DoorStop X Security Suite puts a friendlier front end on OS X’s built-in firewall, making it an excellent solution for users who like the idea of using that built-in firewall but would like to be able to configure it more completely without resorting to the Terminal.

The question is, are you willing to pay $80 for such access? I think it’s definitely worth the ducats. But if you’re on a tighter budget, you can opt to purchase the firewall alone, without the rest of the Suite, for $49.
