 OPNsense was originally developed as a fork of [pfSense](https://en.wikipedia.org/wiki/PfSense), and both projects are noted for being free and reliable firewall distributions which offer features often only found in expensive commercial firewalls. Launched in 2015, the developers of OPNsense [cited](https://docs.opnsense.org/history/thefork.html) a number of security and code-quality issues with pfSense which they felt necessitated a fork of the project, as well as concerns about Netgate's majority acquisition of pfSense and the future direction of the pfSense project.

+**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.

If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress.
