PROOFstamp is the certification mark issued by PESA to agentic AI runtime security products that pass a live adversarial benchmark run administered by an independent test lab. No self-attestation. No questionnaire. A real test.
A PROOFstamp does not say a product was tested. It says the product is passing.
Every certified build carries an expiry. The mark lapses on that date unless a subsequent run has executed and published. Execution stops, the assertion stops. There is no grace period, no provisional status, and no version of the mark that means "recently."
This is not a restriction on the mark. It is the mark. A certification that does not expire when the threat landscape moves has measured a moment and sold it as a state.
If you're building agentic AI security tooling, run your product against the Gauntlet. PROOFstamp is the only credential in this space backed by a public, tamper-evident benchmark record — not a questionnaire.
