Antivirus policy for endpoint security in Intune

Intune Endpoint security Antivirus policies can help security admins focus on managing the discrete group of antivirus settings for managed devices. To use Antivirus policy, integrate Intune with Microsoft Defender for Endpoint as a Mobile Threat Defense solution.

Antivirus policy includes several profiles. Each profile contains only the settings that are relevant for Microsoft Defender for Endpoint antivirus for macOS, Windows 10/11, or for the user experience in the Windows Security app on Windows 10/11 devices.

You'll find the antivirus policies under Manage in the Endpoint security node of the Microsoft Endpoint Manager admin center.

Antivirus policies include the same settings as endpoint protection or device restriction profiles for device configuration policy and are similar to settings from device compliance policy. However, those policy types include additional categories of settings that are unrelated to Antivirus. The additional settings can complicate the task of configuring Antivirus. Additionally, the settings found in the Antivirus policy for macOS aren't available through the other policy types. The macOS Antivirus profile replaces the need to configure the settings by using .plist files.

Prerequisites for antivirus policy


  • macOS

    • Any supported version of macOS
    • For Intune to manage antivirus settings on a device, Microsoft Defender for Endpoint must be installed on that device. See. Microsoft Defender for Endpoint for macOS (In the Microsoft Defender for Endpoint documentation)
  • Windows 10 and later

    • No additional prerequisites are required.

Support for Configuration Manager clients:

This scenario is in preview and requires use of Configuration Manager current branch version 2006 or later.

  • Set up tenant attach for Configuration Manager devices - To support deploying antivirus policy to devices managed by Configuration Manager, configure tenant attach. Set up of tenant attach includes configuring Configuration Manager device collections to support endpoint security policies from Intune.

    To set up tenant attach, see Configure tenant attach to support endpoint protection policies.

Prerequisites for tamper protection

You can use Intune to manage tamper protection on Windows devices as part of Antivirus policy. This includes both devices you manage with Intune, and devices you manage with Configuration Manager through the tenant attach scenario.

Intune managed devices

Prerequisites to support tamper protection for devices managed by Intune:

Profiles for Antivirus policy that support tamper protection for devices managed by Intune:

  • Platform: Windows 10 later
    • Profile: Windows Security experience

You can also use the Endpoint protection profile for Device configuration policy to configure tamper protection for devices managed by Intune.

Configuration Manager clients managed through the tenant attach scenario

Prerequisites to support managing tamper protection with these profiles:

  • Your environment must meet the prerequisites for managing tamper protection with Intune as detailed in the Windows documentation.
  • You must use Configuration Manager current branch 2006 or later.
  • You must configure tenant attach to support endpoint protection policies. This includes configuring Configuration Manager device collections for synchronization with Intune.

Profiles for Antivirus policy that support tamper protection for devices managed by Configuration Manager:

  • Platform: Windows 10, Windows 11, and Windows Server (ConfigMgr)
    • Profile: Windows Security experience (preview)

Antivirus profiles

Devices managed by Intune

The following profiles are supported for devices you manage with Intune:


Windows 10:

  • Platform: Windows 10 profiles

    • Profile: Microsoft Defender Antivirus - Manage Antivirus policy settings for Windows 10/11.

      Defender Antivirus is the next-generation protection component of Microsoft Defender for Endpoint. Next-generation protection brings together technologies like machine learning and cloud infrastructure to protect devices in your enterprise organization.

      The Microsoft Defender Antivirus profile is a separate instance of the antivirus settings that are found in the Device Restriction profile for Device Configuration policy.

      Unlike the antivirus settings in a Device Restriction profile, you can use these settings to with devices that are co-managed. To use these settings, the co-management workload slider for Endpoint Protection must be set to Intune.

    • Profile: Microsoft Defender Antivirus exclusions - Manage policy settings for only Antivirus exclusions.

      With this policy, you can manage settings for the following Microsoft Defender Antivirus configuration service providers (CSPs) that define Antivirus exclusions:

      • Defender/ExcludedPaths
      • Defender/ExcludedExtensions
      • Defender/ExcludedProcesses

      These CSPs for antivirus exclusion are also managed by Microsoft Defender Antivirus policy, which includes identical settings for exclusions. Settings from both policy types (Antivirus and Antivirus exclusions) are subject to policy merge, and create a super set of exclusions for applicable devices and users.

    • Profile: Windows Security experience- Manage the Windows Security app settings that end users can view in the Microsoft Defender Security center and the notifications they receive.

      The Windows security app is used by a number of Windows security features to provide notifications about the health and security of the machine. Security app notifications include firewalls, antivirus products, Windows Defender SmartScreen, and others.

Policy path:

  • Endpoint security > Antivirus > Windows 10, Windows 11, and Windows Server (ConfigMgr)


  • Microsoft Defender Antivirus (preview)
  • Windows Security experience (preview)

Required version of Configuration Manager:

  • Configuration Manager current branch version 2006 or later

Supported Configuration Manager device platforms:

  • Windows 11 and later (x86, x64, ARM64)
  • Windows 10 and later (x86, x64, ARM64)
  • Windows Server 2019 and later (x64)
  • Windows Server 2016 (x64)
  • Windows 8.1 (x86, x64), starting in Configuration Manager version 2010
  • Windows Server 2012 R2 (x64), starting in Configuration Manager version 2010

Policy merge for settings

Some Antivirus policy settings support policy merge. Policy merge helps avoid conflicts when multiple policies apply to the same devices and configure the same setting. Intune evaluates the settings that policy merge supports, for each user or device as taken from all applicable policies. Those settings are then merged into a single superset of policy.

For example, you create three separate antivirus policies that define different antivirus file path exclusions. Eventually, all three policies are assigned to the same user. Because the Microsoft Defender file path exclusion CSP supports policy merge, Intune evaluates and combines the file exclusions from all applicable policies for the user. The exclusions are added to a superset and the single list of exclusions is delivered to the users’ device.

When policy merge isn’t supported for a setting, a conflict can occur. Conflicts can result in the user or device not receiving any policy for the setting. For example, policy merge doesn't support the CSP for preventing installation of matching device IDs (PreventInstallationOfMatchingDeviceIDs). Configurations for this CSP don’t merge, and are processed separately.

When processed separately, policy conflicts are resolved as follows:

  1. The most secure policy applies.
  2. If two policies are equally secure, the last modified policy applies.
  3. If the last modified policy can’t resolve the conflict, no policy is delivered to the device.

Settings and CSPs that support policy merge

The following settings support policy merge:
