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 Bundle includes Vallum, an application-layer firewall. This allows you to take full control of your Mac at both application and network level.

Share your Internet connection and define per-client access limits and accounting, export LAN services to the Internet with port forwarding. Everything is done simply using icons, checkboxes, buttons. And everything is based only on features and tools already built into macOS.
A firewall is not magic. You are going to protect your Mac, and you are going to do it using PF, the macOS firewall. Use Murus to learn how PF works, using the three layers of abstraction. These layers represent the firewall configuration using icons or using simplified, commented and visually enriched rules, or using a runtime table-based rules browser. Protecting your Mac is not the only purpose of Murus. It is also a learning tool. We include documentation for both Murus and PF Log Reader, and a generic macOS PF manual. You will learn how to handle PF and you will be able to create and manage your own hand-made rulesets.
