Defend your company from loss, harm and rogue AI, from the inside out.

Promethyn is zero trust for AI agents. Agents never hold your keys, every action is proven safe before it becomes real, and an agent that turns hostile is cut off and contained before it can spread.

How it works, on every change

Choose how your agents run

Two ways to let AI agents into production.

With one of them, you find out what happened afterwards.

The blue pill

Trust the agent. Hope it holds.

Agents carry your keys and credentials.
You approve a diff and hope it runs the way it read.
Logs explain the damage after it is done.
A rogue agent keeps going until someone notices.
The record sits where the agent can reach it.

The red pill

See it before it is real.

Agents hold no keys. Promethyn acts for them.
Every consequential change is shown safe before it becomes real.
Approvals are signed, single-use and bound to that exact change.
A hostile agent is stopped and sealed off. (containment in preview)
Every decision leaves evidence anyone can verify offline.

Pick one.
