Firewall protection

Firewall protection is your front line of defense against Internet threats. ZoneAlarm security software’s default Zones and security levels give you immediate protection against the vast majority of threats. If you’re an advanced user, custom port permissions and expert rules give you detailed control of traffic based on source, destination, port, protocol, and other factors.
