This article applies to all MetaDefender Endpoint releases deployed on Windows, Linux or macOS systems.

Non-Authenticated Proxies

MetaDefender Endpoint is designed to automatically detect a computer’s configured proxy and then apply the same settings.

So, no manual configuration is required for the MetaDefender Endpoint to work with a non-authenticated proxy.

Authenticated Proxies

Authenticated proxies are not supported.

MetaDefender Endpoint will always attempt to connect directly before using a proxy, so either firewall or proxy exceptions will need to be made.
