I currently use TinyWall Firewall, it works very well, it’s small/portable, no complaints I even donated to the Dev but I would really prefer open source, also it needs to be user friendly like TinyWall so my non-tech family members can/will use it like they do with TinyWall.
There seems to be a misunderstanding:
- A “firewall for” is something one needed with Windows XP and earlier, as in “a piece of software that acted as a firewall”.
- Nowadays, both Windows 7+ and Linux come with a built-in firewall, that one might want a “GUI for {}'s firewall”.
One of such GUIs, is TinyWall, that is also FOSS (GPLv3). I see people have suggested some more.
To be precise, all these options are inferior in functionality to firewalls like ZoneAlarm… but since you’re asking for a non-tech friendly solution, they should be adequate.
Does Suricata or Snort allow the user to block per-process outgoing traffic?
Both do deep packet inspection using netflow protocol and filter using crowd sourced detection rules as well as commercial, process-level filtering on a host operating system to detect network intrusion is unecessarily resource intensive.

ZenArmor does the same as both, but also uses python scripts with a fancy graphical interface.
