Evidence that demonstrates this control

Examples of records an assessor would expect to see. Until a named reviewer has examined them, evidence is labelled User-asserted or Missing evidence in VERITRAIL outputs, never Verified.

Indicative framework mappings

Framework mappings are indicative VERITRAIL interpretations to support governance readiness and evidence collection. They do not constitute legal advice, a certification, or a determination of conformity with ISO/IEC 42001 or compliance with the EU AI Act or any other law.

Where the self-assessment asks about it

  • DAT-Q3 — Are sensitive data fields redacted, masked, or excluded from prompts, logs, and external model calls?

Related critical risk flags

  • Sensitive data may reach prompts, logs or external models — Unredacted personal or confidential data in prompts and logs creates privacy and confidentiality exposure.
