An executive-level introduction to agentic security and governance, designed to help CISOs understand emerging AI agent risks and prepare for adoption.

Across conversations with CISOs in 2025, a clear need has emerged for a grounded understanding of AI agents and what they mean for enterprise security. Many leaders are already seeing early examples of agentic behaviour across their organisations, yet the language and frameworks available today often fall short of describing how these systems think, decide, and act.

The guide offers a structured approach for moving from early experimentation toward steady and confident adoption, helping leaders develop a shared vocabulary and a thoughtful plan for readiness.

Included:

  • A clean, usable understanding of what an AI agent is across your organisation, grounded in practical examples, including agents you might not realize are already live in your environment.
  • Predetermined logic vs. decision-making, and why agents are harder to audit, bound, and predict than traditional automation.
  • Levels of autonomy, and how autonomy changes control requirements.
  • The agentic threat landscape, including silent failures, cascading errors, and how familiar risks get amplified at agent scale.
  • A phased adoption and transition playbook, highlighting the three agentic governance priorities CISOs must get right.
