What Are SIEM & XDR
Security Information and Event Management (SIEM) centralises log data from across your IT environment, enabling real-time threat detection and compliance reporting.
Extended Detection and Response (XDR) integrates protection across endpoints, identities, email, and cloud workloads, correlating signals to stop advanced attacks faster.
Microsoft leads the way with:
- Microsoft Sentinel: A cloud-native SIEM delivering AI-driven analytics and automation.
- Microsoft Defender XDR: A unified platform for cross-domain threat detection and response.
Together, they enable organisations to move from reactive security to proactive defence.
