Filtering modes

Three filtering modes are available for the ESET Cyber Security Pro firewall. Filtering mode settings can be found in ESET Cyber Security Pro preferences (press cmd+,) > Firewall. The behavior of the firewall changes based on the selected mode. Filtering modes also influence the level of user interaction required.

All traffic blocked - all inbound and outbound connections will be blocked.

Auto with exceptions - the default mode. This mode is suitable for users who prefer easy and convenient use of the firewall with no need to define rules. Automatic mode allows standard outbound traffic for the given system and blocks all non-initiated connections from the network side. You can also add custom, user-defined rules.

Interactive mode – allows you to build a custom configuration for your firewall. When a communication is detected and no existing rules apply to that communication, a dialog window reporting an unknown connection will be displayed. The dialog window gives the option of allowing or denying the communication, and the decision to allow or deny can be remembered as a new rule for the firewall. If you choose to create a new rule at this time, all future connections of this type will be allowed or blocked according to the rule.


To record detailed information about all blocked connections to a log file, select Log all blocked connections. To review the firewall log files, from the main menu click Tools > Logs and select Firewall from the Log drop-down menu.
