Mission statement

Make OPNsense the most widely used open source security platform.

So why did we fork pfSense?

OPNsense® is a fork of pfSense® that in its turn has been forked from m0n0wall®. We thank all those that contributed to these projects.
These are our reasons for forking and creating OPNsense:

OPNsense makes building the software easy and provides the tools to do so.
The OPNsense team has a clear idea on how proper software should be written. The complete codebase is being reviewed and gets a huge cleanup.
This leads to a codebase that can be used by developers and is maintainable.

OPNsense wants to build a thriving community that gives and shares.
Sources, tools and all you need to build it or verify the software.
OPNsense is and will be available with the simple 2-clause BSD license.
We believe an open source project should provide the sources and the tools to build it.

OPNsense core team

The international core team currently consists of three people.
The core team determines the project roadmap, it’s technical foundation and coding guidelines. So who are the people making OPNsense happen?

Franco Fichtner

Ad Schellevis
Consultant, developer and engineer with a focus on quality. First time right.
