Agent Governance Toolkit
Summary
Microsoft's governance layer for autonomous agents addresses all ten OWASP agentic AI risks with deterministic, sub-millisecond policy enforcement.
This is a policy engine that sits between your AI agent code and execution, enforcing security rules without requiring a rewrite of the agent itself. The problem: autonomous agents in production face ten distinct attack vectors—prompt injection, excessive agency, hallucination-driven actions, and others—that traditional application security doesn't cover. The differentiator is breadth: this toolkit addresses all ten OWASP risks in a single framework, hooks into LangChain and other agent frameworks at their extension points, and ships SDKs for TypeScript and .NET. It's free. The honest catch: it runs application-level governance in the same process as the agent, so production deployments require containerizing each agent separately rather than relying on kernel-level isolation.
Bottom line: *Use this if you're running agents in regulated industries or multi-tenant systems where compliance and containment matter more than simplicity.*

Pros
Sign in to edit- First toolkit to address all 10 OWASP agentic AI risks with deterministic, sub-millisecond policy enforcement
- Framework-agnostic from day one, hooks into framework native extension points so adding governance does not require rewriting agent code
- Available across language ecosystems with TypeScript SDK through npm and .NET SDK through NuGet
- Structured as monorepo with independently installable packages allowing incremental adoption
- Ships with 9,500+ tests and includes SLSA-compatible provenance, OpenSSF Scorecard tracking, CodeQL scanning, and Dependabot dependency monitoring
Cons
Sign in to edit- Provides application-level governance, not OS kernel-level isolation; policy engine and agents run in same process, so production recommendation is to run each agent in separate container
- Toolkit is currently in public preview and may have breaking changes before GA
- Real-world production adoption evidence still limited (announced April 2026)
