designed for this level of scale, autonomy, or fluid data movement—leaving developers to navigate fragmented tools, unclear policies, and the risk of unintentionally exposing sensitive information. At the same time, expectations are rising. Organizations need to ensure that AI applications and agents are compliant, auditable, and secure by default on an enterprise-level—not retrofitted after deployment. But for developers, adding security often means additional complexity, custom integrations, and slower time to market. This tension between speed and control has become one of the biggest barriers to moving AI from experimentation into production. Microsoft Purview is designed to help with this challenge by embedding data security and compliance controls across the development cycle. Purview provides a consistent way to govern how data is accessed, used, and shared—without requiring developers to become security experts. The result is a simpler path to building AI systems that are secure, compliant, and enterprise-ready by design. Extending data security and compliance to local agents and claws Local and endpoint agents, built in platforms such as GitHub Copilot CLI and OpenClaw, introduce a new class of data security challenges as they operate outside traditional control planes and directly on user machines. Unlike cloud systems, these agents can access local files, credentials, terminals, and enterprise apps simultaneously—often moving data across tools and environments. This expands data risks, from sensitive data being unintentionally stored, copied, or shared, to API keys and tokens being exposed, and autonomous workflows triggering data movement without explicit user intent. At the same time, many existing security controls were designed for browser or cloud-based activity, leaving a growing blind spot at the endpoint where agents are increasingly running. The result is a widening gap between how developers build agents to operate locally in the users machines, and how organizations can detect, govern, and protect the data those agents interact with. Microsoft Security and Windows are integrating management and security capabilities directly into the local agents’ development workflow, enabling security as an architectural guarantee rather than an implementation choice. At Build, we are thrilled to be extending Purview visibility and protection capabilities to local agents developed on GitHub Copilot CLI, Claude Code, OpenAI Codex, and OpenClaw - in Public Preview. Unlike traditional cloud applications, these agents operate closer to the data and often create new risks for data exposure. Purview addresses this challenge across all types of agent interactions with a clear, simplified set of scenarios: ▪ Observability: Visibility on Purview Data Security Posture Management (DSPM) across agent inventory, as well as into how local agents interact with sensitive data—across prompts, responses, and actions. ▪ Runtime data protection: Purview Data Loss Prevention (DLP) controls enforced directly into the agent execution flow, inspecting prompts and tool calls in real time to prevent sensitive data exfiltration. ▪ Agentic risk detection: Risky or anomalous agent behaviors detected through Insider Risk Management (IRM) signals, helping teams detect unsafe interactions early. ▪ Audit: Comprehensive, end-to-end logging of all local agent interactions—capturing prompts, responses, data access, and actions for data context. For example, a developer is using a local coding agent to generate code and accidentally includes sensitive credentials in a prompt. AI observability in DSPM surfaces the interaction and shows what data the agent accessed. DLP detects the sensitive data in real time and blocks it from being sent or processed (or sensitive files from being accessed and exfiltrated). At the same time, agentic risk detection flags the session as high risk based on the behavior pattern. All of this activity is captured in audit logs, enabling the security team to investigate and take action quickly. Developers and security teams gain visibility into agent activity and data interactions, while policies prevent sensitive data leakage. This ensures consistent security outcomes across both cloud and endpoint environments, without disrupting developer workflows. Strengthening visibility and controls for Foundry agents Foundry gives developers a central place to build and manage AI agents, but it also creates a need for data security context directly in that workflow—especially as prompts, model interactions, and downstream actions increasingly involve sensitive enterprise data. At Build, we are excited to announce the expansion of the Foundry integration with Purview. This includes Purview DLP runtime controls for prompt processing in Foundry, in Public Preview. As agents and applications built on Foundry increasingly interact with sensitive data, Purview ensures those interactions are governed by trusted controls, identifying Sensitive Information Types (SITs) in real time to detect and protect confidential data embedded in prompts. For example, if a user includes customer PII or financial data in a prompt, Purview can automatically identify the sensitive content