Overview
Microsoft Defender is a family of security products managed through Microsoft security portals. Its portfolio includes Defender for Endpoint, Defender for Office 365, Defender for Identity, Defender for Cloud Apps, Defender for Cloud, and Microsoft Defender XDR.
Defender XDR correlates alerts and security signals from supported Microsoft security services into incidents. Security teams can investigate incidents, perform threat hunting, configure custom detections, and automate response actions.
The product family targets organizations that want integrated protection across devices, identities, email, collaboration services, SaaS applications, and cloud infrastructure. Licensing depends on the specific Defender workload and Microsoft subscription.
