This project is known for its developers' insistence on open source code, good documentation, code correctness, and security. This project has a strict policy on licensing, preferring the ISC license and other variations of the simplified BSD license. Many of the security features are optional or not in other system operations. Developers often audit source code for software bugs and security holes. De Raadt coordinated this project from his home in Calgary, Alberta, Canada. The logo and mascot are puffer fish named Puffy.
