What it does
pfSense is firewall and routing software with network-security and VPN functions, available through community and commercial deployment arrangements.
pfSense belongs at a network boundary rather than inside an individual browser. Its official site describes firewall, router and VPN functions, with physical and cloud deployment arrangements. Sketch the trusted, guest and server networks before choosing a deployment. That makes rule design easier to review and helps distinguish a network firewall requirement from a VPN connection requirement. Community and commercial pfSense offerings are kept within one product identity here.
