Data Redaction for GenAI

You can redact specific text when data is exfiltrated via GenAI prompt submission. Sensitive information is masked before being sent to GenAI. This feature allows you to redact content that matches the detectors selected in a rule, such as email addresses or credit card numbers.

When the user submits text containing selected sensitive information to GenAI, a notification informs them that redacted text has been submitted. The user can choose to proceed with submitting the redacted text or cancel the submission.

This feature is available from Windows 4.2.0. Contact your Proofpoint representative.
