AI agent audit trail

Cryptographic audit trail and provenance for AI agents

An AI agent audit trail records what each agent did, why, and on whose authority — in a form no one can quietly edit later. Aarvion signs every consequential action against your governance and hash-chains it, so your audit is a mathematical proof, not a best-effort log.

From 14-day reconstruction to 90-second query

Reconstructing what an AI agent did across logs, tickets, and approvals can take weeks. Aarvion replaces that with a single query: filter by agent and time window, and get a signed PDF in about 90 seconds.

Each record links to a human, an approval, a rule version, and a manifest commit — so the story of every decision is already assembled.

Tamper-evident by construction

Every record is signed and externally witnessed, and the chain is hash-linked. Tamper with any field and the chain breaks, mathematically — there's no silent edit.

  • Manifest version history, signed commit by commit
  • Provenance chain across thousands of records, hash-linked
  • External witness proofs with trusted timestamps
  • Held decisions captured with their human approver

An audit your business, engineers, and regulator all trust

Because provenance is captured at the moment of the action — not reconstructed afterwards — the same trail satisfies an internal incident review, an engineering postmortem, and an external regulator query without extra work.

Frequently asked

AI agent governance, answered.

What makes the audit trail tamper-evident?
Records are signed, hash-chained, and externally witnessed. Changing any field breaks the cryptographic chain, so tampering is detectable rather than hidden.
What's in the audit output?
A signed PDF containing the manifest version history, the hash-linked provenance chain, external witness proofs, and held decisions with their human approvers.
