The quality of the software, especially the installer is a complete mess.

if you don't block internet access for comodo firewall itself, it still sends some kind of anti-virus file analyzes home to comodo. you have to uncheck so many things in the settings you don't want if you only want a firewall functionality. That's just about the install process.Įven if you manage to only install the Firewall, it has still a lot of functionality that has nothing to do with a firewall but rather an anti-virus software. It also downloads all unwanted software first, even if you don't want it to be installed. Then, someday they got rid of the offline installer making it mandatory to use their web installer, which, before you install the comodo firewall, analyzes your PC and then already sends some of that information home to comodo. If it happens that you install this stuff you might end up with security flaws because comodo installs their own certificates to capture and analyze ssl traffic. You get the firewall bundled with other nonsense bloatware and it's very tricky to not install unwanted software.

However, there are several reasons which makes the use of comodo firewall unbearable: I was very happy with the comodo firewall, it has still a lot more functionality than simplewall and due to it's kernel level it's working for all users on the system and it can be activated for specific network devices only. I've been using comodo firewall for many years before I got rid of it in favor of simplewall one or two years ago.
