Measuring Agentic AI Posture: A New Metric for CISOs
In cybersecurity, we live by our metrics. We measure Mean Time to Respond (MTTR), Dwell Time, and Patch Cadence. These numbers indicate to the Board how quickly we respond when issues arise. But in the era of Agentic AI, reaction speed is no longer enough. When an AI Agent or an MCP server is compromised,…

Attackers published packages with names just close enough to popular libraries, such as “lodsash,” “expres,” “reacts,” and waited for automation or human error to do the rest. The impact was usually limited, and remediation straightforward.That model began to break in 2025.Instead…
