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.
“Stellar Cyber Open XDR is repeatedly highlighted for mid-market teams needing enterprise capabilities without vendor lock-in” Muse Glimmer 30B · XDR · direct prompt · first choice
“such as Sophos Intercept X or Stellar Cyber Open XDR. These platforms are designed for mid-market teams” Llama 4 Maverick · XDR · direct prompt · first choice
“Stellar Cyber is recommended for enterprises with limited staff and budget” Claude Haiku 4.5 · NDR · budget prompt · first choice
“Leads the market with true agentic AI architecture designed specifically for mid-market companies with lean security teams” Claude Haiku 4.5 · AI SOC agents · direct 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.
“Stellar Cyber is less specialized in NDR depth” Perplexity Sonar · NDR · negative prompt · soft negative

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.
What carried it into the answer
The sites and pages cited by the answers that named Stellar Cyber Open XDR. 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 66 of the 66 answers that named Stellar Cyber Open XDR and are not a share of its labels.

How it is countedHide how it is counted
Every page stellarcyber.ai 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. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read September 29, 2026.