and block that prompt from being processed by the model. This ensures that all Foundry apps and agents, regardless of how they’re built or deployed, inherit consistent data protection – allowing organizations to reduce risk of inadvertent data exposure, centralize compliance enforcement across AI workloads, and confidently scale AI adoption knowing sensitive data is protected by design. We’re also building up on the Purview coverage for Foundry shared at the last Microsoft Ignite by announcing Purview insights embedded directly into the Foundry Control Plane, in General Availability, bringing rich data security context to the plane where developers already work. Purview surfaces crucial signals—such as SITs detected in the agentic interactions, % of agentic interactions involving sensitive data, and spread of high-risk users — so Foundry admins can know how AI apps and agents are built in their environment. This shift enables developers to make faster, better decisions in the moment, reducing rework and closing security gaps early on. For customers, the value is clear: stronger security by design and at enterprise scale, accelerated development cycles, and reduced risk of data leaks or compliance issues—without slowing down innovation. Innovating for developers everywhere, at the pace of AI growth Microsoft is also expanding Purview’s reach across the broader developer ecosystem. New integrations help organizations apply consistent oversight to AI tools and platforms developers already use, without adding separate compliance workflows. GitHub Copilot is a critical productivity layer for developers, accelerating how code is written and shipped—making it equally important that developer interactions with GitHub Copilot are governed and secured with the same rigor as enterprise data. Microsoft Purview now extends data governance and compliance capabilities to GitHub Copilot interactions, in Public Preview, enabling GitHub Enterprise customers with Entra SSO to stream audit logs directly into Purview. This brings centralized visibility for AI activity, allowing security and compliance teams to analyze GitHub Copilot agent session activity alongside other AI workloads. With this native integration into GitHub workflows, Purview audits Copilot activity across repositories, pull requests, and developer sessions—ensuring AI-generated code aligns with enterprise data policies, compliance requirements, and secure development standards. By integrating Purview into existing workflows, organizations can govern GitHub AI usage without building parallel pipelines—reducing complexity while ensuring consistent compliance coverage across their entire data estate. Today’s AI agents aren’t built in just one ecosystem—they span custom apps, third-party platforms, and open-source frameworks. Without consistent controls, this creates blind spots where sensitive data can be exposed outside enterprise guardrails. That’s why extending Purview protection beyond Microsoft environments is critical: it ensures developers can apply the same data security, DLP policies, and compliance controls to any agent, anywhere—so innovation can scale without increasing risk. Developers already use Microsoft Purview APIs to embed data protection into enterprise workflows. Today, we’re introducing the Microsoft Purview SDK for .NET — a simple, drop-in toolkit that brings Purview capabilities directly into any application, in Public Preview. Instead of weeks spent wiring APIs, authentication, and error handling, developers can add content scanning, DLP checks, and sensitivity labeling in just a few lines of code. The SDK handles the heavy lifting — including auth, retries, caching, and telemetry — so teams can focus on building experiences. For AI apps and agents built outside of the Microsoft AI platforms, SDK adds built-in support and can evaluate prompts and responses in real time against DLP and content policies — helping prevent data exposure at runtime without custom logic. Designed for both real-time and asynchronous patterns, and for authenticated or anonymous flows, the SDK also feeds activity back into Purview to give security teams centralized visibility and control. The bottom line is- the Microsoft Purview SDK enables developers to build AI apps and agents that are secure and compliant by default — cutting integration time from weeks to days while ensuring data protection scales with AI. The SDK will be available in public preview within the next month. Together, these announcements represent a significant step forward in how developers build secure AI systems. Microsoft Purview is no longer just a data security and compliance solution—it is a first-class layer of the development process by protecting data across AI applications and agents, and enables a bridge between developers and security teams. As AI becomes more agentic, distributed, and deeply connected to enterprise data, the need for built-in security will only grow. With Purview, developers no longer must choose between speed and security—they can build both into every application from the start Getting connected with Microsoft Purview and learn more Learn more about Microsoft Purview on our website and Microsoft Learn.

