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 part of Comodo Internet Security Pro 2012, which for just $4.99 per year includes—GeekBuddy®—a 24 hour per day, unlimited incident support services package which retails at $49.95 per year. Try it FREE for 30 days!

Firewall Software Frequently Asked Questions
- What's a Firewall?
- Firewall protection is a batch of security measures for your PC, designed to keep malware, viruses, and hackers at bay.
- And how is Comodo Free Firewall software different from the dozens of other firewalls out there?
- Our firewall software is the only true firewall protection operating with Default Deny Protection technology to ensure your computer's security.
- Sounds like Default Deny is important.
- It is. DDP™ grants you, the user, ultimate control of what's granted access to a PC.
- But I'm not making every decision, right? I couldn't handle that.
- Not at all! Our free firewall software has access to Comodo's safe-list of over two million known PC-friendly applications. When one of them accesses your PC, the firewall won't bother you because there's no reason to worry.
- OK, but what if a file I don't recognize asks for access?
- Our free firewall contains detailed alerts letting you know the severity of the threat, and the type of file asking to execute.
- Will programs run OK in the Sandbox?
- 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.
- Do programs stay in the Sandbox forever?
- 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.
