Defender for Identity Sensor Health
The question it answers: Are the Defender for Identity sensors running, and which health issues are open?
Defender for Identity watches domain controllers for Kerberoasting, DCSync, pass-the-hash and similar attacks - but only while its sensors run, its directory service account works and auditing is configured. Open health issues mean attacks on Active Directory may go undetected.