AI is reshaping the enterprise and, with it, the threat landscape. Today's organizations face new threats with AI agents that modify configurations, execute workflows, and access data without direct human oversight. As a result, the gap between AI adoption and AI governance is widening, and CISOs face growing challenges to maintain visibility, control, and compliance across an increasingly complex ecosystem. As AI becomes embedded across the enterprise, CISOs face four key challenges: Scale without visibility: Over 75% of enterprises surveyed by PWC report they are already adopting AI agents. ¹ At the same time, over 80% of security teams surveyed by Nokod report visibility gaps into the applications and AI agents created within their organization. ² Rapid AI proliferation and evolving regulations make unified visibility across AI platforms, apps, and agents critical for CISOs. Fragmentation: Organizations rely on multiple siloed tools for AI asset visibility, making oversight fragmented and inefficient. According to Gartner’s 2024 survey of 162 enterprises, organizations use 45 cybersecurity tools on average. Expanding AI risk: AI proliferation is rapidly increasing the attack and risk surface, with the surge of AI-generated identities. By 2027, 4 out of 5 organizations will face phishing attacks powered by AI-generated synthetic identities, according to IDC. ³ This makes it harder for CISOs to track emerging threats, unmanaged assets, and shifting risk patterns. Overload: Alert fatigue is now a top challenge, with organizations now receiving an average of 2,992 security alerts daily, yet 63% go unaddressed. ⁴ Increasing AI risk without a way to prioritize what matters most compounds pressure on CISOs. In conversations between Microsoft and CISOs, one common need emerged: a single place to view integrated AI risk across the enterprise. To address these growing challenges, we are excited to provide CISOs with the Security Dashboard for AI, which recently became generally available. This unified dashboard aggregates posture and real-time risk signals from Microsoft Defender, Entra, and Purview into one unified, executive-level view of AI posture, risk, and inventory across agents, apps, and platforms. The Security Dashboard for AI helps CISOs: Gain unified AI risk visibility: Discover AI agents and applications and continuously monitor posture across the environment Prioritize critical risks: Correlate signals across identity, data, and threat protection to surface the most urgent issues Drive risk mitigations: Investigate activity and take action to help reduce exposure across the AI ecosystem The dashboard is capable of aggregating and surfacing AI risks from across Microsoft Defender, Entra, Purview - including Microsoft 365 Copilot, Microsoft Copilot Studio agents, and Microsoft Foundry applications and agents as well as cross-platform AI risks with Microsoft network-based or SDK-enabled integrations, and MCP servers. This supports comprehensive visibility and control, regardless of where applications and agents are built. As you activate Microsoft Security for AI capabilities, you can gain richer visibility into different aspects of your AI risk posture. Figure 1: Security Dashboard for AI in browser Getting Started with the Security Dashboard for AI The Security Dashboard for AI is provided at no additional cost to customers already using Defender, Entra, and/or Purview to protect their AI innovation. Based on how early adopter CISOs are using the dashboard, here are three ways you can start leveraging the dashboard today. 1. Manage Daily AI Risk Beyond reporting, you must stay hands-on with AI risks, scanning for emerging issues, verifying asset governance, and delegating remediations. The Security Dashboard for AI consolidates daily operations into a single pane of glass, surfacing critical alerts, unmanaged assets, and emerging risks. Use the dashboard as a daily AI risk radar, enabling rapid triage and ensuring you focus on the most urgent threats. Scan and triage daily AI risk: Start each day by identifying and prioritizing the highest-risk AI exposures. Risks are prioritized on severity reported by underlying security tools, helping you focus on the most critical exposures. Track AI asset inventory and monitor agent sprawl: Use the Inventory page to gain comprehensive visibility into all AI assets. Identify newly registered assets to mitigate the risk of shadow or unmanaged IT and surface inactive agents to proactively monitor and control agent sprawl. Delegate tasks for remediation: Move from insight to action by delegating tasks to your security team with easy click delegation. Delegation routes ownership via email or Microsoft Teams with notifications, due date, and ownership tracking. Delegate actions to specific roles such as global admin and AI administrator, without granting full access to underlying tools. Figure 2: Security Dashboard for AI risk page 2. Guide Briefings with Security Teams You require up-to-date intelligence to guide conversations with Security Teams about what is happening across the AI estate. The Security Dashboard for AI helps you anchor discussions in specific risks, trends, and ownership gaps surfaced in the data. The dashboard becomes a conversation driver, helping you ask the right questions about risk and security posture, to help ensure you and your team are triaging the right priorities. Because the dashboard consolidates signals from Defender, Entra, and Purview, both CISO and security teams operate from the same facts, enabling more outcome-driven discussions and faster prioritization, so you can shift the conversations from status updates to targeted action planning. Prioritize top AI Risk: Use the dashboard to help you prioritize the AI risk that matters the most. In preparation for team meetings, use Microsoft Security Copilot to explore AI risks, agent activity, and security recommendations via prompts to strengthen your AI security posture. With your team, take a closer look at risk vectors like data leakage, oversharing and unethical behavior, and discuss what actions need to be taken. Review Security Recommendations: Create a routine with your security team to review the recommended Microsoft security actions and track your progress over time. Across regular team check‑ins, review what has been addressed, what remains open, and which actions require follow‑up so you are prepared to respond to regulatory, audit, or executive questions with up‑to‑date metrics. Figure 3: Security Dashboard for AI inventory page Figure 4: Security Dashboard for AI delegation 3. Executive Reporting Reporting to the board on AI security posture has historically meant weeks of manual data gathering across multiple tools. The Security Dashboard for AI streamlines the data collection process with a single source of truth for AI risk, enabling confident, data-backed insights for your board presentations and conversations. Early adopters confirm the value and are using it for quarterly executive briefings. Prepare for Board Discussions: Use the dashboard to help get the right insights at the right altitude to help you prepare for discussions with your board. The Overview page aggregates identity, data security, and threat protection signals from Defender, Entra, and Purview into an AI risk scorecard with risk factors. The embedded Security Copilot AI-powered insights provide suggested prompts with risk assessments, summaries, and recommendations to help you prioritize what matters most. Extend Observability to Executive Stakeholders: Authorize AI risk follow‑ups to the appropriate security, identity, or governance owners using Microsoft Teams or email. Distribute visibility across GRC lead, AI governance, and IT leaders, while maintaining executive‑level oversight. Figure 5: Security Dashboard for AI Copilot prompt gallery Next Steps The Security Dashboard for AI helps CISOs manage AI risk faster, more confidently and more collaboratively with their team. Defender, Entra, and Purview signals are surfaced in a single pane of glass, providing observability across your AI estate. Drive faster triage, use data to support board-level discussions about AI risk, and enable coordinated action with integrated insights, recommendations, and delegation to help accelerate remediation across existing security workflows. The Security Dashboard for AI is generally available now. If your organization uses Microsoft Defender, Entra, and/or Purview, you already have access, no additional licensing is required.

