ZoneAlarm Pro Firewall PDF Print E-mail

ZoneAlarm Pro FirewallZoneAlarm Pro Firewall from Check Point Software Technologies Ltd. (Redwood City, California) is standalone Windows firewall software that stops traffic threats that are arriving or departing from a personal computer. The firewall cooperates with antivirus software and antispyware from competing vendors. Check Point also offers security suites that bundle the firewall with complementary security modules.

ZoneAlarm was a pioneer of firewall protection, offering it for free well before most users even understood the concept of a firewall. It was also one of the first personal firewalls to get "hardened" against attack. I've found no way that a malicious coder could write malware that would break ZoneAlarm's protection.

In addition to effectively protecting your system from outside attack, ZoneAlarm's firewall manages Internet and network access permissions for a vast number of known programs using the company's SmartDefense Advisor database. In testing, it did a good job detecting attempts to evade or subvert program control. While it doesn't actively block exploit attacks the way some high-end commercial firewalls do, the standalone ZoneAlarm firewall is our Editor's choice for free firewall protection.

The OSFirewall feature watches all running applications and warns if it detects suspicious activities. Behavior-based detection features like this one often yield false positives—valid programs identified as suspicious—and OSFirewall is no exception.

Firewall Performance : 9/10

Firewalls serve to protect by preventing infections. When infections sneak past the firewall, they become the responsibility of other guardians, namely antivirus software and antispyware. Once upon a time, the ZoneAlarm Pro Firewall included privacy control and scanned incoming email. Now that browsers have web-privacy controls and email applications scan incoming attachments, Check Point has streamlined ZoneAlarm Pro Firewall to avoid redundant functionality.

Security Features : 9/10

Other noteworthy features include the ability to analyze the potential danger of a downloaded program and the ability to authenticate when and where a website was registered and whether it is dangerous or safe. Although ZoneAlarm Pro does not scan incoming email, it does scan outgoing email for malignancies. The product includes an option to test a download in a safe virtual environment in case it manifests dangerous characteristics.

ZoneAlarm Pro Firewall includes many thoughtful touches that make it easy to be safe. Novices and experts can select appropriate configuration/management levels. If the firewall detects that it is in danger of being hijacked or sabotaged, it retreats into a completely protected state. A toolbar supports the antiphishing and site-status features.

A ZoneAlarm Pro-protected computer offers a dialog box in order set security levels in new network environments without having to open and configure a ZoneAlarm Pro window. The product makes it convenient to include printers and devices in a trusted network zone so that network functionality is not sacrificed to security.

The product can train itself to configure settings based on user behavior. It automatically updates itself to maintain current security lists. Users can control when and why the firewall sends alerts. Alerts are suppressible with one click for times when they might interfere with a game or other application where alerts might intrude on fun.
