Measuring Agentic AI Posture: A New Metric for CISOs

This article proposes “Agentic AI Posture” as a proactive framework for securing AI agents and MCP servers, arguing traditional metrics like MTTR and patch cadence are insufficient for AI-driven, API-centric environments. It recommends tracking three pillars—Visibility Ratio (shadow vs. known agents), API privilege density (functional over-permissiveness), and Behavioral Integrity (anomalies vs. baseline)—to quantify risk and guide governance. The post highlights how Salt Security maps AI agent/API activity, identifies shadow agents, and calculates risk scores to prioritize high-risk assets, enabling CISOs to communicate API risk factors and maturity to boards.
