## 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)
- "look for established, globally distributed enterprise security providers (such as Cloudflare, Akamai, Imperva, Radware, AWS Shield, or Google Cloud Armor)" (Gemini 3.5 Flash, negative prompt, first choice)

## What the models said about Imperva DDoS Protection

- "Custom (high) | Enterprise-focused sales model" (DeepSeek V4 Flash, budget prompt, hard negative)
- "Imperva (strong L7 + network protection)—great if you need custom SLAs, but pricier and more complex for mid-sized setups." (Grok 4.1 Fast, paraphrase prompt, soft negative)
- "though pricing is likely higher than the options above" (GLM 4.7 FlashX, budget prompt, soft negative)
- "Cloudflare or Imperva Incapsula are the most frequently cited cost-effective starting points" (Muse Glimmer 30B, direct prompt, first choice)
- "Offers a powerful Data Security Platform. It is slightly more complex to configure than Cloudflare but offers granular control" (Qwen 3.7 Flash, direct prompt, alternative)
- "Imperva, Radware, NETSCOUT Arbor Cloud, and F5 Silverline are often selected when organizations want hybrid architectures" (Perplexity Sonar, comparative prompt, alternative)
