The Agent Control Plane: Why Enterprise AI Needs Identity, Gateways, Policy, and Observability Before More Prompts

This article argues that as enterprise AI agents evolve from simple chat interfaces to systems that can read data, call APIs, and trigger workflows, relying solely on prompts for security is insufficient. It introduces the concept of an 'agent control plane'—including identity management, tool access policies, enforcement, auditability, and observability—as the new boundary for safety. The piece references Google, Microsoft, and AWS approaches to agent governance and contrasts prompts (behavioral guidance) with control planes (operational enforcement), emphasizing the need for attribution, permissions, and rollback capabilities in production environments.
