Do you use LittleSnitch or the equivalent on your OS?
I think I’ve used LittleSnitch since my first ever Mac - does anyone else use it or whatever the equivalent is on your OS?
What does it do?
LittleSnitch is essentially an application firewall/network monitor - it allows you to control which software on your computer can connect to the internet, letting you allow or deny, either for forever, until quit, just once, or for a specified time.
I’ve found it an invaluable tool. You can just deny apps any connection ‘forever’, then when you want to upgrade or allow access you can simply delete the associated rule and it will ask you for permission next time it tries to connect to the internet.
You’d be surprised at how often some apps (like VS Code and the Google Chrome Updater) want to dial home!
Do you use LittleSnitch or the equivalent for your OS?
- Yes
- No
- Considering it now!
Alternatives/similar that I’m aware of (thanks to Dimi, ODL and Dusty posting them on DT):
- https://www.tripmode.ch/ - for macOS (free)
- OpenSnitch - for Linux
- https://santa.dev/ - Santa is a binary and file access authorization system for macOS

Back in my windows days I used to use ZoneAlarm, I am not sure if that software does even still exist or would be sane to use… Not every software form pre 2010 is still fine to use nowadays 
Back when I did the switch, I of course searched for a replacement, just because I was used to use one, though didn’t found anything.
Today I do not consider it much worth anyway. I prefer FOSS over proprietary software, and do support this FOSS via telemetry data, update checking is usually patched out though by the packaging mechanism as on NixOS autoupdaters do usually not work.
Or it is simply software that requires to be online by definition. Like a web browser

If I ever go to the scientific calculation area I should do that, you get more performance that way.

As you say some of it is avoidable, and for me personally, it’s more about the third party apps - perhaps in part because Apple’s marketing and reputation centres around privacy, so if they do something to jeopardise that they will be hurting themselves significantly (so that should be a decent deterrent).

Go with what makes you happy or what you are comfortable with Dimi 
Personally, for me, LittleSnitch is a necessity and the only problem I have with it is… I want it everywhere! On my smart TV, on my phone, on my console, everywhere! 
Perhaps a better LittleSnitch would be a SnitchRouter - i.e a hardware based system which all of your traffic is routed through and you control connections at that level. Pretty sure that could be very popular - router tech is very stagnated imo.

That’s why I have a PiHole.
