Microsoft Purview Information Protection: Doc library default labeling for SharePoint Online and Copilot

🚨 The Signal: SharePoint document libraries can now automatically apply Purview sensitivity labels to unprotected files. This enhances data classification, improves DLP, and ensures Copilot output inherits sensitivity, strengthening data protection and governance.

The Impact

SharePoint admins and security teams are affected, with a reduced risk of unclassified sensitive data exposure and improved Copilot data handling.

• SharePoint Admins: Reduced manual labeling effort, improved data consistency.
• Security Teams: Enhanced data visibility, better DLP enforcement.
• Copilot Users: Output artifacts inherit sensitivity, reducing data leakage risk.
• Data Owners: Simplified classification, better control over sensitive information.

The Action

1. Review existing Purview sensitivity labels for suitability with document library defaults.
2. Identify SharePoint document libraries containing sensitive data requiring default labeling.
3. Educate SharePoint site owners on the new default labeling capability and its benefits.
4. Configure default sensitivity labels on relevant SharePoint Online document libraries via the SharePoint admin center or Purview compliance portal.
5. Monitor label application and DLP alerts to ensure proper classification and enforcement.
