Applies to:

  • Microsoft 365 Defender

This article explains how to configure and monitor Microsoft Defender for Identity sensors in Microsoft 365 Defender.


As part of the convergence with Microsoft 365 Defender, some options and details have changed from their location in the Defender for Identity portal. Please read the details below to discover where to find both the familiar and new features.

View Defender for Identity sensor settings and status

  1. In Microsoft 365 Defender, go to Settings and then Identities.

    Go to Settings, then Identities

  2. Select the Sensors page, which displays all of your Defender for Identity sensors. For each sensor, you'll see its name, its domain membership, the version number, if updates should be delayed, the service status, update status, health status, the number of health issues, and when the sensor was created.

    In the Defender for Identity portal, the sensor settings and health information were in separate locations. Note that in Microsoft 365 Defender they're now on the same page.

  3. If you select Filters, you can choose which filters will be available. Then with each filter, you can choose which sensors to display.

From the Sensors page, you can add a new sensor.

    • The configuration setting file with the required information to connect to the Defender for Identity cloud service

  4. Copy the Access key. The access key is required for the Defender for Identity sensor to connect to your Defender for Identity instance. The access key is a one-time-password for sensor deployment, after which all communication is performed using certificates for authentication and TLS encryption. Use the Regenerate key button if you ever need to regenerate the new access key. It won't affect any previously deployed sensors, because it's only used for initial registration of the sensor.

  5. Copy the package to the dedicated server or domain controller onto which you're installing the Defender for Identity sensor.

Configure Directory Services account

To connect the sensor with your Active Directory domains, you'll need to configure Directory Services accounts.
