Agent Runtime Security Crystallizes as Product Category: Microsoft Toolkit + Capsule Security + Show HN Project Ship Same Month

Microsoft Open Source Blog·high signal

Three independent agent runtime security projects shipped within two weeks: Microsoft's Agent Governance Toolkit (MIT license, 7 packages across Python/TS/Rust/Go/.NET, covers all 10 OWASP agentic AI risks at sub-0.1ms p99 latency), Capsule Security's platform with ClawGuard (funded $7M, disclosed CVEs in Copilot Studio and Agentforce), and an open-source Show HN project. The convergence marks runtime agent security as a distinct, investable category — not just a feature of existing security products.
