List of supported kernel versions
Microsoft Defender for Endpoint on Red Hat Enterprise Linux and CentOS - 6.7 to 6.10 is a Kernel based solution. You must verify that the kernel version is supported before updating to a newer kernel version. See the list below for the list of supported kernels. Microsoft Defender for Endpoint for all other supported distributions and versions is kernel-version-agnostic. With a minimal requirement for the kernel version to be at or above 3.10.0-327.
fanotifykernel option must be enabled
- Red Hat Enterprise Linux 6 and CentOS 6:
- For 6.7: 2.6.32-573.* (except 2.6.32-573.el6.x86_64)
- For 6.8: 2.6.32-642.*
- For 6.9: 2.6.32-696.* (except 2.6.32-696.el6.x86_64)
- For 6.10:
After a new package version is released, support for the previous two versions is reduced to technical support only. Versions older than that which are listed in this section are provided for technical upgrade support only.
Running Defender for Endpoint on Linux side by side with other
fanotify-based security solutions is not supported. It can lead to unpredictable results, including hanging the operating system. If there are any other applications on the system that use
fanotifyin blocking mode, applications are listed in the
conflicting_applicationsfield of the
mdatp healthcommand output. The Linux FAPolicyD feature uses
fanotifyin blocking mode, and is therefore unsupported when running Defender for Endpoint in active mode. You can still safely take advantage of Defender for Endpoint on Linux EDR functionality after configuring the antivirus functionality Real Time Protection Enabled to Passive mode.
Disk space: 2 GB
An additional 2 GB disk space might be needed if cloud diagnostics are enabled for crash collections.
/opt/microsoft/mdatp/sbin/wdavdaemon requires executable permission. For more information, see "Ensure that the daemon has executable permission" in Troubleshoot installation issues for Microsoft Defender for Endpoint on Linux.
Cores: 2 minimum, 4 preferred

When adding exclusions to Microsoft Defender Antivirus, you should be mindful of Common Exclusion Mistakes for Microsoft Defender Antivirus.
The following downloadable spreadsheet lists the services and their associated URLs that your network must be able to connect to. You should ensure that there are no firewall or network filtering rules that would deny access to these URLs. If there are, you might need to create an allow rule specifically for them.
|Spreadsheet of domains list||Description|
|Microsoft Defender for Endpoint URL list for commercial customers||Spreadsheet of specific DNS records for service locations, geographic locations, and OS for commercial customers.|
|Microsoft Defender for Endpoint URL list for Gov/GCC/DoD||Spreadsheet of specific DNS records for service locations, geographic locations, and OS for Gov/GCC/DoD customers.|
For a more specific URL list, see Configure proxy and internet connectivity settings.
Defender for Endpoint can discover a proxy server by using the following discovery methods:
- Transparent proxy
- Manual static proxy configuration
If a proxy or firewall is blocking anonymous traffic, make sure that anonymous traffic is permitted in the previously listed URLs. For transparent proxies, no additional configuration is needed for Defender for Endpoint. For static proxy, follow the steps in Manual Static Proxy Configuration.
PAC, WPAD, and authenticated proxies are not supported. Ensure that only a static proxy or transparent proxy is being used.
SSL inspection and intercepting proxies are also not supported for security reasons. Configure an exception for SSL inspection and your proxy server to directly pass through data from Defender for Endpoint on Linux to the relevant URLs without interception. Adding your interception certificate to the global store will not allow for interception.
