## Questions the record answers

**Which endpoint protection platform do AI models name first most often?** Microsoft Defender for Endpoint, in 22% of first choices for a mid-market B2B company in the October 2026 Edition, from 40 labels. The standing is contested: the models did not settle on one product.

**Does the answer change with the size of the company?** Small business: Microsoft Defender for Cloud at 50%. Mid-market: Microsoft Defender for Endpoint at 22%. Enterprise: Microsoft Defender for Endpoint at 44%. Each standing is computed within its segment and never pooled.

**Which framing changes the answer?** The direct, paraphrase, budget and scale framings count toward share. The product named first differs by framing: direct CrowdStrike Falcon; paraphrase Bitdefender GravityZone; comparative CrowdStrike Falcon; budget-constrained Microsoft Defender for Cloud; scale-constrained SentinelOne Singularity Endpoint; negative ESET PROTECT. The table above has the counts.

**How stable is one answer?** Asked again with nothing changed, the models moved their own first choice 63% of the time across the repeat sample; Across the categories asked twice, a leader's share moved 4 points at the median and the index calls a change only above 11 points.

**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 74 answers here cite 1,015 pages; the sites cited most are deel.com, guideflow.com, huntress.com. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
