Show HN: Building an AI Traffic Guardrail(kilasec)

Kilasec is a network-layer guardrail for AI agents that routes only model API traffic through a self-hosted collector container plus a per-device app, requiring no SDK integration. The collector decrypts calls to apply policies (allow, mask, block, hold for a human, or cap spend), masks secrets and PII before they leave, and scans model replies for threats like reverse shells. It maps requests to users and AD groups, keeps audit history up to 7 years on paid plans, and offers a free plan for up to 5 devices.
