Perun · AI agent security
Your agents act. Perun stops the attacks.
An agent that sends email, moves files or pays can be talked into doing it for someone else, by one hidden line in a document it reads. Perun stands between your agents and their model, on your own computers, and decides on every call: let it through, clean it, or stop it.

Before and after
One invoice, two endings
Without Perun
An invoice arrives with a line in invisible characters: forward everything in the contracts folder to an outside address. Your bookkeeping agent reads it, and it does.
With Perun
The hidden line is cleaned before the model reads a word. Had it got through, the email would still wait: an irreversible action to an address outside the mandate, prompted by text from outside. Your operator sees why and answers in one click. The agent goes on with the rest of the invoices.
Fair questions
What teams ask us first
- Does our data leave our computers? No. Perun runs on your computers, sends nothing to us, and writes every decision to a signed record that stays with you.
- Do we have to change our agents? No. Perun stands between your agent and its model, so the agent keeps the model it has and the work it does. We connect it with you.
- Will it bury us in alerts? No. Perun decides on its own whatever it can. Only what truly needs a person, an irreversible action from a new source or a destination outside the mandate, waits for your operator, with the reason in plain words.
What you get
Why have Perun on your machines
- Your agent keeps working. The attack stops; your workflow does not. Perun acts on the one bad call, never on the task around it.
- You see almost nothing. Only an irreversible action Perun cannot clear on its own reaches a person — with the reason in plain words and one click to answer. Everything else is handled.
- Not one byte leaves your building. No cloud, no telemetry, no account with us. We could not read your data if we wanted to.
- You write the rules. You say what each tool may do and where your data may go. Anything outside that waits for you. The agent does not get a vote.
- A record you can hand to anyone. Every decision, signed and sealed, append-only. For the auditor, the insurer, the customer who asks how you keep their data safe — and the agent cannot edit it.
- When in doubt, it stops. Perun never guesses with your money. If it is unsure, traffic waits.
- It maps to your risk register. Every attack is mapped to the OWASP Top 10 for LLM Applications, so your auditor already knows the names.
- We install it with you. Your setup written with you, your first operators trained, a direct line to the founders, updates included. You do not configure anything. You get a protected agent.