Vectra AI, February 2026Security Dashboard for AI - Now Generally Available
AI proliferation in the enterprise, combined with the emergence of AI governance committees and evolving AI regulations, leaves CISOs and AI risk leaders needing a clear view of their AI risks, such as data leaks, model vulnerabilities, misconfigurations, and unethical agent actions across their entire AI estate, spanning AI platforms, apps, and agents. 53% of security professionals say their current AI risk management needs improvement, presenting an opportunity to better identify, assess and manage risk effectively. 1 At the same time, 86% of leaders prefer integrated platforms over fragmented tools, citing better visibility, fewer alerts and improved efficiency. 2 To address these needs, we are excited to announce the Security Dashboard for AI, previously announced at Microsoft Ignite, is now generally available. This unified dashboard aggregates posture and real-time risk signals from Microsoft Defender, Microsoft Entra, and Microsoft Purview - enabling users to see left-to-right across purpose-built security tools from within a single pane of glass. The dashboard equips CISOs and AI risk leaders with a governance tool to discover agents and AI apps, track AI posture and drift, and correlate risk signals to investigate and act across their entire AI ecosystem. Security teams can continue using the tools they trust while empowering security leaders to govern and collaborate effectively. Gain Unified AI Risk Visibility Consolidating risk signals from across purpose-built tools can simplify AI asset visibility and oversight, increase security teams’ efficiency, and reduce the opportunity for human error. The Security Dashboard for AI provides leaders with unified AI risk visibility by aggregating security, identity, and data risk across Defender, Entra, Purview into a single interactive dashboard experience. The Overview tab of the dashboard provides users with an AI risk scorecard, providing immediate visibility to where there may be risks for security teams to address. It also assesses an organization's implementation of Microsoft security for AI capabilities and provides recommendations for improving AI security posture. The dashboard also features an AI inventory with comprehensive views to support AI assets discovery, risk assessments, and remediation actions for broad coverage of AI agents, models, MCP servers, and applications. The dashboard provides coverage for all Microsoft AI solutions supported by Entra, Defender and Purview—including Microsoft 365 Copilot, Microsoft Copilot Studio agents, and Microsoft Foundry applications and agents—as well as third-party AI models, applications, and agents, such as Google Gemini, OpenAI ChatGPT, and MCP servers. This supports comprehensive visibility and control, regardless of where applications and agents are built. Prioritize Critical Risk with Security Copilots AI-Powered Insights Risk leaders must do more than just recognize existing risks—they also need to determine which ones pose the greatest threat to their business. The dashboard provides a consolidated view of AI-related security risks and leverages Security Copilot’s AI-powered insights to help find the most critical risks within an environment. For example, Security Copilot natural language interaction improves agent discovery and categorization, helping leaders identify unmanaged and shadow AI agents to enhance security posture. Furthermore, Security Copilot allows leaders to investigate AI risks and agent activities through prompt-based exploration, putting them in the driver’s seat for additional risk investigation. Drive Risk Mitigation By streamlining risk mitigation recommendations and automated task delegation, organizations can significantly improve the efficiency of their AI risk management processes. This approach can reduce the potential hidden AI risk and accelerate compliance efforts, helping to ensure that risk mitigation is timely and accurate. To address this, the Security Dashboard for AI evaluates how organizations put Microsoft’s AI security features into practice and offers tailored suggestions to strengthen AI security posture. It leverages Microsoft’s productivity tools for immediate action within the practitioner portal, making it easy for administrators to delegate recommendation tasks to designated users. With the Security Dashboard for AI, CISOs and risk leaders gain a clear, consolidated view of AI risks across agents, apps, and platforms—eliminating fragmented visibility, disconnected posture insights, and governance gaps as AI adoption scales. Best of all, the Security Dashboard for AI is included with eligible Microsoft security products customers already use. If an organization is already using Microsoft security products to secure AI, they are already a Security Dashboard for AI customer.

