The Device inventory shows a list of the devices in your network where alerts were generated. By default, the queue displays devices seen in the last 30 days.

At a glance, you see information such as domain, risk level, OS platform, and other details for easy identification of devices most at risk.

Note

The device inventory is available in different Microsoft Defender XDR services. The information available to you will differ depending on your license. You'll get the most complete set of capabilities when using Microsoft Defender for Endpoint Plan 2.

Note

Risk Level which can influence enforcement of conditional access and other security policies on Microsoft Intune, is available in Windows today.

There are several options you can choose from to customize the devices list view. On the top navigation you can:

  • Add or remove columns
  • Export the entire list in CSV format
  • Select the number of items to show per page
  • Apply filters

During the onboarding process, the Devices list is gradually populated with devices as they begin to report sensor data. Use this view to track your onboarded endpoints as they come online, or download the complete endpoint list as a CSV file for offline analysis.

Note

If you export the device list, it will contain every device in your organization. It might take a significant amount of time to download, depending on how large your organization is. Exporting the list in CSV format displays the data in an unfiltered manner. The CSV file will include all devices in the organization, regardless of any filtering applied in the view itself.

The list of devices

Sort and filter the device list

You can apply the following filters to limit the list of alerts and get a more focused view.

Device name

During the Microsoft Defender for Endpoint onboarding process, devices onboarded to Defender for Endpoint are gradually populated into the device inventory as they begin to report sensor data. Following this, the device inventory is populated by devices that are discovered in your network through the device discovery process. The device inventory has three tabs that list devices by:

  • Computers and Mobile: Enterprise endpoints (workstations, servers, and mobile devices)
  • Network devices: Devices like routers and switches
  • IoT devices: Devices like printers and cameras
  • Uncategorized devices: Devices that couldn't be properly classified

Navigate to the Device inventory page

Access the device inventory page by selecting Devices from the Assets navigation menu in the Microsoft Defender portal.

Device inventory overview

The device inventory opens on the Computers and Mobile tab. You can see at a glance information such as device name, domain, risk level, exposure level, OS platform, criticality level, onboarding status, sensor health state, mitigation status and other details for easy identification of devices most at risk.

The Classify critical assets card allows you to define device groups as business critical. You might also see the Attack path warning card, which takes you to Attack paths to examine if any of your assets are part of an attack path. For more information, see Overview of attack paths.

Note

Classify critical assets and attack path information is part of Microsoft Security Exposure Management, which is currently in public preview.

Use the Onboarding Status column to sort and filter by discovered devices, and devices that are already onboarded to Microsoft Defender for Endpoint.

Note

Device discovery Integration with Microsoft Defender for IoT is available to help locate, identify, and secure your complete OT/IOT asset inventory. Devices discovered with this integration will appear on the IoT devices tab. For more information, see Device discovery integration.

When Defender for IoT is configured, you also can view the devices there. See Manage your IoT devices with the device inventory for organizations.

At the top of each device inventory tab, you can see:

  • The total number of devices.
  • The number of devices that are identified as a higher risk to your organization.
  • The number of your business critical assets.
  • The number of devices that aren't yet onboarded.
  • The number of devices with high exposure.
  • The number of newly disocovered devices.

You can use this information to help you prioritize devices for security posture improvements.

The Newly discovered device count for network devices and IoT devices tabs, shows the number of new devices discovered, in the last 7 days, listed in the current view.

Explore the device inventory

There are several options you can choose from to customize the device inventory view. On the top navigation for each tab you can:

  • Search for a device by name
  • Search for a device by the most recently used IP address or IP address prefix
  • Add or remove columns
  • Export the entire list in CSV format for offline analysis
  • Select the date range to display
  • Apply filters

Note

If you export the device list, it will contain every device in your organization. It might take a significant amount of time to download, depending on how large your organization is. Exporting the list in CSV format displays the data in an unfiltered manner. The CSV file will include all devices in the organization, regardless of any filtering applied in the view itself.

You can use the sort and filter functionality available on each device inventory tab to get a more focused view, and to help you assess and manage the devices in your organization.

The counts on the top of each tab are updated based on the current view.

Use filters to customize the device inventory views

Filter Description
Risk level The risk level reflects the overall risk assessment of the device based on a combination of factors, including the types and severity of active alerts on the device. Resolving active alerts, approving remediation activities, and suppressing subsequent alerts can lower the risk level.
Exposure level The exposure level reflects the current exposure of the device based on the cumulative impact of its pending security recommendations. The possible levels are low, medium, and high. Low exposure means your devices are less vulnerable from exploitation.

If the exposure level says "No data available," there are a few reasons why:
- Device stopped reporting for more than 30 days. In that case it's considered inactive, and the exposure isn't computed.
- Device OS not supported - see minimum requirements for Microsoft Defender for Endpoint.
- Device with stale agent (unlikely).
Criticality level The criticality level reflects how critical a device is for your organization. The possible levels are low, medium, high, or very high. Very high means that the device is considered a business critical asset. For more information, see Overview of critical asset management.
OS Platform Filter by the OS platforms you're interested in investigating

(Computers and mobile and IoT devices only).
Windows version Filter by the Windows versions you're interested in investigating. If 'future version' appears in the Windows version field, it can mean:

- This is a pre-release build for a future Windows release
- The build has no version name
- The build version name isn't yet supported

In all these scenarios, where available, the full OS version can be seen in the device details page.

(Computers and mobile only).
Sensor health state Filter by the following sensor health states, for devices onboard to Microsoft Defender for Endpoint:
- Active: Devices that are actively reporting sensor data to the service.
- Inactive: Devices that stopped sending signals for more than seven days.
- Misconfigured: Devices that have impaired communications with service or are unable to send sensor data.
Misconfigured devices can further be classified to:
- No sensor data
- Impaired communications
For more information on how to address issues on misconfigured devices, see, Fix unhealthy sensors.

(Computers and mobile only).
Onboarding status Onboarding status indicates whether the device is currently onboarded to Microsoft Defender for Endpoint or not. Device discovery must be enabled for this filter to appear. You can filter by the following states:
- Onboarded: The endpoint is onboarded to Microsoft Defender for Endpoint.
- Can be onboarded: The endpoint was discovered in the network as a supported device, but isn't currently onboarded. Microsoft highly recommends onboarding these devices.
- Unsupported: The endpoint was discovered in the network, but isn't supported by Microsoft Defender for Endpoint.
- Insufficient info: The system couldn't determine the supportability of the device.

(Computers and mobile only).
Antivirus status Filter the view based on whether the antivirus status is disabled, not updated or unknown.
