Microsoft Defender for IoT - OT Site License

Microsoft Defender for IoT helps secure operational technology (OT) networks with agentless network detection and response. The OT Site License enables broad coverage across industrial facilities, providing deep visibility into diverse IoT, OT, and ICS devices without installing software on endpoints. Defender for IoT rapidly discovers assets, maps network topologies, detects anomalies, and identifies threats using behavioral analytics and threat intelligence. It integrates natively with Microsoft 365 Defender and Microsoft Sentinel, and interoperates with external SOC tools to streamline incident investigation and response. Built for brownfield and mixed-vendor environments, it supports passive monitoring and out‑of‑band deployment to minimize operational impact while improving security posture and compliance across industrial operations.
