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.

“Offers the broadest range of deployment form factors and has the most extensive OT and IoT device coverage by asset type count and the strongest scalability” Claude Haiku 4.5 · OT/IoT security · direct prompt · first choice

“Claroty and Nozomi are widely regarded as market leaders for broad asset visibility and risk posture.” Gemini 3.5 Flash · OT/IoT security · scale prompt · first choice

“I'd recommend Nozomi Networks (specifically their Guardian platform with Vantage SaaS management)” Grok 4.1 Fast · OT/IoT security · paraphrase prompt · first choice

“Prioritize Gartner/PAC-evaluated natives (Claroty/Nozomi/Dragos) for critical infra.” Grok 4.1 Fast · OT/IoT security · negative 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.

“Avoid if budget is tight: Nozomi Networks” Perplexity Sonar · OT/IoT security · budget prompt · hard negative

“The presence of recent high-severity privilege and authentication issues does not mean the product should be avoided outright, it means deployments must be kept current” Muse Glimmer 30B · OT/IoT security · negative prompt · soft negative

“frequently cost six figures and require dedicated Security Operations Center (SOC) teams—usually out of reach” Gemini 3.5 Flash · OT/IoT security · budget prompt · soft negative

“"don't overbuy for your scale." The platform is expensive and complex” DeepSeek V4 Flash · OT/IoT security · negative prompt · soft negative

How it is countedHide how it is counted

Every page nozominetworks.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read October 5, 2026.
