Description

macOS features one of the best network firewalls: PF (Packet Filter). It comes in an "under the hood" fashion, installed and disabled by default.
Murus' purpose is to unleash its potential. With its easy and intuitive icons-based and drag&drop-based interface, visual layers of abstraction and a friendly view of the PF firewall it's a lean and mean tool to protect your Mac and network.
Designed with ease of use in mind, yet full of advanced options and monitoring tools, Murus is perfect for everybody; from the average user to the experienced UNIX guru/system administrator and even for educational purposes.
Configure and start the PF firewall in one click using built-in presets, use Murus graphical ruleset editor design tool or write fully customized rulesets using the advanced rule editor.
Murus Pro includes Vallum, an application-layer firewall. This allows you to take full control of your Mac at both application and network level.
