What the models said for it

Verbatim evidence the judge attached to positive labels.

“1. Nightfall AI – Best for Cloud-First SaaS Companies ... Fastest deployment, minimal security staff | Nightfall AI” Kimi K2 · DLP · direct prompt · first choice

“modern data-lineage and browser-focused DLP tools (e.g., Cyberhaven, Nightfall, Strac, or Next DLP)” Gemini 3.5 Flash · DLP · negative prompt · first choice

“Choose Nightfall AI if you are 100% cloud-native, operate heavily on Slack, Jira, and GitHub” Gemini 3.5 Flash · DLP · direct prompt · first choice

“For a limited budget, start with a free plan from Nightfall, Google Cloud DLP, or Box Shield.” Mistral Small · DLP · budget 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.

No model argued against it.

What carried it into the answer

The sites and pages cited by the answers that named Nightfall AI. 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 67 of the 77 answers that named Nightfall AI 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 Nightfall AI'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 Nightfall AI, 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 nightfall.ai 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.
