A free version of a popular firewall application.

A computer connected to the Internet is subject to intrusion by malicious users. The best remedy against this danger is a firewall such as ZoneAlarm.

ZoneAlarm is a free firewall with more than a decade of experience. Once installed, your computer is behind an impermeable wall in which only you can authorize the passage of data between programs and the network.

The golden age of free firewalls ended when Microsoft decided to include a firewall in Windows XP. ZoneAlarm has suffered, thus a significant reduction in number of users and popularity.

It looks cooler than the original and it certainly does seem to have less configuration options and features. Still, ZoneAlarm is still an excellent firewall.