The Connected Risk Report: Uniting Teams and Insights to Drive Organizational Resilience. AuditBoard, October 2024. 2Microsoft. 2026 Data Security Index: Unifying Data Protection and AI Innovation. Microsoft Security, 2026The Advantages of Premium Cases in Purview eDiscovery
Capacity & Scale Feature Description Advantage over E3 Enhanced Limits Supports significantly higher limits, including eDiscovery case count and export volume. For example, up to 50,000 cases and 5 TB per search in E5 (versus 10,000 cases and 2 TB in E3). Handles large investigations without splitting into multiple cases or searches. E3’s lower limits would force breaking up big jobs, adding overhead and risk of errors. E5’s higher capacity means fewer workarounds and seamless handling of large-scale litigation. Tenant-Wide eDiscovery Process and Holds Reports (Preview) Provides a central dashboard of all eDiscovery activities and eDiscovery holds across the tenant. Compliance and IT teams get at-a-glance status of ongoing jobs and active holds. Improves oversight and management efficiency for eDiscovery. E3 lacks centralized reporting, making it harder to track many cases. E5’s reporting gives better visibility into operations, which is crucial for heavy workloads and tight deadlines. Expanded Hold Capacity Each legal hold in E5 can encompass up to 2,000 mailboxes and 2,000 sites in one policy. E3 holds are limited to 1,000 mailboxes or 100 sites per policy. Enables placing very large custodian sets on hold with a single action. In E3, exceeding hold limits means juggling multiple policies for one case, increasing complexity. E5 simplifies hold management by consolidating more custodians per hold, reducing admin burden. Search & Collection Feature Description Advantage over E3 Advanced Search Filters Offers richer search criteria beyond keywords. You can filter by sensitive info types (credit cards, SSNs), specific message IDs, or sensitivity labels on documents. This helps pinpoint relevant sensitive content directly. Enables more precise and speedy discovery of critical data. In E3, finding the same info might require complex keyword strings or separate tools (with a higher chance of missing items). E5’s advanced filters mean faster, targeted searches for things like confidential data or GDPR content. Data Source Sync Allows you to refresh custodians’ data sources in a search or hold to catch updates to locations. For example, if a custodian adds a new OneDrive, E5 will detect and prompt you to include it. Ensures no content location is overlooked as the case evolves. E3 has no easy way to know if data moved or new sites were created, potentially leaving gaps. E5’s sync provides complete and defensible collection by keeping holds/searches up-to-date. Cloud Attachment Collection (Hyper-linked Documents) Automatically collects the content of files shared via cloud links (OneDrive/SharePoint) in emails or chats. E5 can retrieve the actual document (and its versions) that was linked, even pulling the specific version that was shared at the time if the version shared feature is enabled. Preserves evidence that E3 would miss. E3 eDiscovery does not fetch linked file content. It would only show a hyperlink, making it difficult to return the associated file. E5 ensures linked documents (with version history) are collected, so the full context of communications is retained. Conversation Threading (Chats & Email) Reconstructs conversations in a threaded view for Microsoft Teams chats and email chains. Reviewers can see messages in context (like a chat transcript or email thread) rather than as isolated items. Greatly improves contextual understanding. E3 exports chats as separate messages with no threading, making it hard to follow the story. E5’s threaded view lets reviewers grasp the full conversation at a glance, reducing confusion and ensuring nothing is interpreted out of context. Custodian & Hold Management Feature Description Advantage over E3 Case-Level Custodian Management Provides a dedicated tab to manage custodians (people) within each case. You add custodians once and can easily apply holds or searches to all their data without re-entering their information each time. Streamlines hold setup and ensures clarity on who is in the case. E3 has no concept of custodians. You must manually input email or site addresses for each search/hold. E5’s approach saves time, reduces errors, and gives a clear view of all people involved in the matter. Bulk Custodian Import Supports importing up to 1,000 custodians at once from a list into a case. Useful for large investigations (e.g., adding an entire department as custodians in one go). Dramatically faster setup for big cases. In E3, adding hundreds of people means typing or pasting each individually, which is time-consuming and error prone. E5’s bulk import means quick, one-time setup for large custodian lists, ensuring no one is missed. “Explore & Add” Custodian Sources Provides an intelligent way to discover related data sources for a given custodian. For example, it can list Teams, SharePoint sites, or groups the person is part of, and let you add those to the case. Helps capture all relevant locations for each person. In E3, you might overlook a Teams channel or group mailbox a custodian was involved in. E5’s explore feature surfaces those connections, improving completeness of your holds and searches by including collaboration spaces that might otherwise be missed. In-Place Review & Analytics Feature Description Advantage over E3 Advanced Indexing and OCR Automatically re-indexes content that was partially