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.

“The best EDR platform for a company with a limited budget is Microsoft Defender if you hold E5” Llama 4 Maverick · EDR · budget prompt · first choice
“Best budget-friendly default: Microsoft Defender + Security Copilot agents” GPT-5.4 mini · AI SOC agents · budget prompt · first choice
“Offers "Cloud App Governance." It allows you to track which external applications are accessing your corporate data.” Qwen 3.7 Flash · SaaS management · budget prompt · alternative
“Microsoft Defender: Get threat prevention and detection with Microsoft Defender security capabilities.” Muse Glimmer 30B · M365 management · 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.

“solid for basics, no extra cost), but upgrade for EDR/advanced features” Grok 4.20 · Endpoint protection · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Microsoft Defender. 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 52 of the 59 answers that named Microsoft Defender and are not a share of its labels.

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

  • where Microsoft Defender 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 Microsoft Defender, 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.

A verification link goes to your work email; an address at microsoft.com 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.
