IPFire vs OPNsense
Side-by-side comparison of features, pricing, ratings, and alternatives.
IPFire is an open-source Linux distribution built specifically to run as a firewall and network security gateway. It provides stateful packet inspection, network segmentation with DMZ and guest zones, and a web-based console for managing rules and monitoring traffic in real time, running on ordinary commodity hardware or as a virtual appliance. Beyond basic filtering, IPFire integrates Suricata-based intrusion detection/prevention, WireGuard, OpenVPN, and IPsec VPN support, a community-maintained domain blocklist, and an IP geolocation database for location-based rules. It is free and open-source with no paywalled features, while Core Updates ship regularly and commercial appliances and support are available separately.
OPNsense is an open-source firewall and routing platform built on FreeBSD, offering a stateful firewall for IPv4/IPv6, multi-WAN load balancing and failover, and hardware failover via the CARP protocol. It bundles multiple VPN options (IPsec, OpenVPN, WireGuard, Tinc), an intrusion prevention system powered by Suricata, and NetFlow-based traffic reporting, all managed through a web GUI. The core platform is free under a permissive BSD/MIT license and can run on anything from a fanless mini-PC to a rack appliance, including official OVA images for virtualization. A paid Business Edition adds a Web Application Firewall, extended threat-intelligence blocklists, centralized fleet management (OPNcentral), and training/e-book resources for organizations that need vendor-backed support.
