Outbound firewall for macOS.

OS
Our review

What we like

Shows everything that makes outbound connections. Allows you to control and review what is talking to who. Granular controls for allowing/denying by IP, hostname, process. Knows when binaries change so you can review rules. Can import regularly updating block lists e.g. known malware hosts. Has explainers for common programs so you know what they are.

What we don't like

Very noisy after you first install it - reveals how much is actually making outbound connections! Binary change alerts can be annoying if you’re developing code that compiles.
