Best Free Firewall for Windows 10 in 2022
Using Linux or Mac, you may not need firewall. But to protect your Windows computer from intruders, you must have firewall. Here I have put a small list of best free firewall for Windows 10. These firewall support Windows 10, Windows 8.1, Windows 8, and Windows 7.
Firewall is a network security system which monitors and control outgoing and incoming local or internet traffic on your computer. It follows a set of predefined rules to keep your computer safe. Because of firewall monitoring, it is assumed that the connection to internet is secure. Well, that’s 99% true. The remaining 1% is your common sense which can prevent any hacking attack on your computer. A firewall and your common sense combines makes 100% security.
I have mentioned the supported Windows operating system with every firewall, because one or two do not support Windows 10. I am sure, you will find one which suites you best.
It is strongly advised to use only one firewall. Double firewall installed and active at same time can force your Windows computer to crash and may result in a hardware damage. The download links are given in front of every Firewall name.
Comodo Firewall Free was my favorite among all. I seldom had any problem. That was like install and forget. But a few months ago they pulled the plug and Comodo Firewall is gone. Those who did not uninstall it can still use it as long as they have it installed. But, you cannot install it now as a standalone security tool. You need to buy Comodo Antivirus.
Then there left ZoneAlarm Firewall Free. It is a nice, simple and easy to use piece of software. Almost no complication compared to Comodo Firewall Free if you wanted to configure it. You can also get free Antivirus from ZoneAlarm if you want. So, basically you can get a complete security package free from ZoneAlarm. I could not use free ZoneAlarm Firewall because it conflicts Sticky Password and I need Sticky Password more than ZoneAlarm Firewall.
Well, after Comodo Firewall gone and ZoneAlarm Firewall conflicts with other software, I got Free Firewall which is listed in the table right after Comodo Firewall. I am using it since a few months and it is great in fact. Free Firewall works as intended to be. Give it a try.
Update: Comodo Firewall Free is available again.
Update Jan 04, 2021: Comodo Firewall Free is the best choice for your Windows 10 PC. Nothing beats it. Or you can try Free Firewall which is also great.
