Minor update or fixes

This release improves existing features:

Spreadsheet cell delimiter for macOS - The Respect Cell Boundaries in Spreadsheets checkbox in Content Tracking → Text Extractor prevents the incorrect identification of random 16-digit numbers. By default, this checkbox remains unchecked.

This feature addresses issues with false positive matches during regex testing for sensitive data. It allows users to configure the delimiter between cell values by checking the Respect Cell Boundaries in Spreadsheets checkbox, preventing unintended regex matches. As a result, data accuracy improves, and false positives are significantly reduced.

New built-in custom validators - Trellix Data Loss Prevention has introduced 13 built-in custom validators to accurately validate Personally Identifiable Information (PII) and Financial Account Information. These validators are designed to streamline data validation processes, ensuring compliance with regional regulatory standards and improving the accuracy of sensitive data identification.

The newly added validators include:

  1. Argentina CUIT

  2. Indonesia ID

  3. Japan National ID

  4. Malaysia ID

  5. Mexico Bank Account Numbers

  6. Mexico SSN

  7. Turkish ID

  8. UAE ID

See Classification Definitions Reference Guide for detailed information on the regex patterns used for these validators.

This update resolves the following issues.

Note
