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.

“opt for "automated security validation" or highly-automated BAS vendors (e.g., Cymulate, Pentera, Picus, or Horizon3)” Gemini 3.5 Flash · BAS · scale prompt · first choice

“often cited as a strong BAS option for startups and small businesses due to its 30-day free trial and affordable pricing options” Claude Haiku 4.5 · BAS · budget prompt · alternative

“A pioneer in autonomous testing. Their agentless *NodeZero* platform executes full-scale, safe-to-run exploit chains” Gemini 3.5 Flash · PTaaS · comparative prompt · alternative

“If you want to replace expensive manual penetration tests ... choose Horizon3.ai NodeZero” Gemini 3.5 Flash · BAS · 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.

“These use AI to hack you automatically. It's cheap and constant, but it may lack the creativity of a human finding a complex logic flaw.” Qwen 3.7 Flash · PTaaS · comparative prompt · soft negative

“more polished but exceed "limited budget" ... Avoid them unless you have funding.” Grok 4.20 · BAS · budget prompt · soft negative
