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.

“In 2026 evaluations Palo Alto Cortex XDR scores highest, with CrowdStrike close behind” Muse Glimmer 30B · XDR · comparative prompt · first choice

“If you want governed autonomy: Palo Alto” GPT-5.4 mini · AI SOC agents · comparative prompt · first choice

“If you are standardizing on a giant ecosystem (like Palo Alto XSIAM or Microsoft Sentinel/Azure), using their highly integrated, native automation tools is often the path of least resistance.” Gemini 3.5 Flash · SOAR · negative prompt · alternative

“Modern SOCs wanting a unified, opinionated all-in-one platform with lower total cost of analytics and faster MTTR vs traditional SIEMs” Muse Glimmer 30B · SIEM · comparative 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.

What carried it into the answer

The sites and pages cited by the answers that named Palo Alto Networks Cortex XSIAM. 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 95 of the 96 answers that named Palo Alto Networks Cortex XSIAM and are not a share of its labels.
