Back in 2006 we developed WaterRoof, a free and open source ipfw firewall front end for Mac OS X. When Apple abandoned ipfw and switched to pf we developed IceFloor, the first pf front end for OS X. Now we strive to provide great applications for the Mac and iOS community and we started with the Murus family of products. Murus wants to redefine the approach to network firewall, giving the user unparalleled easy of use and power. We are going to add new features and new companion apps, as well as improve our support services. Stay tuned!
