Short description of this page.
Although OPNsense can be virtualized like an ordinary operating system, a `real firewall´ should always run on physical hardware, as network performance makes the difference. See below our hardware recommendation for OPNsense.
OPNsense is an open source, FreeBSD based firewall and routing platform. It includes most of the features available in expensive commercial firewalls. OPNsense is a fork of the well-known open source firewall pfSense which split off in 2015 due to licensing disagreements.
The development is free and open, based on the BSD license, that allows everyone to use, modify, close, and commercially distribute.
OPNsense is FreeBSD-based firewall and routing software developed by Deciso, a Dutch company. The distribution is very popular in Europe and widespread.
