Movement

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

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.

“Praised as the best value overall for mid-market organizations” Mistral Small · XDR · direct prompt · first choice

“Top Performers: Bitdefender (consistent 99-100%, low TCO)” Grok 4.1 Fast · Endpoint protection · negative prompt · first choice

“Bitdefender - a value pick for mid-market organizations” Llama 4 Maverick · XDR · direct prompt · first choice

“offers detection engines that consistently test at the top, with EDR capability at pricing mid-market organizations can approve” Llama 4 Maverick · XDR · paraphrase 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.

“Cautionary Examples: Vendors like Acronis or Bitdefender... Independent testing occasionally finds gaps between marketing claims and actual performance” Qwen 3.7 Flash · XDR · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Bitdefender. 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 57 of the 58 answers that named Bitdefender 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 Bitdefender'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 Bitdefender, 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 bitdefender.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.
