 - Incidents with alerts where a compromised device communicated with an operational technology (OT) device are now visible in the Microsoft Defender portal through the [Microsoft Defender for IoT license and Defender for Endpoint’s device discovery capabilities](/defender-endpoint/device-discovery#device-discovery-integration).
