World-Class Protection Against Hackers

Any personal computer connected to the Internet is a potential target. Hackers randomly barrage Internet connected PCs with "pings" or "port scans", probing to find unprotected PCs. Once found, a hacker can compromise your PC with a dangerous Internet threat - Trojan horse, spyware or malicious worm.

ZoneAlarm Pro's TrueVector® technology combines a personal firewall with Program Control to protect your PC from intrusions and hostile attacks. ZoneAlarm Pro's firewall barricades your PC with immediate and complete port blocking. And, then runs in Stealth Mode to make your PC invisible on the Internet - if you can't be seen, you can't be attacked.

Unlike other personal firewalls, ZoneAlarm Pro includes Program Control to protect against known and unknown Internet threats. Program Control monitors all outbound traffic to prevent rogue programs from transferring your valuable data to a hacker. With ZoneAlarm Pro, you're in control with the ability to specify which programs, known or unknown, can be trusted to access the Internet.

With new Internet threats appearing daily, why risk it?

ZoneAlarm Pro - complete protection, complete peace-of-mind.
