Microsoft Defender for IoT provides agentless network monitoring for enterprise IoT devices and industrial operational technology environments using embedded sensors and dedicated appliances to passively collect data without disrupting operations. It offers real-time asset discovery with device context, risk-based vulnerability management, and threat detection powered by behavioral analytics, machine learning, and OT-specific threat intelligence from Microsoft's Section 52 research team. The solution integrates with Microsoft Defender XDR and Microsoft Sentinel for unified security operations, enabling alerts, incident correlation across IT/OT boundaries, and advanced hunting queries. It supports both cloud-connected and on-premises sensor deployments and can scale for large distributed environments.
