As enterprises move from experimenting with AI to deploying autonomous agents in real environments, the central issue for security leaders is no longer novelty but control: product and AI teams may see capability and efficiency, but CISOs see a new class of privileged, fast-moving attack surface that must be tested, constrained, and governed before it is trusted. The anecdote of a CISO immediately “hacking” a newly introduced agent captures the right instinct. Agentic systems should be treated less like polished innovation and more like potentially unpredictable operators with access, permissions, and the capacity to fail at scale. For CISOs, the message is blunt: AI agents do not become enterprise-ready because they demo well. They become enterprise-ready only when they survive adversarial scrutiny, operate within clear trust boundaries, and prove they can support business value without quietly expanding risk.
