Little Snitch 3 your network connection monitor
I have a couple of applications that I always install on a new Mac. It’s the first I do after the initial setup is completed. They are the essential software I need to have installed to be productive and secure. Little Snitch by Objective Development is one of them. I’ve been using it for more than ten years now, and I wouldn’t dream of running a Mac without it installed. What Little Snitch 3 essentially does is monitor all outgoing traffic from your open applications and processes and gives you the ability to allow or deny that traffic. This is a great way of seeing what kind of information is sent from applications without your knowledge or consent. And it’s a great way of stopping traffic that “Phones home” without your explicit permission. When an application tries to send out something over the network, it gets intercepted by Little Snitch and you can then allow or deny the connection, either temporary or permanently via the dialog box that appears. So Little Snitch is always there, protecting your privacy.
