Configuring Exclusions

When adding exclusions to Microsoft Defender Antivirus, you should be mindful of Common Exclusion Mistakes for Microsoft Defender Antivirus

Network connections

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 may need to create an allow rule specifically for them.

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.
