Deciso has just launched their own fork of pfSense, an open source firewall, which is also based on FreeBSD.
OPNsense combines the best of open source and closed source firewalls. It brings the rich feature set of commercial offerings with the benefits of open and verifiable sources combined with a simple BSD license. This makes OPNsense the platform of choice for users, developers and commercial partners.
Companies that want to use OPNsense to create a branded version, extend its features, or even create a fork and build upon the same codebase are allowed to do so under the 2-clause BSD license.
The large feature set OPNsense includes several high-end features like load balancing, high availability and captive portal. The modern and easy-to-use Bootstrap based user interface makes configuring and managing the firewall a comfortable task for administrators. And maybe the best part; All sources and build tools are freely available without special clauses and without licensing costs.
