Comodo Personal Firewall is a free (also for commercial use) firewall, providing comprehensive protection against attacks from viruses, trojans, spyware and hackers. The program is part of the Comodo Internet Security package. In addition to the basic functionality of filtering incoming and outgoing traffic, it also offers, among others, the sandbox mechanism (Sandbox).

It allows you to run potentially dangerous software in a virtual environment completely isolated from the operating system. In addition, Comodo Personal Firewall also allows you to create rules for trusted and dangerous applications and hide your computer's presence on the Web. A great advantage of the program is the option that allows you to import/export most of the settings.

With its help we can quickly and easily restore the firewall configuration after reinstalling the system, etc. Comodo Personal Firewall has a friendly and largely user-friendly graphical interface. Its operation, despite its considerable functionality, should not cause problems even for novice users.
