What it checks
Data Loss Prevention policies for Power Platform control which connectors can be used together within Power Apps and Power Automate flows, preventing unauthorized data movement between business and non-business data sources. Without DLP policies, users can create flows that automatically transfer corporate data from SharePoint, Dynamics 365, or Azure SQL to personal email, social media, or third-party cloud storage. DLP connector classification is the primary mechanism for preventing data exfiltration through citizen-developed applications.
Recommended value
Tenant-level DLP policy classifying business-critical connectors (SharePoint, Outlook, Dataverse) as Business and blocking their combination with non-business connectors; environment-level policies for specific use cases
Remediation
Create a tenant-level DLP policy that classifies all connectors containing corporate data (such as SharePoint, Outlook, Dataverse, Azure SQL, and OneDrive) in the Business group and moves known non-business connectors to the Blocked group. Review the default connector classification to ensure that newly released connectors are automatically placed in the Non-Business group until reviewed and approved. Create environment-specific DLP policies for environments that require access to additional connectors beyond the tenant-level policy, ensuring they are at least as restrictive as the tenant policy.
Fixture-proven verdicts
Every verdict below is proven by a golden fixture in the module's gating test suite. This table derives from the last green run; it cannot be edited by hand.
| Scenario | Expected verdict |
|---|---|
| clean | PASS |
| known-bad | FAIL |
| throttled | Not Assessed |
