Movement

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

By model

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.

“Internet-scale discovery, comprehensive scanning, strong API | Good mid-market fit, ~$25K+/year” DeepSeek V4 Flash · ASM · scale prompt · first choice

“the best practical choice is usually Intruder or Censys” GPT-5.4 mini · ASM · budget prompt · first choice

“If you want a more budget-friendly / easier-to-adopt option, I'd put Censys ASM very high on the shortlist.” GPT-5.4 mini · ASM · paraphrase prompt · alternative

“Best-in-class discovery accuracy and internet intelligence depth; strong API; free tier for research.” DeepSeek V4 Flash · ASM · comparative 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.

“Platforms to Approach with Caution ... often priced out of reach for mid-market budgets” Gemini 3.5 Flash · ASM · direct prompt · hard negative

“Censys is explicitly described as best-in-class for internet scanning, but with no validation, making it a strong data layer rather than a standalone ASM program.” Perplexity Sonar · ASM · negative prompt · soft negative

“Frequently cited as a best-in-class *data layer* for discovery, but reviews often note that it offers no validation... dangerous as a standalone solution.” GLM 4.7 FlashX · ASM · negative prompt · soft negative

“it does not offer validation of exposures... this makes it more suitable as a data layer or for discovery rather than a standalone ASM solution” Mistral Small · ASM · negative prompt · soft negative

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 Censys ASM. 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 53 of the 69 answers that named Censys ASM 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 Censys ASM'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 Censys ASM, 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 censys.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.
