I had great success with NetLimiter. Just like Little Snitch, it's a pain to set up, but it's very revealing.
Also makes you wonder why your Logitech App is talking to all these servers and why it needs to have 4 applications running in the background to... do what exactly?
simplewall[0] is my #1 install on a new machine. Little different, but it'll still alert you to the requests, allow for timers, per application/route rules etc.
A good question. I looked it up. The AlternativeTo site offers a few PC alternatives to Little Snitch:
"Little Snitch is not available for Windows but there are plenty of alternatives that runs on Windows with similar functionality. The best Windows alternative is GlassWire, which is free."
It's not as bad as the vine says, but one thing that drives me crazy, is widgets.exe seems to get a new hash /often/ and I constantly get prompts for it.
It's all the installers that phone home at some point, and video drivers needing access etc. (Wireless displays come at a cost I guess).
sorry, that should have been "Windows version". I wasn't meaning to imply windows itself (although, yeah, from the stories it could be bad too with telemetry crap). i just meant Windows being such a large target for malware and what not
