+|Column name |Description  |
+|---------|---------|
+|Sensor name| Displays the name that you assigned to the sensor during the registration. |
+|Sensor type| Displays whether the sensor is locally connected or cloud-connected. |
+|Zone| Displays the zone that contains this sensor.|
+|Subscription name| Displays the name of your Microsoft Azure account subscription. |
+|Sensor version| Displays the software version installed on your sensor. |
+|Sensor status| Displays a [sensor health message](sensor-health-messages.md). For more information, see [Understand sensor health (Public preview)](how-to-manage-sensors-on-the-cloud.md#understand-sensor-health-public-preview).|
+|Last connected (UTC)| Displays how long ago the sensor was last connected.|
+|Threat Intelligence version| Displays the Threat Intelligence version installed on the sensor. The name of the version is based on the day the package was built by Defender for IoT. |
