Platform · Audit LedgerImmutable evidence for every AI decision

Every prompt.
Every decision.
Timestamped.

The Audit Ledger is an append-only record of every event Obiguard processes — prompt, response, tool-call, policy decision, and human review action. Hand it to the auditor. Stream it to your SIEM.

01 / What is logged

Complete chain of custody.

Every record is cryptographically signed and immutable. Records cannot be edited or deleted — only appended. Retention is configurable per project.
01 — EVENTS

All AI events

Every prompt, response, and tool-call is logged — including the full content, the model called, the agent ID, and the user or service account that initiated it.

Full content · model · agent · caller
02 — DECISIONS

Policy decisions

Every policy evaluation is recorded: which Policy Set fired, which Criterion matched, what action was taken, and the timestamp to the millisecond.

Policy · criterion · action · timestamp

Human review actions

Every Review Queue action — assign, annotate, approve, escalate — is written back to the ledger with the reviewer identity and timestamp.
