Microsoft introduces a new approach to security operations built for AI agents

What happened
Microsoft News says it is announcing ISOC in Microsoft Defender : a foundation built for agentic security that brings leading solutions for security information and event management (SIEM) and threat protection together.

What once required entire teams now requires a single operator and an agent framework. That shift has exposed a hard truth: security cannot operate at AI speed when protection and operations are built as separate systems.
They need signals and sensors that provide visibility, context that turns those signals into understanding, and actuators that translate decisions into protection. With ISOC, these layers work in unison, so agents can move beyond isolated tasks and help operate an agentic SOC.
