Sensitivity Label Coverage Lens
The Sensitivity Label Coverage Lens shows how completely and consistently Microsoft Purview sensitivity labels are applied across SharePoint, OneDrive, Teams, and Exchange. Leaders can identify unlabeled, inconsistently labeled, or potentially exposed content and prioritize where classification effort will deliver the greatest reduction in AI and governance risk.

- Percentage of content labeled versus unlabeled by workload
- Sites, libraries, and mailboxes with the largest classification gaps

- Sensitive content that appears to be under-classified
- Areas where labeling debt is growing over time
Signals It Brings Together
- Microsoft Purview sensitivity label configuration and application
