September 2026 Edition. Every number here is derived from the raw labels under vendor table vv2026-09.2, every buyer segment counted.

Standing

3 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. Deloitte was named 3 times in PTaaS, where Cobalt led with 44%. The labels and the evidence are below, counted exactly.

Standing by category

Every category where a model named Deloitte for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

This is the first edition on this tier, so no move can be computed for Deloitte yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Deloitte across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

No positive label carried a quote.

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.

“avoid the "Big 4" firms (Deloitte, KPMG, PwC, EY) as they are too expensive” Qwen 3.7 Flash · PTaaS · budget prompt · hard negative

“The "Big 4" (Deloitte, KPMG, etc.): Usually too expensive and bureaucratic for a routine pentest.” Qwen 3.7 Flash · PTaaS · scale prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Deloitte. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 3 of the 6 answers that named Deloitte and are not a share of its labels.

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 Deloitte'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 Deloitte, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at deloitte.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
