Movement

This is the first edition on this tier, so no move can be computed for GreyNoise 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 GreyNoise 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.

“Start with free or low-cost tools like Amazon GuardDuty or GreyNoise.” Mistral Small · Threat intel · budget prompt · first choice

“CloudSEK or GreyNoise, depending on whether you want broader external risk monitoring or noise reduction” Perplexity Sonar · Threat intel · budget prompt · alternative

“purchase a low-tier GreyNoise or Feedly for CTI subscription to help filter alerts” Gemini 3.5 Flash · Threat intel · budget prompt · alternative

“Frequently recommended for startups and budget-conscious teams” Kimi K2 · Threat intel · budget 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.

No model argued against it.

A head-to-head page exists where both products are in a category's top three. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named GreyNoise. 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 26 of the 33 answers that named GreyNoise 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 GreyNoise'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 GreyNoise, 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 greynoise.io 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.
