Thank you! That’s exactly what I was looking for. I am familiar with Little Snitch for macOS, so this looks perfect.

For anyone interested: https://github.com/evilsocket/opensnitch

If you’re on windows run glass wire or OSX run little snitch. I used to know a Linux alternative for those

Would you happen to know the name of a similar tool for Linux? I was just yesterday searching myself but I couldn’t find anything
