Pros Its Defense+ HIPS performance exceeds commercial products and leads the class, it includes an excellent "memory firewall" feature, and it allows you to quickly switch between Defense+ security modes and configurations. Includes automatic updates. Installation can automatically configure your PC to use the Comodo SecureDNS (but you can do this without installing CIS).

Why use our Firewall?
Comodo Firewall Pro introduces the next evolution in computer security: Default Deny Protection (DDP™). What is DDP? Most security programs maintain a list of known malware, and use that list to decide which applications and files shouldn't access a PC. The problem here is obvious. What if the list of malware is missing some entries, or isn't up to date? DDP fixes this problem to ensure complete security. The firewall references a list of over two million known PC-friendly applications. If a file that is not on this safe-list knocks on your PC's door, the Firewall immediately alerts you to the possibility of attacking malware. All this occurs before the malware infects your computer. It's prevention-based security, the only way to keep PCs totally safe.
Firewall is a component of Comodo Internet Security 2011, which comes bundled with Comodo Antivirus. You have the option to only install Firewall if you prefer.
Firewall is also a part of Comodo Internet Security Pro 2011, which gives you the most robust defense and inlcudes other components like WiFi security, live 24/7 expert assistance for numerous computing needs. 
Firewall Features:
  • Easily understood and informative alerts
  • No complex configuration issues—perfect for amateur users
  • Lots of configuration options let techies configure things just as they like
  • DDP-based security keeps you informed and PCs safe
  • Quickly learns user behavior to deliver personalized protection
  • User-friendly, attractive graphical interface
One of the first steps in securing a computer is downloading and activating a quality firewall to repel intruders. Only this free firewall software has access to Comodo's extensive safe-list of PC-friendly applications, a key component of Default Deny Protection™. Check out our firewall software today or upgrade to 360-degree protection with Comodo Internet Security Pro 2011.

 Online Armor Free    Rating 9 of 10

Pros Excellent proactive security performance. Includes a "run safer" feature to reduce rights for specific risky applications, and the ability to monitor key logger activity and host files. It handles the installation of new programs better than many other tested products.
Cons It doesn't have automatic updates or a built-in help. It's mandatory to enter an email during installation, and it has a pre-checked option to send it anonymous information.

 Privatefirewall    Rating 8 of 10

Pros Effective proactive security and stealth, one of the lightest of all tested firewalls on memory, simple setup (no nags or ads!). Easily choose between 3 network profiles. Has a unique "email/system anomaly detection" feature, which trains over 7 days by default.
Cons Ineffective self-protection, fails a leak test (see echo2), and fails some tests for prevention of malicious system shutdowns. It doesn't have an automatic installation mode (but it has a training mode in "Settings" > "Advanced"). The tray icon flashes for log events instead of network activity per se. No update feature.
