Microsoft launches integrated security operations center preview in Defender
Microsoft announced the Integrated Security Operations Center (ISOC) as a preview feature of Microsoft Defender. ISOC combines security information and event management (SIEM) with threat protection into a single platform, giving both human analysts and autonomous agents a shared foundation of signals, context, and actuators.

Key points
- ISOC merges SIEM and threat protection in Microsoft Defender, now available in preview.
- Unified signals, context, and actuators let agents and humans act together at machine speed.
- Reduces manual tool stitching, enabling analysts to focus on judgment and outcomes.

ISOC extends that stack by unifying the detection, prediction, and response loop, allowing continuous pre‑breach protection and real‑time threat adaptation. Practitioners can focus more on decision‑making rather than manual integration, and the system can evolve as new capabilities are added. The preview is available now, with a recording of the launch and a whitepaper provided for deeper details.