indexed or had errors and performs OCR (Optical Character Recognition) on images to extract text. This means files with images or previously unsearchable formats become searchable in E5. Ensures “no stone is left unturned.” E3 would flag such content as “unindexed” (meaning you know a file exists but not what’s inside it). With E5, far more data is searchable, even text inside images or scanned PDFs, reducing the amount of partially indexed content and the chance of missing critical evidence due to format issues. In-Place Review Sets Lets you create a review set of collected data in the cloud. Review sets offer contextual review of conversations, powerful query and filtering capabilities, and query reports for additional insights. Pre-review culling is possible in E5. E3 has no in-product review capability. You must export everything to an outside tool for examination. E5’s review sets allow the team to filter out irrelevant data and focus on what matters before exporting. This reduces the volume (and cost) of data sent for attorney review and keeps data in a secure, auditable environment during analysis. Tagging and Metadata Filters Enables applying tags (labels like “Responsive,” “Privileged,” “Personal Data”) to documents and emails in a review set, and filtering by these tags or other metadata fields. Improves organization and review workflow. E3 cannot tag items in-place, so keeping track of important documents is harder. In E5, tagging allows systematic categorization for quick retrieval (e.g., find all items tagged Highly Relevant instantly). These tags also carry over on export, so any work done during review isn’t lost when handing off to external counsel. Email Threading and Analytics Automatically identifies and stitches together email threads, showing only the last inclusive email that contains the entire conversation. Earlier duplicate emails in the chain are noted and can be skipped. Cuts down review volume and improves context. E3 reviewers would see every single email (even if content repeats across replies). This saves review time and ensures attorneys see the full discussion in one place rather than piecemeal. Conversation View Displays collected Teams (and other chat) messages in a conversation format in a review set, similar to how one would view a chat in the app, instead of individual out-of-context messages. Makes reviewing chat evidence much easier. In E3, chat messages are isolated, forcing reviewers to manually piece together who said what when. E5’s conversational view provides full context at a glance, so nothing is misunderstood or missed in chat-based communications. Near-Duplicate Detection Finds and groups nearly identical documents (e.g. multiple versions of a file or emails with only slight differences). Reviewers are informed which items are alike. Saves time and ensures consistency. E3 requires manually spotting similar files. E5 can let a reviewer examine one version and then quickly tag all its close duplicates the same way. This speeds up review and ensures similar content is handled uniformly (no conflicting judgments on essentially the same document). Themes (Topic Analytics) Uses analytics to cluster documents by themes/topics. For example, it might reveal a group of emails all discussing “Project X” or detect an unusual theme (like frequent mentions of “resignation”). Uncovers hidden patterns that simple keyword searches in E3 might miss. This insight helps investigators spot important threads of discussion or issues they weren’t explicitly searching for, leading to a more thorough understanding of the data set. It adds a layer of proactive insight absent in E3. Global Deduplication Automatically de-duplicates exact copies of emails or files across all custodians using review sets. Each unique item is retained once for review, with duplicates noted. Prevents redundant review work. In E3, the same email stored in five mailboxes would appear five times and could be reviewed and tagged inconsistently by different people. E5’s deduplication means reviewers spend time only on unique content improving efficiency and ensuring consistency in treatment of identical items. Export & Integration Feature Description Advantage over E3 Guest Reviewer Access Allows secure, read-only external access to a review set for outside experts (like outside counsel). Guest reviewers can be invited to review and tag documents in your E5 case via secure Azure AD access (with MFA), without data leaving the tenant. Enables collaboration with outside counsel without exporting data. E3 cannot extend access to external users. You’d have to export files and send them out, which is slower and riskier. E5 keeps the data in-place and governed, letting external reviewers work more efficiently while your organization retains control and visibility. Import External Data Supports ingestion of data from outside M365 into eDiscovery. You can load files like PST emails, PDFs, or documents from file shares into an E5 review set, maintaining custodians’ identity and metadata. Brings all relevant data under one roof. E3 cannot handle content beyond Exchange/SharePoint/Teams, so any non-M365 data would be reviewed separately. E5’s ingestion means even file server or third-party data can be included in the case, making your eDiscovery truly comprehensive and eliminating blind spots between different systems. Rich Export with Metadata Exports include a detailed load file with extensive metadata from the review (custodian info, email thread indices, attachment names, message IDs, tags applied, etc.). This is in addition to