PII Masking

PII (Personally Identifiable Information) masking automatically redacts sensitive data from your content to protect privacy and comply with data protection regulations.

​
How PII Masking Works

PII masking operates across three key areas:

  • Questions asked: User queries are scanned and sensitive data is masked before processing
  • File attachments: Documents uploaded during question asking are processed for PII removal
  • Data source indexing: All data sources are masked during the indexing process

When a regex pattern matches content, it’s replaced with <<label>> format (e.g., <<EMAIL>>, <<SSN>>).

​
Configuration

Configure PII masks using regex patterns:

  • Case sensitive: All pattern matching is case-sensitive
  • PCRE 2 standard: Follows Perl Compatible Regular Expressions 2 specification
  • Validation: Test your regex patterns at regex101.com before implementation

​
Example Results

The masking process automatically identifies and replaces sensitive information while preserving the overall context and readability of your content.
