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

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

The Impact

Security teams and data owners are affected by improved data classification and control, reducing the risk of data leakage.

• Security Teams: Enhanced data classification reduces risk of sensitive data exposure.
• Data Owners: Simplified labeling ensures consistent application of data protection policies.
• Compliance Officers: Better data governance supports regulatory compliance and auditing.
• Copilot Users: Output artifacts inherit sensitivity labels, preventing accidental oversharing.

The Action

1. Review existing Purview sensitivity labels for suitability with document library defaults.
2. Communicate new labeling capabilities to SharePoint site owners and data stewards.
3. Develop or update internal guidelines for applying default sensitivity labels to SharePoint document libraries.
4. Monitor Purview activity logs for label application and compliance.
