    What the Ledger says

    OPNsense earns its credibility score the plain way: eleven years of majors on the dates the roadmap named, with every feature in the free edition and a point release whenever a fix is ready. Capability sits in the solid band across the board because the project keeps rebuilding its own pages onto the API rather than adding enterprise layers, so central management, VRFs, TLS inspection and ARM are missing while VPN, DHCP and firewall basics are complete. The commercial and lock-in scores are among the lowest in the Ledger because nothing is gated and the configuration is one XML file. A buyer should check how the six-month series change fits their change window, since the previous series stops receiving fixes as soon as the next one ships.

    OPNsense has no AI in its threat engine, no assistant in the console and no AI announcements; Suricata signatures and third-party rulesets do the detection. Its REST API is broad enough for agents to drive, which is why community MCP servers appeared in 2025 without any Deciso involvement.

    Purchase constraints0.5
    Community Edition free with every feature; Business Edition per installation in any quantity; a cluster needs two subscriptions
    Channel and access1
    Open download and open security fixes for everyone; Business repository lags the Community Edition by design; partner terms unpublished
    Owner stability1
    Small private Dutch company, founder-led, no acquisition found; size is the dependency
    Cost of staying supported1.5
    Updates are free, but staying patched means moving to a new series every six months; no LTS to stay on

    Technical lock-in(lower is better)

    Formats1
    One XML configuration file (config.xml) with documented backup and restore; plugins push backups to Git, Nextcloud, Google Drive and SFTP
    Export path1.5
    No converter to or from other firewalls; pfSense XML is not directly compatible; rules rebuilt by hand or through the API
    Stack coupling0
    Any storage, any switch; nothing beyond the host
    Hardware / cloud coupling0.5
    Any x86-64 machine or hypervisor, fully offline; no ARM build
    Skills and tooling coupling1
    FreeBSD and pf skills, less common than Linux; open REST API

    Release credibility

    Cadence5
    Two majors a year on fixed dates since 15.1 (2015-01-05); the roadmap table shows every major delivered on its date; point releases every one to three weeks

    Public roadmap page with planned items per release, open GitHub repositories and issue tracker; no support windows or end-of-life dates published
    Say-do4
    Roadmap items for 23.1 to 26.7 shipped in the named release; OpenVPN DCO stayed experimental from 24.7 with no GA found; 27.1 items pending
    Velocity3.5
    Each release rewrites several pages onto the MVC API and brings one or two capabilities (Kea HA, Suricata 8 inline, Dnsmasq DHCP); fewer new features than migrations
    Lifecycle stability3
    Six-month cycle with in-place upgrades and clean deprecation notices; the previous series stops receiving fixes at once; PPTP, L2TP and IKEv1 removal planned for 27.1
