Had an embarrassing incident where our content generation workflow leaked real customer emails into draft marketing copy. Currently using regex patterns to mask data, but new field types keep slipping through. What’s your go-to method for bulletproof data hiding in complex automations?
Latenode’s document processing templates auto-mask 15+ PII types out of the box. Set it once in the workflow and it applies to all agents. Saved us from GDPR headaches last quarter.
Implement context-aware masking - train a small model to recognize sensitive patterns beyond just regex. Combine with deterministic rules for known fields. We use a two-layer approach that catches 98% of leaks without manual review.
field-specific masking rules + random sampling checks works okay for us. not perfect but catches most issues