the actual content files. Simplifies downstream processing and preserves review decisions. E3’s export is basic (limited metadata), often requiring additional data processing in third-party tools. E5’s comprehensive load file means that all important context (including tags like “Privileged” that your team applied) travels with the exported data, so external reviewers immediately see those cues. This saves time and prevents rework. MIP Search and Decryption Integration Can automatically decrypt protected content (encrypted by Microsoft Information Protection, e.g. with sensitivity labels/Azure RMS) during eDiscovery. Encrypted emails and documents are made readable and searchable when added to a review set. Ensures encrypted files aren’t “invisible” in your investigation. E3 often cannot search or preview MIP-protected emails/docs until they’re manually decrypted after export (if at all). E5 seamlessly includes these encrypted items in search results and review, so you don’t miss evidence that was simply locked behind encryption. Insider Risk Management Escalation Integrates with Microsoft Insider Risk Management (IRM) alerts. With E5, if an insider risk policy flags a user (e.g., for a potential data theft), you can one-click escalate to create an eDiscovery case that automatically targets that user’s content around the incident. Enables a fast, seamless response to insider threats. E3 has no IRM at all, so there’s no such trigger. In E5, the moment a high-risk activity is detected, the legal team can immediately jump into collecting and reviewing the related data. This tight integration means quicker investigations and potentially mitigating issues before they escalate. Communication Compliance Escalation Ties into Communication Compliance (E5’s internal communications monitoring for policy violations). If a serious policy violation is found (e.g., harassment in Teams chats or inappropriate sharing of sensitive info), it can be escalated directly into an eDiscovery case for further investigation. Offers proactive discovery of misconduct. E3 lacks built-in communication monitoring, so issues may go unnoticed until too late. With E5, compliance officers can swiftly pivot from detecting a problem to launching a full eDiscovery inquiry, ensuring faster and more thorough handling of incidents like HR violations or data leaks. Graph API & Automation Fully supports the Microsoft Graph API for eDiscovery. This means eDiscovery tasks (case creation, adding custodians, running searches, exporting data) can be automated or integrated into other applications via scripting/programming without additional cost. While API support is supported for E3, the E3 export API is a metered solution. E5 allows organizations to streamline eDiscovery workflows – for example, auto-create a case and hold when HR flags an employee exit, or integrate with third-party legal management tools without additional cost. Teams and Copilot Interactions Purge Provides an incident response capability to search and purge Teams chats or Microsoft 365 Copilot interactions if sensitive information was shared. Authorized investigators can directly delete up to 100 Teams chat messages (across participant mailboxes) in one go via the eDiscovery interface (leveraging Graph API) when necessary to contain a data leak. Allows quick containment of spills that E3 cannot do. E3’s content search can purge emails but cannot delete Teams messages or Copilot content. With E5, if confidential data pops up in a Teams chat, compliance can not only find it but also bulk-delete those messages from user mailboxes to mitigate further exposure. This capability is crucial for responding to internal data mishandling in real time.Collecting Microsoft 365 Copilot Data with Microsoft Purview eDiscovery

This will automatically pull into the export or review set any Facilitator agent meeting notes. Facilitator created word/loop documents SharePoint Online: When the facilitator agent is asked to create a word or loop document during a meeting they are stored in the requesters OneDrive in a folder called N/A These are SharePoint files (not Exchange items), so no item class applies. Identify them in search results by the .loop file extension. 1. Add the user's OneDrive URL as a data source to the search. 2. In the condition builder you can optionally filter the search to only return loop and doc files by adding a condition of "File type equals any of loop, docx". 3. Add any further additional conditions such as date range or keywords to narrow results as required. Notes: · With eDiscovery premium enabled cases you can follow the standard workflow for collecting Team meeting messages and select to include cloud attachments in your collection. This will automatically pull into the export or review set any Facilitator generated loop or word documents. Facilitator generated and assigned tasks Exchange Online: When the facilitator agent creates and assigns a task to an individual, it is created as a to-do item in the assigned individual's Exchange Mailbox IPM.Task 1. Add the user's Exchange mailbox as a data source to the search. 2. In the condition builder you can optionally filter the search to only return Tasks by adding a condition of "Item class contains any of Tasks". 