If you're a CISO, you're probably in this situation: your CEO wants AI agents everywhere, your engineering team deploys them faster than you can audit them, and you need to guarantee the security of everything.
The problem
AI agents aren't traditional applications. They make autonomous decisions, access sensitive data, evolve over time, and interact with critical systems.
The 5 essential controls
1. E2E encryption of agent communications. Not TLS. E2E. The server must never see plaintext content.
2. Immutable audit trail. Every agent decision must be immutably logged.
3. Granular control policies. Define what each agent can and cannot do.
4. Operational Kill Switch. Stop any agent in under 30 seconds. Test it regularly.
5. Per-agent data isolation. Each agent should only access data strictly necessary for its mission.
The recommended posture
Don't block AI. Govern it. The CISO who says "no" to AI gets replaced. The CISO who says "yes, with these controls" is indispensable.
