Windows has a great built-in firewall, but did you know that there are alternative and completely free firewall programs that you can install? It’s true, and many of them have features and options that are easier to use and understand than the ones that Microsoft has built into its operating system.

Below are 10 of the best free firewall programs I could find. The list is ordered in a very specific way: from actively developed software to software that is no longer updated by its developers. The ones at the bottom of this list are therefore less secure, but may still provide what you need.

Comodo Firewall has useful features such as virtual internet browsing, an ad blocker, custom DNS servers, a game mode, and a virtual kiosk. In addition, you have options to easily block processes or programs from leaving or entering the network.

I especially like how easy it is to add programs to the block or allow list. Instead of going through a long-winded wizard to define ports and other options, you can just browse for a program and go. However, there are also very specific, advanced settings if you want to use them.
