DoorStop X is designed to work with our Who's There? Firewall Advisor.

Note for Mavericks users: If you have installed the DoorStop X Firewall (version 2.4) on Mac OS X 10.7 Lion or 10.8 Mountain Lion and then upgraded your Mac to Mavericks, the firewall should continue to run fine and provide the same levels of protection and logging as previously. Mavericks, however, includes security changes that make it difficult to install a new copy of the DoorStop X Firewall onto that operating system, so we are not recommending purchase of the DoorStop X Firewall for new Mavericks systems.

Limitations: Fully-functional 30-day trial.

Requirements:
OS X 10.5.8 - 10.9
