System Impact & Resource Usage
Hard Disk Usage: There is no offline installer for the Comodo Firewall. The online installer is about 5 MB in size, which downloads the Comodo Internet Security suite. The CIS suite was of 128 MB at the time of writing this review. After installation, Comodo Firewall used 118 MB of the disk space on my system.
CPU and RAM Usage: Comodo Firewall is one of the most lightweight Firewall programs. It uses only about 15 MB of RAM. The CPU usage is stable at 0%.
User Interface & Ease of Use
Comodo is the only Free Firewall that has an in-built Theme support, the latest version comes with four Skins. There is one for each kind of user. If you like the current Flat design language, then you can use the Modern theme. If you prefer the all glossy colourful design language of the past decade then Classic is the one for you. The default theme of Comodo Firewall is called Lycia, and the one used in Comodo Cloud Antivirus is called Arcadia. So, a lot of options in the theming department.
There are two Home views available for users – Basic View, and Advanced View.

Hi l have used comodo firewall since it was first released years back and l can say without a doubt it is a great firewall to have on any pc for peace of mind l have never had any problems with it at all and will stick with it until comodo goes out of business.
I’ve had similar experience with them, and it has always been one of my most recommended free firewall software. They also make great AntiVirus products thanks to the advanced features such as HIPS and Sandbox, which they provide for free.
