Comodo Firewall, rated by PC Magazine Online as an Editor's Choice, constantly monitors and defends your PC from internet attacks. It's easy to install and use and passes the industry's most stringent firewall "leak" tests. Unlike some other 'free' firewalls, this is not a stripped down version but is the full, completely functional product. This free solution comes complete with continual updates that are free forever!

As Internet access becomes vital to all business organizations, network security and privacy affects everyone. Comodo, a leading global provider of trust and assurance services for the Internet, provides the highest level of protection for networks and home users alike.
Comodo Firewall Pro is one of the smartest firewalls you can ever see. While providing answers to firewall questions, users usually do not understand the complex questions which involve complicated connection details like IP addresses, Ports, Application paths etc.
Comodo Firewall Pro helps you to understand what is going on by analyzing each alert and providing you an intuitive, easily understandable Security Considerations section with each question it asks.

With its built-in application database, Comodo Firewall Pro classifies more than 10.000 applications according to their risk level such as SAFE, SPYWARE, ADWARE etc. It is the only firewall which has such a big application database and which uses such a database to analyze the security risks.

Jetico Personal Firewall 2.0.0.34

www.jetico.com

The Jetico Personal Firewall offers detailed, configurable event logs, reports, plus the option to view and edit the firewall configuration. The modular architecture is as open as possible to assist with easier evaluation of the security.

The Jetico Personal Firewall enables you to:

• Protect your computer against hackers and malicious software when networked or connected to the internet.
• Choose a pre-defined Security Policy.
• Edit an existing Security Policy (i.e. the firewall rule set configuration).
• Create your own Security Policy.
• Monitor running applications that access the network.
• Monitor selected/all network packets as well as selected network events.

Three-layer protection:

I. Low-level. (Network packet filter). This checks the validity of network packets and parameters such as source & destination addresses, protocol, etc. Using this process, Jetico Personal Firewall can make your computer invisible to a non-trusted network. By selecting the Optimal Protection Policy, your computer becomes "stealthy". Any security probing tests (for example, ShieldsUp! tests) by internet hackers will report that your computer does not exist.

II. Application-level. (Network events filter). This checks and enables you to monitor network/internet connection requests made by applications. If you are not sure why an application wishes to send or receive data from the Internet you can limit or block the activity.

III. User-level. (Process activity filter). This notifies you of and prevents dirty tricks by Trojans and other malicious programs. (A Trojan can inject its own code into programmes on your computer and send data about you to a third party. e.g. a Trojan in Internet Explorer could transmit details of your browsing preferences.)

Sunbelt Kerio Personal Firewall 4.5.916

www.sunbelt-software.com

Sunbelt Personal Firewall is the Windows IT Pro Readers' Choice Award winner for best desktop firewall! It was also the least expensive firewall among the top three contenders, proving that affordability doesn't have to compromise quality. SPF4 offers the hacker-proof security of a leading firewall for half the cost of the competition.

The Windows XP firewall gives many people a false sense of security. Unlike SPF4 and other leading stand-alone firewall software, the XP firewall does not block information going out of your PC. The bottom line: Your credit card numbers, passwords, account information and more could be sent from your PC to a hacker, without the XP firewall even detecting the breach.

This costs $19.95 to buy (with a 30-day money-back guarantee), but after the 30-day trial will keep working, but in basic mode.

Note: Sunbelt Personal Firewall is not compatible with Windows Vista..

ZoneAlarm 7.0.362.0

www.zonelabs.com

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 you understand and initiate. The application control allows you to decide which applications can and cannot use the Internet. The Internet lock blocks Internet traffic while your computer is unattended or while you're 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 is free for individual and not-for-profit charitable entity use (excluding governmental entities and educational institutions).
