Microsoft Releases Agent Governance Toolkit: First Open-Source Framework Covering All 10 OWASP Agentic AI Risks

Microsoft Open Source Blog·high signal

Microsoft open-sourced the Agent Governance Toolkit under MIT license on April 2, a seven-package system (Python, TypeScript, Rust, Go, .NET) that provides sub-millisecond deterministic policy enforcement against all 10 OWASP Agentic Top 10 risks including goal hijacking, tool misuse, memory poisoning, and rogue agents. The toolkit includes Agent OS (policy engine intercepting every agent action), Agent Mesh (agent-to-agent communication security), Agent Runtime (dynamic execution rings), and Agent SRE (reliability engineering). This is the first toolkit to address the full OWASP agentic taxonomy with deterministic enforcement rather than heuristic detection.
