Manage your OT device inventory from an on-premises management console

Use the Device inventory page from an on-premises management console to manage all OT and IT devices detected by sensors connected to that console. Identify new devices detected, devices that might need troubleshooting, and more.

For more information, see What is a Defender for IoT committed device?

Tip

Alternately, view your device inventory from a the Azure portal, or from an OT sensor console.

View the device inventory

To view detected devices in the Device Inventory page in an on-premises management console, sign-in to your on-premises management console, and then select Device Inventory.

For example:

Screenshot of the on-premises management console Device Inventory page.

Use any of the following options to modify or filter the devices shown:

Option Steps
Sort devices To sort the grid by a specific column, select the Sort button in the column you want to sort by. Use the arrow buttons that appear to sort ascending or descending.
Filter devices shown 1. In the column that you want to filter, select the Filter button .
2. In the Filter box, define your filter value.

Filters aren't saved when you refresh the Device Inventory page.
Save a filter To save the current set of filters, select the Save As button that appears in the filter row.
Load a saved filter Saved filters are listed on the left, in the Groups pane.

1. Select the Options button in the toolbar to display the Groups pane.
2. In the Device Inventory Filters list, select the saved filter you want to load.

For more information, see Device inventory column reference.

Export the device inventory to CSV

Export your device inventory to a CSV file to manage or share data outside of the OT sensor.

To export device inventory data, select the Import/Export file button, and then select one of the following:

  • Export Device Inventory View: Exports only the devices currently displayed, with the current filter applied
  • Export All Device Inventory: Exports the entire device inventory, with no filtering

Save the exported file locally.

Add to and enhance device inventory data

Use information from other sources, such as CMDBs, DNS, firewalls, and Web APIs, to enhance the data shown in your device inventory. For example, use enhanced data to present information about the following items:

  • Device purchase dates and end-of-warranty dates
  • Users responsible for each device
  • Opened tickets for devices
  • The last date when the firmware was upgraded
  • Devices allowed access to the internet
  • Devices running active antivirus applications
  • Users signed in to devices

Added and enhancement data is shown as extra columns, in addition to the existing columns available in the on-premises management console Device inventory page.

Enhance data by adding it manually or by running a customized version of our automation script sample. You can also open a support ticket to set up your system to receive Web API queries.

For example, the following image shows an example of how you might use enhanced data in the device inventory:

Diagram of the data integrator.

To enhance your data manually:

  1. Sign in to your on-premises management console, and select Device inventory.

  2. On the top-right, select the Settings button to open the Device Inventory Settings dialog.

  3. In the Device Inventory Settings dialog box, select ADD CUSTOM COLUMN.

  4. In the Add Custom Column dialog box, add the new column name using up to 250 UTF characters.

  5. Select Manual > SAVE. The new item appears in the Device Inventory Settings dialog box.

  6. In the upper-right corner of the Device Inventory window, select the Import/Export file button > Export All Device Inventory.

    A CSV file is generated with the data displayed.

  7. Download and open the CSV file for editing, and manually add your information to the new column.

  8. Back in the Device inventory page, at the top-right, select the Import/Export file button again > Import Manual Input Columns. Browse to and select your edited CSV file.

The new data appears in the Device Inventory grid.

Retrieve device inventory data via API

You can retrieve an extensive range of device information detected by managed sensors and integrate that information with partner systems.

For example:

  1. Retrieve sensor, zone, site ID, IP address, MAC address, firmware, protocol, and vendor information.

  2. Filter that information based on any of the following values:

    • Authorized and unauthorized devices.

    • Devices associated with specific sites.

    • Devices associated with specific zones.

    • Devices associated with specific sensors.
