What it checks
All users and applications should be covered by at least one Conditional Access policy. Gaps in coverage leave users or applications without security controls such as MFA, device compliance, or location restrictions, creating attack vectors for unauthorized access.
Recommended value
100% of active users and critical applications covered by at least one CA policy
Remediation
Review all Conditional Access policies to identify users and applications that are not targeted by any policy. Create policies that cover uncovered users and applications with appropriate grant and session controls. Prioritize coverage for privileged accounts and business-critical applications.
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 |
