The adversary was clear. The surface was known. The playbook, while imperfect, was at least legible, but that story is now changing.

The next major frontier in cybersecurity is not defending against AI. It is figuring out how to trust it.

The Agent Is Already In the Building

Autonomous AI agents are being deployed today reading inboxes, executing code, transferring funds, signing off on contracts, and making decisions that in any previous era would have required a human signature. The agentic economy is not on the horizon. It is already operating inside your perimeter.

The speed of adoption is understandable, and the productivity case is compelling. A single AI agent can compress weeks of analyst work into ...
