The interface is common and nicely designed, is intuitive and contains only important menus, so you will access fast desired functions.

With right click on application’s icon from bottom right side of your screen, you can easily stop firewall, switch to game mode to not be disturbed or stop internet activity.

You can add custom IPs, web addresses, IP range, subnet to be blocked, trusted or public. ZoneAlarm will have this behavior that you set for each IP or web address.
I have used an online service to text common ports and results are good.
