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.Extracting and Auditing Azure DevOps Permissions at Scale with PowerShell
Managing access in Azure DevOps is easy at small scale — and increasingly opaque as organizations grow. This post introduces ADO Permissions Output, an open-source PowerShell toolset that queries Azure DevOps REST APIs across 30+ security namespaces, decodes bitmask permissions, resolves cryptic GUIDs and tokens into readable names, and produces structured JSON/CSV output ready for Power BI. It also surfaces "ghost" members — users who appear in ADO through nested Entra groups but hold no active entitlement — which the standard Graph API alone cannot detect. Whether you're preparing for a compliance review or just want to know who actually has access to what, this tool closes the gap between the ADO portal and a complete audit picture.Why UK Enterprise Cybersecurity Is Failing in 2026 (And What Leaders Must Change)
Enterprise cybersecurity in large organisations has always been an asymmetric game. But with the rise of AI‑enabled cyber attacks, that imbalance has widened dramatically - particularly for UK and EMEA enterprises operating complex cloud, SaaS, and identity‑driven environments. Microsoft Threat Intelligence and Microsoft Defender Security Research have publicly reported a clear shift in how attackers operate: AI is now embedded across the entire attack lifecycle. Threat actors use AI to accelerate reconnaissance, generate highly targeted phishing at scale, automate infrastructure, and adapt tactics in real time - dramatically reducing the time required to move from initial access to business impact. In recent months, Microsoft has documented AI‑enabled phishing campaigns abusing legitimate authentication mechanisms, including OAuth and device‑code flows, to compromise enterprise accounts at scale. These attacks rely on automation, dynamic code generation, and highly personalised lures - not on exploiting traditional vulnerabilities or stealing passwords. The Reality Gap: Adaptive Attackers vs. Static Enterprise Defences Meanwhile, many UK enterprises still rely on legacy cybersecurity controls designed for a very different threat model - one rooted in a far more predictable world. This creates a dangerous "Resilience Gap." Here is why your current stack is failing- and the C-Suite strategy required to fix it. 1. The Failure of Traditional Antivirus in the AI Era Traditional antivirus (AV) relies on static signatures and hashes. It assumes malicious code remains identical across different targets. AI has rendered this assumption obsolete. Modern malware now uses automated mutation to generate unique code variants at execution time, and adapts behaviour based on its environment. Microsoft Threat Intelligence has observed threat actors using AI‑assisted tooling to rapidly rewrite payload components, ensuring that every deployment looks subtly different. In this model, there is no reliable signature to detect. By the time a pattern exists, the attacker has already moved on. Signature‑based detection is not just slow - it is structurally misaligned with AI‑driven attacks. The Risk: If your security relies on "recognising" a threat, you are already breached. By the time a signature exists, the attacker has evolved. The C-Suite Pivot: Shift investment from artifact detection to EDR/XDR (Extended Detection and Response). We must prioritise behavioural analytics and machine learning models that identify intent rather than file names. 2. Why Perimeter Firewalls Fail in a Cloud-First World Many UK enterprise still rely on firewalls enforcing static allow/deny rules based on IP addresses and ports. This model worked when applications were predictable and networks clearly segmented. Today, enterprise traffic is encrypted, cloud‑hosted, API‑driven, and deeply integrated with SaaS and identity services. AI‑assisted phishing campaigns abusing OAuth and device‑code flows demonstrate this clearly. From a network perspective, everything looks legitimate: HTTPS traffic to trusted identity providers. No suspicious port. No malicious domain. Yet the attacker successfully compromises identity. The Risk: Traditional firewalls are "blind" to identity-based breaches in cloud environments. The C-Suite Pivot: Move to Identity-First Security. Treat Identity as the new Control Plane, integrating signals like user risk, device health, and geolocation into every access decision. 3. The Critical Weakness of Single-Factor Authentication Despite clear NCSC guidance, single-factor passwords remain a common vulnerability in legacy applications and VPNs. AI-driven credential abuse has changed the economics of these attacks. Threat actors now deploy adaptive phishing campaigns that evolve in real-time. Microsoft has observed attackers using AI to hyper-target high-value UK identities- specifically CEOs, Finance Directors, and Procurement leads. The Risk: Static passwords are now the primary weak link in UK supply chain security. The C-Suite Pivot: Mandate Phishing‑resistant MFA (Passkeys or hardware security keys). Implement Conditional Access policies that evaluate risk dynamically at the moment of access, not just at login. Legacy Security vs. AI‑Era Reality 4. The Inherent Risk of VPN-Centric Security VPNs were built on a flawed assumption: that anyone "inside" the network is trustworthy. In 2026, this logic is a liability. AI-assisted attackers now use automation to map internal networks and identify escalation paths the moment they gain VPN access. Furthermore, Microsoft has tracked nation-state actors using AI to create synthetic employee identities- complete with fake resumes and deepfake communication. In these scenarios, VPN access isn't "hacked"; it is legally granted to a fraudster. The Risk: A compromised VPN gives an attacker the "keys to the kingdom." The C-Suite Pivot: Transition to Zero Trust Architecture (ZTA). Access must be explicit, scoped to the specific application, and continuously re‑evaluated using behavioural signals. 5. Data: The High-Velocity Target Sensitive data sitting unencrypted in legacy databases or backups is a ticking time bomb. In the AI era, data discovery is no longer a slow, manual process for a hacker. Attackers now use AI to instantly analyse your directory structures, classify your files, and prioritise high-value data for theft. Unencrypted data significantly increases your "blast radius," turning a containable incident into a catastrophic board-level crisis. The Risk: Beyond the technical breach, unencrypted data leads to massive UK GDPR fines and irreparable brand damage. The C-Suite Pivot: Adopt Data-Centric Security. Implement encryption by default, classify data while adding sensitivity labels and start board-level discussions regarding post‑quantum cryptography (PQC) to future-proof your most sensitive assets. 6. The Failure of Static IDS Traditional Intrusion Detection Systems (IDS) rely on known indicators of compromise - assuming attackers reuse the same tools and techniques. AI‑driven attacks deliberately avoid that assumption. Threat actors are now using Large Language Models (LLMs) to weaponize newly disclosed vulnerabilities within hours. While your team waits for a "known pattern" to be updated in your system, the attacker is already using a custom, AI-generated exploit. The Risk: Your team is defending against yesterday's news while the attacker is moving at machine speed. The C-Suite Pivot: Invest in Adaptive Threat Detection. Move toward Graph‑based XDR platforms that correlate signals across email, endpoint, and cloud to automate investigation and response before the damage spreads. From Static Security to Continuous Security Closing Thought: Security Is a Journey, Not a Destination For UK enterprises, the shift toward adaptive cybersecurity is no longer optional - it is increasingly driven by regulatory expectation, board oversight, and accountability for operational resilience. Recent UK cyber resilience reforms and evolving regulatory frameworks signal a clear direction of travel: cybersecurity is now a board‑level responsibility, not a back‑office technical concern. Directors and executive leaders are expected to demonstrate effective governance, risk ownership, and preparedness for cyber disruption - particularly as AI reshapes the threat landscape. AI is not a future cybersecurity problem. It is a current force multiplier for attackers, exposing the limits of legacy enterprise security architectures faster than many organisations are willing to admit. The uncomfortable truth for boards in 2026 is that no enterprise is 100% secure. Intrusions are inevitable. Credentials will be compromised. Controls will be tested. The difference between a resilient enterprise and a vulnerable one is not the absence of incidents, but how risk is managed when they occur. In mature organisations, this means assuming breach and designing for containment: Access controls that limit blast radius Least privilege and conditional access restricting attackers to the smallest possible scope if an identity is compromised Data‑centric security using automated classification and encryption, ensuring that even when access is misused, sensitive data cannot be freely exfiltrated As a Senior Enterprise Cybersecurity Architect, I see this moment as a unique opportunity. AI adoption does not have to repeat the mistakes of earlier technology waves, where innovation moved fast and security followed years later. We now have a rare chance to embed security from day one - designing identity controls, data boundaries, automated monitoring, and governance before AI systems become business‑critical. When security is built in upfront, enterprises don’t just reduce risk - they gain the confidence to move faster and unlock AI’s value safely. Security is no longer a “department”. In the age of AI, it is a continuous business function - essential to preserving trust and maintaining operational continuity as attackers move at machine speed.

