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.

I'm using Comodo's free firewall for a while now and I assure you this is a very good software that guarantees a policy-based control that takes care of security when you are online.
Superb firewall embedded with a strong prevention-based mechanism. Offers in-built security features, blocks unsafe URLs, and helps to manage web traffics.
I'm just here to add my two cents about what a wonder tool Comodo Firewall really is. The program has easy to follow and implement features, with a wide variety of customizable services. No wonder CNET gave it an editor's choice award. That's well deserved!
This is better than Windows firewall application. Comodo is the best workstation software firewall solution in the market.

Firewall protection is a batch of security measures for your PC, designed to keep malware, viruses, and hackers at bay.
It is. DDP™ grants you, the user, ultimate control of what's granted access to a PC.
Yes. Applications in the sandbox are run under a carefully selected set of privileges and will write to a virtual file system and registry instead of the real system. This means untrusted (but harmless) applications have the freedom to operate as usual while malicious programs are prevented from accessing or infecting your computer. This provides smoothest and most secure user experience possible....read more

No – the sandbox is the first part of a trust decision engine. After an unknown application has been placed in the sandbox, Internet Security will also automatically queue it for submission to Comodo labs where it will be analyzed by our technicians. If it is found to be harmless then it will be added to the global safe list that will be downloaded by all Internet Security users in the next round of updates. Once it is added to the safe list, the application will no longer be run in the sandbox by Internet Security. If it is found to be malicious then it will be added to Comodo's list of malware signatures and will be deleted after the next round of updates....read more
