FAQ
Frequently asked questions.
Can I customize detection?
Yes. Admins can configure PII categories and strictness levels per user group.
What happens to detected data?
Detected PII is masked or blocked depending on configuration. Detected values are replaced with placeholders before the AI call; the masked request is sent to the model.
Does it work with uploads too?
Yes. Documents are analyzed before processing. Admins control allowed file types per group.
