This article explains how Defender for IoT uses device twins and modules.

Device twins

For IoT solutions built in Azure, device twins play a key role in both device management and process automation.

Defender for IoT offers full integration with your existing IoT device management platform, enabling you to manage your device security status as well as make use of existing device control capabilities. Integration is achieved by making use of the IoT Hub twin mechanism.

Defender-IoT-micro-agent twins

Defender for IoT maintains a Defender-IoT-micro-agent twin for each device in the service. The Defender-IoT-micro-agent twin holds all the information relevant to device security for each specific device in your solution. Device security properties are maintained in a dedicated Defender-IoT-micro-agent twin for safer communication and for enabling updates and maintenance that requires fewer resources.

See Create Defender-IoT-micro-agent twin and Configure security agents to learn how to create, customize, and configure the twin. See Understand and use module twins in IoT Hub to learn more about the concept of module twins in IoT Hub.
