Comodo Firewall 5.9

CNET Editors' review

by: CNET staff on May 07, 2012

If you're running a fairly recent edition of Windows, you're probably also using the built-in Windows Firewall. It does a good job, but there's no reason not to take advantage of much more capable (yet just as free) firewalls, especially when they're easier to use and come with significant extras. Take Comodo Firewall: This full-featured, multilayer firewall application uses cloud-based data to analyze new programs and data to prevent attacks, including zero-day attacks. It protects your system from viruses, Trojans, worms, hacker attacks, and other threats. Extras include a Geek Buddy subscription, the SecureDNS network, and a speedy, secure Web browser, Comodo Dragon.

Comodo Firewall's setup includes three network locations, with appropriate security levels for each: Home, Work, and Public. We chose Home. Comodo Firewall's operation is very much like other firewalls we've tried: the first time you use a program or access a Web site with the firewall running, you need to enable it in a pop-up that remembers your choice unless you tell it otherwise. The firewall's system tray icon accesses a menu that let us configure the Firewall and Defense & Security levels, and also its Sandbox feature and Game Mode.

Setup required a reboot, as did some settings, such as the Proactive Security Configuration. A simple, colorful interface gave us quick access to the two main components, the Firewall and Defense+ features. In daily use, Comodo Firewall is every bit as unobtrusive and easy to manage as the most popular free standalone firewalls for Windows, and just as flexible. It also includes lots of help options, such as the Geek Buddy feature and online forums and documentation.

We also like Dragon, which we updated shortly after installing it. Dragon automatically imported favorites, history, passwords, and other data we specified from our default browser (Chrome) including our bookmarks toolbar (thanks). Dragon is Chrome's cousin; it's based on the Chromium engine. Dragon is great for trying SecureDNS without altering your network settings. The SecureDNS network offers various security features, and it didn't slow down our browsing. Comodo Firewall is a top contender among free firewall applications.

Publisher's Description

From Comodo:

Comodo's free Firewall is your first layer of defense against viruses, worms, Trojans, hackers and all Internet threats. Comodo's Firewall uses Default Deny Protection to prevent threats from occurring, rather than just detecting them when it's already too late. Whenever an unknown piece of software is introduced to your system, Comodo Firewall cross-references it with a white-list of over 15 million trusted files and applications. If the file asking for access is on the list, Comodo Firewall can be sure it's safe for your computer to allow it to execute. If not, Comodo Firewall will alert you that a possibly malicious file is trying to enter your PC. The latest version sees a major leap forward in security and usability with the addition of cloud based scanning and behavior analysis of unrecognized files - making Comodo Firewall unbeatable at detecting zero-day attacks. Under default settings, unknown and untrusted files are automatically scanned by our cloud-based virus scanners then, while the file undergoes behavior analysis on our cloud server, it is run in a virtual environment (sandbox) on your local machine so that it cannot modify or affect data on your 'real' system. This ground-breaking method of protecting your PC means that only trusted applications are allowed to run. Malware and untrusted files get nowhere near anything important AND you get to use your computer without interruption from nagging alerts. The software also boasts a powerful packet filtering firewall that helps you securely connect to the internet while blocking hackers from making incoming connections. It's easy to use and features an attractive interface that lets even beginners change settings to their liking. Comodo Firewall comes with automatic updates and is winner of the prestigious Editor's Choice award from PCMag.com. Download it now and find out why prevention-based protection is the security technology of the future. Comodo Firewall is completely free for life.
