A Prompt Isn't
A Policy.

Telling an agent to “be careful” is not a safeguard. A prompt can be ignored, drift over time, or be talked around.

Acira enforces policy at the browser control layer, where agents send commands and receive browser output. It uses CDP today and is built to support other control points, so actions can be secured before they run.

Frequently Asked
Questions

Acira is a security layer that sits between your AI agent and the browser. Instead of asking the model to behave, it intercepts every command at the Chrome DevTools Protocol level and enforces your policy deterministically -- allow, redact, substitute, or block -- before anything executes. The model never holds your secrets and can't talk its way past the guard.
