Movement

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

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Tenable is widely regarded as the market pioneer... Choose Tenable or Qualys if you have a massive, hybrid, or complex physical corporate network” Gemini 3.5 Flash · Vuln management · comparative prompt · first choice
“Best for broad enterprise coverage and exposure management; it uses agent + agentless + cloud-native scanning” Perplexity Sonar · Vuln management · comparative prompt · first choice
“For most enterprises, Tenable or Qualys are the top choices depending on your deployment preferences.” GLM 4.7 FlashX · Vuln management · comparative prompt · first choice
“Tenable positioned highest overall in Gartner for broad attack surface coverage and execution” Grok 4.1 Fast · Vuln management · comparative 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.

“You may see vendors (like older versions of Tenable) marketing "Unified" solutions... Why to Avoid: ... these legacy stacks are often too heavy and slow.” GLM 4.7 FlashX · ASM · negative prompt · hard negative
“Many modern security vendors (like Tenable or Qualys) sell compliance add-ons... When used as a standalone GRC platform, they often lack the workflows for policy management” Qwen 3.7 Flash · GRC · negative prompt · soft negative
“powerful, highly accurate, and standard for compliance, though they can sometimes feel overly complex for smaller teams” Gemini 3.5 Flash · Vuln management · scale prompt · soft negative
“competitive concerns raised by Qualys about Tenable's platform (fragmented portals, slower zero-day remediation)” MiniMax M2.5 · Vuln management · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Tenable. 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 70 of the 98 answers that named Tenable and are not a share of its labels.

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 Tenable'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 Tenable, 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 tenable.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.
