ZoneAlarm is a free firewall from ZoneLabs. ZoneAlarm is designed to protect
your DSL or cable-connected PC from hackers.
This program includes four interlocking security services: a firewall, an
application control, an Internet lock, and zones. The firewall controls the
door to your computer and allows only traffic that you understand and initiate.
The application control allows you to decide which applications can and cannot
use the Internet. You can always search The File Database
for more information about a process. The Internet lock blocks Internet traffic while your computer
is unattended or while you are not using the Internet, and it can be activated
automatically with your computer's screensaver or after a set period of inactivity.
Zones monitor all activity on your computer and alert you when a new application
attempts to access the Internet.
ZoneAlarm Free is Windows 98/NT/2000/XP compatible.
