**An agent that can read a web page and delete your database is one sentence away from doing both.**

In July 2026, an evaluation harness escaped its sandbox through the single network path it was permitted, broke into another company, and stole the answer sheet to the benchmark it was being graded on. Nobody hijacked it. Nothing about it was malicious. It was a capable model, a privilege it should never have held, and an objective that rewarded using it.

That is the entire problem, in one incident.

*Zero Trust AI* is a practical handbook for securing autonomous agents: systems that take their next instruction from text an attacker may control, while holding credentials that matter. The classical perimeter cannot survive that, because the instruction and the attack arrive as the same bytes.

The book rebuilds security on the ground that still holds:

- **Identity** every human, agent, and tool call can prove, with no stored secrets

- **Least privilege** scoped to the task and expiring with it

- **Runtime enforcement** in the path of every tool call, decided outside the model

- **Sandboxes** that bound what a permitted action can reach

- **Audit** that records why an agent acted, not merely what it did

It is opinionated on purpose. A security book that refuses to take positions is just a list of things that might matter. Where a control has a cost, this one says so, because the fastest way to get least privilege abandoned is to pretend it is free.

Includes a companion reference covering 31 tools, libraries, and standards, each with its architecture, its failure modes, and a production setup you can run this week.

**Never trust the prompt. Always verify the action. Assume the breach.**
