Comodo Free Firewall is a superb replacement for Windows’ default utility. The interface is modern, sleek and intuitive and easy to navigate. Not only is it pleasing on the eyes, it also provides enhanced protection via a constantly updated cloud database to always keep your system as safe as possible.

Key Features include:

• Fast and hassle-free online experience.
• Manages traffic on your PC.
• Blocks all Internet attacks.
• Secures all connections when you are online.
• Monitors in/out connections.

This free firewall protects your computer from all manner of external threats in an efficient and effective way. It uses something called default deny protection (DDP) to prevent any threats from entering, and affecting your system. It works by using a cross reference system to ensure that whenever unknown software has been introduced to your system, Comodo Free Firewall will cross-reference it with a white-list of over 15 million files and apps to see if it is legitimate. If it isn’t then Comodo Free Firewall will alert you that a possibly malicious file is attempting to access your PC.

Overall, Comodo Free Firewall is able to block online threats, providing a solid, strong defence for your system against attacks. It includes a robust browser, virtual desktop and sandboxing system. The only downside is the it flags both good and bad files, which can obviously become quite annoying.
