What it checks
Full disk encryption ensures that data stored on device drives is protected if the physical device is lost, stolen, or decommissioned. Devices without encryption enabled expose corporate data including cached credentials, documents, and email to physical theft attacks. Monitoring encryption status across the fleet identifies devices that have failed encryption or have not yet been encrypted.
Recommended value
100% of managed devices reporting encryption enabled on all drives
Remediation
Review the Intune encryption report to identify all devices that are not reporting full disk encryption as enabled. Investigate encryption failures which may be caused by unsupported hardware, TPM issues, or policy conflicts and resolve the underlying causes. For devices that cannot support encryption, evaluate whether they should be allowed to access corporate resources and consider blocking them through Conditional Access policies.
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 |
