pfSense is an open-source firewall and router operating system based on FreeBSD, developed and maintained by Netgate, providing stateful firewall, routing, VPN (IPsec, OpenVPN, WireGuard), captive portal, traffic shaping, and IDS/IPS capabilities for home and enterprise networks. It is available as pfSense Community Edition (CE) and pfSense Plus, both managed via a web UI. The unofficial pfSense-pkg-RESTAPI package adds a REST and GraphQL API with 200+ endpoints under /api/v2 for automating firewall management, authenticated via local users, API keys, or JWT.
