Our Paragon Firewall for Mac is one of the first applications, designed with the latest Apple System Extensions technology, represented on WWDC 2019 as a result of NKE’s deprecation announcement. This is also one of the first open-source firewalls available in the Appstore.
Working with our application’s source code can get developers a good idea of how to deal with the new Apple’s framework a well as a good experience of practicing general software security.
