October 2026 Edition. Every number here is derived from the raw labels under vendor table v2026-10.8, every buyer segment counted.

Standing

5 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. Prompt Security was named 5 times in AI security, where SentinelOne Singularity led with 11%. The labels and the evidence are below, counted exactly.

Movement

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

By model

How each model treated Prompt Security across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Prompt Security (SentinelOne) and Akto are top recommendations due to their comprehensive coverage” Mistral Small · AI security · paraphrase prompt · first choice

“Govern workforce shadow AI – Prompt Security/SentinelOne or Check Point Workforce AI Security.” Muse Glimmer 30B · AI security · comparative prompt · alternative

“look at Harmonic Security or Prompt Security” Gemini 3.5 Flash · AI security · comparative prompt · alternative

“Alternative for SentinelOne Shops: Prompt Security” Gemini 3.5 Flash · AI security · direct 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.

“overkill if you don't need full endpoint security” Kimi K2 · AI security · paraphrase prompt · hard negative

How it is countedHide how it is counted

Every page prompt.security 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. Read October 5, 2026.

Names read as Prompt Security

its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name Prompt Security, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.
