Patch and move on? Why vulnerability response doesn't end there

Fresh off the PHP2Shell advisory, former DHS CISO and acting deputy CIO Hemant Baidwan — now executive CISO at Knox Systems, the largest federal managed cloud — joins Safe Mode to break down what actually happens in the hours after a high-severity vulnerability drops. He walks through why "patch it and move on" gives teams a false sense of security, how to map internet reachability in environments that change by the hour, and what a CISA KEV listing really signals to defenders. Baidwan also reflects on writing DHS's first-ever AI cybersecurity guidance, what he'd add to that playbook today — starting with AI agent identity — and why he thinks compliance has drifted into security theater.
