TCPBlock Alternatives

    TCPBlock is described as 'lightweight and fast outbound firewall for Mac OS X 10.5 or later developed by Very simply to set up and use. And best of all it doesn't nag' and is an app in the Security & Privacy category. There are eight alternatives to TCPBlock for a variety of platforms, including Mac, Windows, Linux, VirtualBox and VMware vSphere Hypervisor. The best alternative is Little Snitch. It's not free, so if you're looking for a free alternative, you could try TinyWall or Gufw. Other great apps like TCPBlock are Radio Silence (Paid), TripMode (Paid), Hands Off! (Paid) and CacheGuard-OS (Paid).
