Free firewall tools for Windows

I’ve recently had many friends and relatives inquiring about free antivirus software (to be covered in another post later on) and firewalls for use on their computers. Of course there are suites like Norton Internet Security and Kaspersky Internet Security which provide both firewall and antivirus tools embedded in a single setup, but still many people prefer to use free ones instead of buying a one year license and then have the hassle to renew them when they expire, while some say that these suites usually “bloat” their systems and make them feel slower.

Here is a list of a few free firewalls which I’ve used in the past (and currently):

1. ZoneAlarm Free Firewall:

One of the most popular and widely used firewall software for Windows. It blocks hackers and prevents viruses & spyware from stealing your personal data and sending it out to the Internet. It works great with almost all antivirus software. Its a 2-way firewall so it also prevents your personal information to be sent on Internet.


2. Comodo Firewall:

Comodo firewall exists as a stand-alone app, as well as with the free Comodo Internet Security suite available from its official website. Its very lightweight program which comes with simple and easy to use interface, and has a good configuration profile, along with secure DNS options provided by Comodo servers.

3. Outpost Security Suite:

Outpost Security Suite comes with a fully functional antivirus, anti-spyware and firewall program.


4. Online Armor:

Online Armor is another free firewall available for Windows. Its setup process is straightforward and configuration is a one-time event and part of the initial installation process. It provides complete protection from inbound threats and control of data leaving your computer for the internet.


5. Ashampoo Firewall Free:

The program provides automatic notifications when an app attempts to connect to the Internet and gives you the power to block or allow such actions. You can also go in and add rules for programs manually, along with viewing connection stats and logs. However this firewall is somewhat an outdated version due to no more development being done on it.


6. Windows Firewall:

Of course, Windows provides its own firewall tool which can be used, but it does not possess the same capabilities present in third-party ones. But it’s always a good idea to activate it, unless third-party ones need it to be disabled to allow them protect your system instead.

Feel free to share your own free firewall tools which you use in the Comments section.

  1. I use the integrated Windows Firewall tool. Never needed to worry about any security issue. Anyway it’s just a computer for a personal use, and we also have to be careful what we do with the internet! 😉


    • I do not discredit the built-in Windows firewall, however for a better protection, I do use the third party ones as they seem to be more powerful and can be customized to a larger extent as well when required 😛
      And also you never know when and how security can be compromised, even for personal use
