    Probably the best firewall available for Windows right now. You can pass it lists of IPs from the internet and it will periodically re-fetch them and keep your block list updated. Its neat, it doesn't lag the system and overall its way better than Windows Defender.

    The OpenSnitch equivalent to Windows.

    Great software Firewall, with many features you usually have with paid software firewalls. Many functionalities, ad-free and open source. (hosted on github) My absolute favorite after simplewall for many years.

Comment summary: Fort Firewall is widely praised for its open-source flexibility, ease of use, and feature richness without being bloated. It supports unique features like path wildcards and traffic shaping, allowing users ease in creating and managing application groups. While it's not perfect, lacking a domain blocker and requiring improvement in traffic shaping usability, many find it comparable or superior to SimpleWall. The portability and continuous improvements add to its appeal as a reliable firewall option.

Pros:

  1. Simple and efficient
  2. No bloatware
  3. Grouping
  4. Traffic-shaping
  5. Scheduling
  6. Statistics
  7. Works with UWP-Apps & Services
  8. Neat simplistic interface
  9. Is able to kill processes not just block them
  10. Open source
  11. PORTABLE! (optional) and still automatic updates (oh yes!)
  12. Active and caring dev!
  13. Recently added: Port- & Protocol-filtering
  14. Recently added: Complex rules

Cons: 1̶. N̶e̶i̶t̶h̶e̶r̶ p̶o̶r̶t̶-̶ n̶o̶r̶ p̶r̶o̶t̶o̶c̶o̶l̶-̶f̶i̶l̶t̶e̶r̶i̶n̶g̶ Y̶E̶T̶. 2. No server/client-setup possible YET. 3̶. N̶o̶ c̶o̶m̶p̶l̶e̶x̶ r̶u̶l̶e̶s̶ p̶o̶s̶s̶i̶b̶l̶e̶ Y̶E̶T̶.

To me the perfect (and only real) simplewall-alternative. To be precise: The best (FOSS) Firewall there is.

Kodi, thanks for kind review.

  1. No server/client-setup possible

Can you please create issue on Github?

Kodi Jack

There already is one ("Centralized management for the enterprise environment #246") :-)

Nodir Temirkhodjaev

Kodi, with v3.14.13 you can tick off the 1) and 3) of Cons.

Kodi Jack

You're awesome, thanks! And ticked off they are :)

What didn't you like that made you leave 4 stars?

You can´t block inbound connections easily.

very good third-party firewall for Windows 10/11.

Allows you to block telemetry spyware by adding a list of...

And many other functions...

Maybe a lot of alerts and having to disable kernel isolation can compromise overall Windows security...

very light,

the portable version is not recommended.

Possibility of exporting settings, etc., so very good tools!

good support from the designer.

Nodir Temirkhodjaev

the portable version is not recommended.

The portable installation is for who understands how it works and how to update it properly.

Perfect replacement for simplewall and even easier to use in my case! It also filters svchost.exe services which is extremely useful and allows great granularity!

Unlike FAB and similar UIs for the built-in firewall, this one can remove missing programs all at once. It has a separate window to control services. Uses the white list principle. Learns. Has both the black and white list modes. It installs a service.
