For communication to flow between the Nebula console and endpoints, you must adjust your firewall and software exclusions. This article lists internal network recommendations, external access requirements, and recommended exclusions that apply to Nebula.
File and Printer Sharing
We recommend using Administrator shared folders to perform network tasks, such as installations. To use them, you must enable File and Printer Sharing on your endpoints.
The location of File and Printer Sharing options depends on which operating system your endpoint uses. Consult your operating system guide for additional information.
External Access Requirements
Allow the following addresses through your firewall or other security software. Endpoint Agents use the sites below to reach Malwarebytes services.
You must allow or exclude all addresses on port 443, outbound.

Notes:
- Malwarebytes does not allow packet-inspection, as this interferes with the service protocols.
- Bypass inspection is required for packet-inspection of Malwarebytes.
- Malwarebytes supports proxy configuration, using built-in functions.
- Pass-through proxy configuration is recommended.
- Dynamic proxy configuration is not supported.
- To test the Endpoint Agent connection, see: Use the Endpoint Agent Command-line tool with Malwarebytes Nebula platform
Antivirus and Firewall Exclusions
If you use additional security software with Malwarebytes, we recommend adding specific software exclusions. These exclusions prevent your other software from conflicting with Malwarebytes. Conflicting security software may range from your network firewall to antivirus.
We recommend that you exclude the following folders and files in your antivirus, firewall, or other software. In addition to the items below, see our specific third-party antivirus software exclusions.
For more information on setting exclusions in Malwarebytes, see Add exclusions to Malwarebytes Nebula.
