Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“If you want the absolute lowest cost and have internal sysadmin skills: go with ModSecurity (free) + OWASP CRS.” MiniMax M2.5 · WAF · budget prompt · first choice
“best-value WAF is usually an open-source stack: ModSecurity + OWASP Core Rule Set (CRS)” GPT-5.4 mini · WAF · budget prompt · first choice
“ModSecurity with OWASP CRS is the de-facto standard free engine.” Muse Glimmer 30B · WAF · budget prompt · first choice
“BunkerWeb or ModSecurity + CRS are excellent choices” GLM 4.7 FlashX · WAF · budget prompt · first choice

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.

“ModSecurity, the classic open-source WAF engine, has reached End-of-Life (EOL).” Gemini 3.5 Flash · WAF · budget prompt · hard negative
“Avoid/Be cautious with: Unpatched ModSecurity v3 versions” Kimi K2 · WAF · negative prompt · hard negative
“A critical vulnerability (CVE-2025-47947) in ModSecurity, a widely deployed open-source WAF, allows attackers to crash systems through denial of service attacks” Claude Haiku 4.5 · WAF · negative prompt · soft negative
“ModSecurity (Open Source) Without Strict Tuning... recent critical vulnerabilities found in ModSecurity versions that allow attackers to bypass path inspection” GLM 4.7 FlashX · WAF · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named ModSecurity. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 49 of the 58 answers that named ModSecurity and are not a share of its labels.

Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

How it is countedHide how it is counted

Every page modsecurity.org 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.

Is this your product?

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 ModSecurity'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 ModSecurity, 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 ModSecurity by email, built from the raw record of the edition. It shows:

  • where ModSecurity 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 ModSecurity, 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.
The subscriber app

A verification link goes to your work email; an address at modsecurity.org is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
