SOME LEGAL GUIDELINES

The OPNsense project aims to be a project that is friendly for users, developers and partners. In this world with trademarks en copyright it is best to “keep things as simple as possible, but not simpler”. Below we pointed out the Licensing and Trademark rules we use.

Open Source Initiative

Copyright License

OPNsense is licensed under an Open Source Initiative approved license.

We like the BSD license, a simple two clause license that gives freedom to the audience we want to serve.  It basically gives you the right to do whatever you want to do with the code, even fork it and take it from there.
