Leveraging the strength of the Mac’s built-in firewall, DoorStop X Security Suite protects your Mac from unwanted access by making the Mac’s firewall easier to config and by making the firewall’s log files useful to everyone from tech-heads to total newbies. (Uh, newbies with one rather small caveat.) Overall DoorStop X Suite is an excellent firewall application.
