What Defender XDR does
Defender XDR integrates Microsoft Defender for Endpoint, Microsoft Defender for Identity, Microsoft Defender for Office 365, and Microsoft Defender for Cloud Apps. This unification correlates security events across all four domains, folding seemingly disparate incidents into a single, actionable alert. Advanced hunting, written in Kusto Query Language (KQL), lets security teams search proactively for threats and uncover hidden attack patterns. Automated attack disruption features help to quickly contain and remediate threats.
Defender XDR in the AU SOC
AU mid-market Security Operations Centres (SOCs) using Defender XDR typically observe a significant increase in alert volume compared to relying on individual Microsoft Defender components. Many organisations pair Defender XDR with Microsoft Sentinel for long-term data retention and to broaden the scope of security signals beyond Microsoft’s native services. Microsoft Defender Experts for Business provides a managed extension of the SOC, offering access to Microsoft’s threat intelligence and incident response expertise. Alignment with the ACSC Essential Eight is facilitated through improved visibility and automated response capabilities, contributing to a stronger security posture.
