After more than three years of development we are proud to introduce the next generation of our personal application firewall with loads of new features for an even smoother and more enjoyable user experience.
Upgrades from Little Snitch 3 are available for a reduced price.
If you download and install Little Snitch 4 it will run in demo mode until you purchase an upgrade license. The demo mode provides the same protection and functionality as the licensed mode. It runs for three hours, and can be restarted as often as you like. The Network Monitor expires after 30 days.
