By framing
What the models said for it
Verbatim evidence the judge attached to positive labels.
“Pfsense and OPNsense are excellent free firewall options that provide robust access control capabilities without licensing costs.” Claude Haiku 4.5 · NAC · budget prompt · first choice
“Choose OPNsense + Zenarmor if you have an IT person on hand” Gemini 3.5 Flash · Firewalls · budget prompt · alternative
And against it
Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.
“they usually lack the built‑in advanced threat‑intel, seamless updates, and support that commercial NGFWs provide” MiniMax M2.5 · Firewalls · budget prompt · soft negative
“can be free but require hardware investment and technical expertise” GLM 4.7 FlashX · Firewalls · budget prompt · soft negative

How it is countedHide how it is counted
Every page opnsense.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. Read September 29, 2026.

Claim this page
Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when OPNsense's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as OPNsense, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
What a new claim receivesHide what a new claim receives
A new claim receives the current edition's vendor brief for OPNsense by email, built from the raw record of the edition. It shows:
- where OPNsense is named, by buyer and by framing, and which cells hold its first choices;
- the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
- its vocabulary against the segment leader's, and the pages the models cited;
- who was chosen in the answers that did not name OPNsense, and every reason the record gives;
- a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
- one page of published figures cleared to show a buyer.
