TL;DR

Traditional API security fails with AI agents because non-deterministic agents autonomously select tools, query databases, and execute multi-step plans across enterprise systems.

Production agent governance requires an infrastructure control plane that decouples policy enforcement from application code using scoped virtual keys, granular tool filtering, and runtime guardrails.

Bifrost adds only 11 microseconds of latency overhead at 5,000 requests per second while enforcing spend limits, content safety, and provider routing across more than 1,000 models.

Model Context Protocol (MCP) governance restricts which tools, APIs, and file systems an agent can invoke, preventing prompt injection attacks from triggering unauthorized operations.
