What the models said for it

Verbatim evidence the judge attached to positive labels.

“If your B2B website or customer portal is already behind Cloudflare, their native Client-Side Security ... is often the most logical choice.” Gemini 3.5 Flash · Client-side protection · direct prompt · first choice

“Best Overall & Easiest to Implement: Cloudflare Client-Side Security (Page Shield)” Gemini 3.5 Flash · Client-side protection · paraphrase prompt · first choice

“Choose Cloudflare if you want broad client-side visibility + CSP management.” GPT-5.4 mini · Client-side protection · comparative prompt · first choice

“Cloudflare is a natural shortlist item if you already use its platform” GPT-6 Luna · Client-side protection · 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.

“Free tier doesn't meet PCI 6.4.3; advanced features require paid tiers” DeepSeek V4 Flash · Client-side protection · paraphrase prompt · soft negative
