Verify a proof. Trust nobody.

Drop a proof bundle, certificate, agent record, observed-dependency evidence, or a NIS2 posture freeze. It re-verifies here in your browser — nothing uploads, no login. The same recomputation an auditor runs, with zero access to our systems. Trust the proof without trusting us.

What re-runs on your machine
  • (01)Hash chainEvery record links to the previous one — recompute the digests and the chain either holds or breaks.
  • (02)Ed25519 signatureThe bundle is signed. We re-check the signature against the published key, in your browser.
  • (03)Witness re-checkFor a certificate, re-run the traversal over the shipped graph and confirm the crown is outside the reachable set.
  • (04)Freeze consistencyFor a NIS2 posture freeze, re-check the signature and every internal-consistency rule. Dates are evaluated in UTC.

Drop a proof. Watch it re-check.

Everything runs client-side — the file never leaves your machine. This is the same recomputation an auditor performs, with zero access to our systems.

Prefer the command line, or want to verify offline with no browser? The same verifier also runs as a zero-dependency CLI for fully offline re-checks. Export your bundle from Audit readiness → Offline-verifiable proof bundle.
