Evidence & Audit

Logs show activity.
Evidence proves control.

Every AI security decision becomes a tamper-evident, hash-chained record — mapped to your compliance frameworks and verifiable by an auditor independently, with zero trust in Purogaly required.

What every record contains

A complete account of every AI decision.

Not just that something happened — who, what, why, and what was done about it, in a form that holds up to independent scrutiny.

Who or what acted

The user, service, or agent — and on whose behalf

Which AI was involved

The AI app, model, or endpoint in the interaction

What policy applied

The policy that matched and the risk detected

What action was taken

Allowed, masked, blocked, escalated, or approved

Tamper-evident by design

Hash-chained, and verifiable offline

Each record is cryptographically linked to the one before it, so the sequence can't be altered after the fact. Anyone can verify the chain independently — no trust in Purogaly required.

  • Every record chained to the previous one
  • Any change to history breaks the chain
  • Independent, offline verification

Audit reports

From raw activity to an audit package

Generate evidence reports scoped to a framework and time period — the documented, verifiable trail an auditor or regulator expects, produced from real activity rather than assembled by hand.

  • Reports scoped by framework and date range
  • Control mapping built in
  • Backed by the verifiable evidence chain
