In Symantec Endpoint Protection Small Business Edition (SEP SBE) cloud, the local agent proxy settings override the proxy settings in a global System Policy. The global policies are configured in the Management Console Policies page.
The policy-controlled proxy settings that are configured within the Management Console are applied to selected groups in your organization. Before you implement proxy settings from the Management Console, Symantec recommends testing the intended configuration on a number of test computers first. Incorrectly configuring Proxy Settings in the management console risks locking out all of your cloud agents. Fortunately, the Endpoint Protection agent interface can override an errant configuration, but the correction requires manual intervention.
To configure proxy settings for a computer using the Endpoint Protection agent user interface
Double-click the Symantec.cloud icon in the notification area.
When the user interface opens, click Settings in the banner bar.
Click Proxy Settings from the Settings menu.
Activate the Override Proxy Settings check-box.
Activate the Enable Proxy check-box in the proxy configuration portion of the window.
Enter the Host and Port addresses for the proxy.
Activate the Authenticated check-box if authentication to the proxy is required and enter a User name and Password.
When you are finished, click Apply and Close to save your configuration.
