Great OSX App for visibility on your network activity. iStat Menus is a great alternative. For Windows users, Glasswire was released today.

Love the name!

Little Snitch is awesome. Highly recommend. It's surprising how many apps call home

One of my absolute favorite OS X utilities.

Probably the funniest (and most memorable) product name I've ever heard.

It's an outbound firewall that is able to block on a connection level. Alternatives are: Mac OS X' built-in firewall or TCPBlock. I don't see how iStat Menus is an alternative to Little Snitch?
