Hi,

If you want Symantec Endpoint Protection Manager to go through a proxy server to connect to the Internet, you must configure Symantec Endpoint Protection Manager to connect to the proxy server. A proxy server can add a layer of security because only the proxy server is connected directly to the Internet.
