How Firewall works

The Firewall scans all incoming and outgoing traffic.

As it reviews arriving or departing traffic, the Firewall checks its list of rules, which is a set of criteria with associated actions. If the traffic matches all criteria in a rule, the Firewall acts according to the rule, blocking or allowing traffic through the Firewall.

Information about threat detections is saved for reports that notify the administrator of any security issues for your computer.

Firewall options and rules define how the Firewall works. Rule groups organize firewall rules for easy management.

If the Client Interface Mode is set to Full access or you are logged on as administrator, you can configure rules and groups using the Endpoint Security Client. For managed systems, rules and groups that you create might be overwritten when the administrator deploys an updated policy.
