I was using LittleSnitch years ago and installed it again yesterday. LittleSnitch is like a neat little firewall (basically it’s a socket filter for macos) – but it also now has this neat map in a great design showing at a glance, where your data is going to geographically:
Its funny to see, how some apps are even sending data home where they were not supposed to. I don’t get why deepl, my favourite AI translator, hosts its data in the US, wheras its just a kilometer away from my office in cologne. They should not.
LittleSnitch comes in a „silent mode“ which by default allows all traffic, but sends you a notification as soon as a „new“ connection is established – and you can then decide if you want to allow or forbid that.
