Show HN: Runtime Security for AI Agents — Open-Source Protection Against Injection, Tool Abuse, and Data Exfiltration

Show HN·medium signal

A new Show HN project addresses runtime security challenges for LLM systems in production, providing open-source protection against prompt injection, tool abuse, and data exfiltration. Arrives the same week as Capsule Security's $7M launch and Microsoft's Agent Governance Toolkit, signaling that agent runtime security is crystallizing as a distinct product category. The convergence of three independent security projects in the same week suggests enterprise AI agent adoption is hitting the governance threshold.
