Immutable Audit Trail
A tamper-proof log of every access event in a data room, stored in an append-only database table.
An immutable audit trail is a chronological record of every event in a data room — access attempts, document views, downloads, OTP requests, blocked forwards — that cannot be modified or deleted after it is written. PrimeVDR implements this as an append-only Postgres table where UPDATE and DELETE are revoked at the database role level. The audit trail serves two purposes: security (identifying who accessed what and when) and legal (providing an evidence record in the event of a data leak or dispute). Entries include: event type, recipient email hash, IP address hash, document ID, timestamp, and session ID.
Example
After a financial model appeared on a competitor's website, the founder pulled the audit trail and identified the recipient whose session preceded the leak — the only person who had both accessed and downloaded that specific document.
