## What the models said about Cloudflare

- "Cloudflare's lower tiers work well for basic volumetric attacks, but for sophisticated application-layer attacks, you will often need to upgrade to Enterprise or manually tune complex rate-limiting rules." (Claude Haiku 4.5, negative prompt, soft negative)
- "Over‑protective bot protection that flags legitimate users... When to be cautious: If your organization cannot tolerate even brief outages" (GLM 4.7 FlashX, negative prompt, soft negative)

- "Options to Avoid on a Limited Budget ... $3,000/month" (DeepSeek V4 Flash, budget prompt, hard negative)
- "AWS Shield Standard protects only when used with AWS edge services like CloudFront and Route 53, and Shield Advanced is needed for stronger cost protection" (Perplexity Sonar, negative prompt, soft negative)
- "Cloudflare and AWS Shield Advanced are the top choices due to their balance of cost, ease of use, and comprehensive protection" (Mistral Small, direct prompt, first choice)
