The Microsoft Agent Governance Toolkit is an open-source runtime security and policy enforcement framework for autonomous AI agents. It covers all 10 risks in the OWASP Agentic AI Top 10 — from prompt injection and excessive agency to memory poisoning and supply chain vulnerabilities. The toolkit provides sub-millisecond policy hooks that integrate with LangChain, CrewAI, Google ADK, and most other major agent frameworks, across Python, Rust, TypeScript, Go, and .NET. The core approach is "policy as guardrail": rather than trying to make agents safe by constraining their prompts, the toolkit enforces runtime boundaries on what agents can actually do — file access, API calls, tool invocations — before execution happens. Think of it as a capability firewall for agents, similar to how AppArmor works for Linux processes. As enterprises push AI agents into production, governance and compliance are becoming blockers. The toolkit was designed in collaboration with Microsoft's security research teams who've been auditing internal agentic deployments. It ships with a policy library covering common enterprise scenarios (PII access, external API calls, sensitive file paths) and a dashboard for audit logging — addressing the 'how do I explain what my agents did' problem that's stalling adoption in regulated industries.

Mozilla's AI security team — 0DIN (Zero Day Investigation Network) — open-sourced their internal LLM vulnerability scanner on April 10, 2026. Unlike synthetic red-teaming tools, this is built on real attack knowledge: 0DIN researchers have spent two years getting paid to break every major frontier model, discovering and reporting thousands of verified vulnerabilities. Those discoveries are now encoded as reproducible probes. Built on NVIDIA's GARAK open-source framework, the 0DIN Scanner adds a graphical interface, automated scan scheduling, cross-model comparative analysis, and enterprise reporting. It ships with 179 community probes covering 35 vulnerability families — prompt injection, jailbreaks, data leakage, harmful content generation, and more — all aligned to the OWASP LLM Top 10. Six specialty probes target advanced threat categories. For any team deploying LLMs in production — RAG systems, agents with tool access, customer-facing chatbots — this is now the baseline for security auditing. The Apache 2.0 license means enterprise deployment without legal headaches. With LLM security audits running $50K-$200K from specialist firms, this democratizes access to professional-grade testing.
Reviewer scorecard
“Finally, something that treats agent security as a runtime enforcement problem rather than a prompting problem. The multi-language, multi-framework support is essential — real enterprise deployments aren't all Python. Sub-millisecond overhead means you can actually use this in production without performance concerns.”
“Every team shipping LLM features in production should be running this in CI. The OWASP LLM Top 10 alignment means it maps directly to compliance frameworks. The fact that it's built from actual vulnerabilities found in frontier models — not synthetic prompts — gives it way more credibility than competitors.”
“Microsoft releasing an 'agent governance' toolkit while simultaneously deploying agents at scale internally is a bit self-serving. The OWASP list it covers is brand new and largely unvalidated against real attacks. Policy enforcement frameworks also have a history of generating compliance theater rather than actual security.”
“GARAK-based scanners catch known vulnerability patterns, but novel attacks will always slip through static probe libraries. The graphical interface is serviceable but not polished enough for non-technical security teams. And 179 probes sounds like a lot until you realize a dedicated red teamer generates thousands of custom vectors in a day.”
“This is infrastructure for the agent economy. Just as WAFs became table stakes for web applications, runtime governance toolkits will become standard issue for agent deployments. The OWASP framing gives the security community a shared vocabulary, which accelerates standardization.”
“As LLM agents gain tool access and real-world power, security becomes existential not optional. Mozilla's decision to open-source two years of hard-won attack knowledge is a rare act of public benefit in a space dominated by consulting firms charging enterprise rates. This becomes the industry standard within 12 months.”
“For creators using AI agents to manage content pipelines, the PII access controls and audit logging are genuinely useful. Knowing that your agent can't accidentally exfiltrate subscriber data to an external API is peace of mind, not just compliance theater.”
“Even content teams using AI for copywriting or customer service need to know their models won't be jailbroken into producing harmful outputs. This gives non-technical managers a report they can actually present to legal. That's underrated value.”
