## What the models said for it

- "Cloudflare WAF and AWS WAF are recommended for most clients because they have low false‑positive rates" (GLM 4.7 FlashX, WAF)
- "I'd suggest evaluating Cloudflare WAF or AWS WAF (if using AWS) as starting points" (Claude Haiku 4.5, WAF)
- "Fastest time-to-value | Cloudflare or AWS WAF" (Kimi K2, WAF)
- "If you're already heavily invested in AWS or need on‑premises hardware, AWS WAF or F5 BIG‑IP become compelling alternatives" (GLM 4.7 FlashX, WAF)

## And against it

- "Out of the box, AWS WAF is essentially a blank canvas... It requires deep cloud-engineering expertise to manage, meaning high operational overhead" (Gemini 3.5 Flash, WAF)
- "Be cautious of cloud WAFs unless you configure specific rules to block or inspect oversize/padded request bodies." (Gemini 3.5 Flash, WAF)
- "Complicated rules hard to maintain; support delays; frequent evasions (e.g., parsing bugs)." (Grok 4.1 Fast, WAF)
- "AWS WAF is very granular, which leads to high operational overhead." (Qwen 3.7 Flash, WAF)
