OPNsense started as a fork of pfSense® and m0n0wall in 2014. The project has evolved while retaining familiar aspects of m0n0wall and pfSense. A strong focus on security and code quality drives the project’s development.
OPNsense offers weekly security updates with small increments to react to new emerging threats within a fashionable time. A fixed release cycle of 2 major releases each year allows businesses to plan upgrades. For each major release, a roadmap is put in place to guide development and set clear goals.
