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.

“I'd suggest starting with either Microsoft Sentinel (if already in the Microsoft ecosystem) or Sumo Logic (if you want vendor neutrality)” Claude Haiku 4.5 · SIEM · paraphrase prompt · first choice
“Is primarily a Microsoft/Azure shop | Microsoft Sentinel | Seamless out-of-the-box ingestion, KQL query language, and fast deployment.” Gemini 3.5 Flash · SIEM · comparative prompt · first choice
“Microsoft Sentinel — unbeatable value if you're a Microsoft shop; pay-as-you-go pricing; strong detection content; built-in UEBA and SOAR.” DeepSeek V4 Flash · SIEM · scale prompt · first choice
“If you're in Microsoft world (common for B2B): Go with Sentinel—cost-effective, quick value, scales well without huge teams.” Grok 4.20 · SIEM · direct 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.

“Why to be cautious: Vendor Ecosystem Dependence... difficult, confusing, and often suboptimal if your infrastructure is primarily AWS, Google Cloud, or Linux-based” Qwen 3.7 Flash · SIEM · negative prompt · soft negative
“Sentinel is incredibly powerful. However, do not buy it to manage alone unless you have dedicated KQL (Kusto Query Language) expertise.” Gemini 3.5 Flash · SIEM · scale prompt · soft negative
“Microsoft Sentinel's billing, for example, depends on ingestion tiers, retention, and separate infrastructure charges in some cases” GPT-5.4 mini · SIEM · negative prompt · soft negative
“Microsoft Sentinel, if you're not invested in Azure or haven't modeled the full bill: Pricing depends on data volume and tier” GPT-6 Luna · SIEM · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Microsoft Sentinel. 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 359 of the 389 answers that named Microsoft Sentinel 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 Sentinel'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 Sentinel, 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 Sentinel by email, built from the raw record of the edition. It shows:

  • where Microsoft Sentinel 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 Sentinel, 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 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.
