agent's audit evidence had PII in screenshots: redaction pass

TL;DR

The evidence screenshots captured PII (names, emails, IDs) alongside the proof, creating a privacy incident inside a compliance artifact. Add a redaction pass: blur or mask PII regions before the screenshots enter the evidence store. Evidence must prove the control, not expose the data.

agent's audit evidence had PII in screenshots

Steps

1. Inventory the affected screenshots and the PII types visible. Expected: The exposure is mapped.

2. Redact the stored copies: blur or mask the PII regions. Expected: The evidence is clean.

3. Restrict access to the unredacted originals until they are replaced or purged. Expected: The exposure is contained.

4. Add the redaction pass to the evidence pipeline: every screenshot gets reviewed or auto-redacted before storage. Expected: Future evidence is clean by default.

5. Check the retention: purged originals must actually be purged, including backups. Expected: The PII is gone, not just hidden.

When to use

• evidence screenshots contain PII
• screenshots are captured automatically
• the evidence store is broadly shared

When not to use

• the PII is the evidence (then get explicit authorization and restrict access)
• screenshots are already redacted (verify the redaction quality)
• no screenshots are taken (nothing to redact)

Tool compatibility

• any evidence collection
• screenshot redaction

Variant phrasings

• "audit evidence PII screenshots"
• "redact PII evidence screenshots"
• "screenshots contain personal data audit"

Why it happens

Evidence screenshots are taken to prove a control, and the screen often shows more than the control: user lists, emails, personal data. The evidence store then becomes a PII store with compliance-grade retention. Redaction at capture keeps the proof while removing the personal data.

Edge cases

• auto-redaction needs verification; it misses novel PII layouts
• the purge must cover backups, or the PII survives the cleanup
• the authorization for PII-as-evidence must be explicit and documented