3. Add any further additional conditions such as date range or keywords to narrow results as required. Application-Specific Item Classes for Prompts & Responses For more granular filtering by Copilot application, the following item class values can be used in KQL queries: Application Context Item Class Value Microsoft Copilot Chat (BizChat / Teams) IPM.SkypeTeams.Message.Copilot.BizChat Copilot in Excel IPM.SkypeTeams.Message.Copilot.Excel Copilot in Loop IPM.SkypeTeams.Message.Copilot.Loop Copilot in Outlook IPM.SkypeTeams.Message.Copilot.Outlook Copilot in PowerPoint IPM.SkypeTeams.Message.Copilot.PowerPoint Copilot in Teams IPM.SkypeTeams.Message.Copilot.Teams Copilot in Whiteboard IPM.SkypeTeams.Message.Copilot.Whiteboard Copilot in Word IPM.SkypeTeams.Message.Copilot.Word To target all Copilot applications at once, use the wildcard query ItemClass:IPM.SkypeTeams.Message.Copilot.*. For a wider list of AI data sources, see the following link: https://learn.microsoft.com/en-us/purview/edisc-search-copilot-data#data-sources-for-ai-data Important Notes for eDiscovery Practitioners Excluding Copilot Data from Broader Searches Because Copilot prompts and responses reside in the same Exchange mailbox as emails and Teams chats, they will appear in broad mailbox searches unless explicitly filtered out. To exclude Copilot items, use the condition "Item Class Contains none of Copilot activity" in the condition builder, or add (-ItemClass:IPM.SkypeTeams.Message.Copilot.*) in KQL. Some eDiscovery managers run separate searches, one for Copilot data and one for other communications, to keep collections distinct. Copilot Memories: Retention & Hold Limitations Purview retention policies and eDiscovery holds do not currently apply to Copilot memory items. Memory items remain until a user deletes them or an admin explicitly removes them via eDiscovery or Graph API. Additionally, deleting a Copilot prompt and response does not delete any memory derived from that conversation. Memories must be removed separately if required. Copilot Pages: Do Not Treat Like Prompts/Responses Copilot Pages are not stored in Exchange mailboxes. Searching only a custodian’s mailbox will not return Copilot Pages. Treat Copilot Pages the same way as you do for SharePoint content in your existing eDiscovery workflow. For collections, keyword searches will generate hits on text content within the .page file if either the SharePoint Embedded URL is included in the search or the search is a tenant-wide search of all SharePoint sites Be aware that full-text search within .page files in Purview eDiscovery review sets is not currently available. Instead you can use filters such as Subject/Title or Native File Type to locate Copilot Pages in your review set and review the content. When an eDiscovery hold is placed on a custodian’s mailbox, it does not automatically extend to the SharePoint Embedded site where the Copilot Pages are stored. Instead, ensure the hold policy includes the URL for the user-owned SharePoint Embedded site that contains the Copilot Page(s) that must be preserved. Audit Logs vs. eDiscovery for Copilot Content Audit logs record that a Copilot interaction occurred (time, user, workload context) but do not include the actual prompt or response text. To retrieve the substance of Copilot interactions, use Purview eDiscovery searches against the mailbox. Copilot Prompts and Responses: HTML Transcription Copilot prompts and responses are stored as individual messages within the user’s mailbox. When collecting Copilot interactions, enabling the “Organize conversations into HTML transcripts” premium option will convert these individual messages into HTML transcripts making for easier review and linkage between the user’s original prompt and the Copilot responses. Copilot Prompts and Responses: Contextual prompts and responses When using the Keywords condition as part of your collection in eDiscovery, it will only return items that match the keywords included in the query. This means that you may only return a part of the Copilot interaction. If using keywords in your collection query you can enable the “Include full conversation for Copilot, Teams and Viva Engage messages” premium option. This will include in the export or review set any prompts or responses from the Copilot interaction within a 12-hour window before and after each responsive item. This means that you are able to see the full context of the prompt or response that was responsive to search. Collecting Referenced Documents (Cloud Attachments) Copilot responses may reference or summarize SharePoint/OneDrive files. When collecting Copilot interactions, enabling the "Access links (cloud attachments) in messages" premium option will additionally collect the files referenced in the prompt or response and include them in the export package. This provides full evidentiary context but can significantly increase export size and processing time so consider if collecting these artifacts are relevant to the investigation. If so, look to use additional conditions such as date to effectively manage volumes or reduce the number of custodians in the collection. Facilitator agent in Microsoft Teams Meetings The Facilitator agent in Microsoft Teams is an AI-powered assistant (included with Microsoft 365 Copilot) that enhances meeting productivity by generating real-time notes, summarizing key decisions, and managing action items. It acts as an active participant, allowing for collaborative editing of notes and answering chat questions during calls. As the Facilitator works within the context of Microsoft Teams meetings (scheduled private meetings only) your existing workflows for collecting Microsoft Teams meetings chat should be used. In addition, enabling the "Access links (cloud attachments) in messages" premium setting will automatically collect any meeting note (loop) or loop or word documents created by the Facilitator agent.