Building Secure, Enterprise Ready AI Agents with Purview SDK and Agent Framework
At Microsoft Ignite, we announced the public preview of Purview integration with the Agent Framework SDK—making it easier to build AI agents that are secure, compliant, and enterprise‑ready from day one. AI agents are quickly moving from demos to production. They reason over enterprise data, collaborate with other agents, and take real actions. As that happens, one thing becomes non‑negotiable: Governance has to be built in. That’s where Purview SDK comes in. Agentic AI Changes the Security Model Traditional apps expose risks at the UI or API layer. AI agents are different. Agents can: Process sensitive enterprise data in prompts and responses Collaborate with other agents across workflows Act autonomously on behalf of users Without built‑in controls, even a well‑designed agent can create compliance gaps. Purview SDK brings Microsoft’s enterprise data security and compliance directly into the agent runtime, so governance travels with the agent—not after it. What You Get with Purview SDK + Agent Framework This integration delivers a few key things developers and enterprises care about most: Inline Data Protection Evaluate prompts and responses against Data Loss Prevention (DLP) policies in real time. Content can be allowed or blocked automatically. Built‑In Governance Send AI interactions to Purview for audit, eDiscovery, communication compliance, and lifecycle management—without custom plumbing. Enterprise‑Ready by Design Ship agents that meet enterprise security expectations from the start, not as a follow‑up project. All of this is done natively through Agent Framework middleware, so governance feels like part of the platform—not an add‑on. How Enforcement Works (Quickly) When an agent runs: Prompts and responses flow through the Agent Framework pipeline Purview SDK evaluates content against configured policies A decision is returned: allow, redact, or block Governance signals are logged for audit and compliance This same model works for: User‑to‑agent interactions Agent‑to‑agent communication Multi‑agent workflows Try It: Add Purview SDK in Minutes Here’s a minimal Python example using Agent Framework: That’s it! From that point on: Prompts and responses are evaluated against Purview policies setup within the enterprise tenant Sensitive data can be automatically blocked Interactions are logged for governance and audit Designed for Real Agent Systems Most production AI apps aren’t single‑agent systems. Purview SDK supports: Agent‑level enforcement for fine‑grained control Workflow‑level enforcement across orchestration steps Agent‑to‑agent governance to protect data as agents collaborate This makes it a natural fit for enterprise‑scale, multi‑agent architectures. Get Started Today You can start experimenting right away: Try the Purview SDK with Agent Framework Follow the Microsoft Learn docs to configure Purview SDK with Agent Framework. Explore the GitHub samples See examples of policy‑enforced agents in Python and .NET. Secure AI, Without Slowing It Down AI agents are quickly becoming production systems—not experiments. By integrating Purview SDK directly into the Agent Framework, Microsoft is making governance a default capability, not a deployment blocker. Build intelligent agents. Protect sensitive data. Scale with confidence.Driving DevSecOps Standards: Microsoft’s Role in Shaping NIST SP 1800-44 Volume B

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

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.
