OPNsense is an open source, FreeBSD-based firewall and routing software developed by Deciso, a company in the Netherlands that makes hardware and sells support packages for OPNsense.

Launched in 2015, it is a fork of pfSense, which in turn was forked from m0n0wall built on FreeBSD. When m0n0wall closed down in February 2015 its creator, Manuel Kasper, referred its developer community to OPNsense.
