I just watched this interesting video where the PC Security Channel tests whether installing the free opensource TinyWall (features here) on a Windows client can help against info stealers.
To both his and my surprise, it actually worked! So, as a complement to IPFire, it might be worth considering installing another firewall instead of the built-in Windows one, as an example on home computers. Companies often already have dedicated firewalls or endpoint security solutions in place on their clients, but for personal use, tools like TinyWall could be a step up. While TinyWall and similar options may not protect against everything, they are likely to offer better security than the standard built-in firewall.
This almost the first thing to read about it on Git.
" About this repository
This is the source code of TinyWall as found at its website. Upstream development is now largely inactive, but this repository is provided for anyone who would like to submit their own improvements or fork the project."
The most recent changelog is availble on GitHub: TinyWall/Changelog.txt at master · pylorak/TinyWall · GitHub
As you can see there are changes coming up and there will be a new release probably in February. (I will change the link on the homepage to point to the changelog on GitHub).
It is correct though that I am not working on major new features anymore, but I will perform maintenance to fix bugs, to keep it working with newer versions of other software, and to integrate new code/changes submitted by others.
