Download of the the Month: Sygate Personal Firewall

Sygate's personal firewall pro 5 tied ZoneAlarm Pro 3.1 for best firewall in our July security roundup, "Protect Your PC"). And like Zone Labs, Sygate offers a free version--Sygate Personal Firewall 5--that includes the majority of the commercial version's most important features.

Both ZoneAlarm and Sygate Personal Firewall let you decide whether to permit individual apps to connect to the Net--either as clients or as servers--and both programs block incoming and outgoing attacks by hackers and Trojan horse software. But Sygate offers a feature ZoneAlarm doesn't have. In addition to specifying the exact IP addresses and ports a program may use to communicate with the outside world, you can limit when the program may do so, and for how long. For example, you can set Personal Firewall to allow a chat program online for only an hour each day. Visit our Downloads page to get the 4.6MB file.
