Microsoft – Defender XDR

Microsoft Defender XDR — presented on Microsoft's site as the Microsoft Defender Suite — unifies extended detection and response across the products in Microsoft's security portfolio, including Defender for Endpoint, Defender for Identity, Defender for Office 365 and Defender for Cloud Apps. Rather than treating each of those as a separate console, the platform correlates their signals into consolidated incidents that show an attack as it moves from a phishing message to a compromised identity to lateral movement across devices. Microsoft positions the product around turning what it calls a signal flood into clarity and action, using the scale of its telemetry to prioritize what analysts should look at first and to suppress the routine noise that dominates most alert queues. A defining capability is automatic attack disruption, which is designed to break the attack chain at machine speed by containing compromised devices or disabling implicated accounts while an intrusion is still in progress, without waiting for analyst review. The suite also surfaces exposure and posture insights so teams can close the gaps that attackers exploit before they are used, and it integrates tightly with Microsoft Sentinel for organizations that want SIEM-grade retention and custom detection engineering alongside XDR correlation.
