## What the models said about OWASP ZAP

- "The Verdict: Avoid for CI/CD pipelines. Use only if you have dedicated in-house pentesters." (GLM 4.7 FlashX, negative prompt, hard negative)
- "High false positive rates require significant manual tuning and expertise... Avoid if: You're new to security testing or need low-maintenance automation." (Grok 4.1 Fast, negative prompt, soft negative)
- "While OWASP ZAP is excellent and free, mid-sized B2B companies typically: Lack dedicated security teams to tune and manage false positives" (Kimi K2, paraphrase prompt, soft negative)
- "For most small to medium-sized companies just starting with DAST, OWASP ZAP is typically the best choice due to its zero cost, robust features, and strong community support." (Claude Haiku 4.5, budget prompt, first choice)
- "the best DAST tool is usually OWASP ZAP because it is free, open-source, extensible, and widely recommended as the default starting point" (Perplexity Sonar, budget prompt, first choice)
- "OWASP ZAP (Zed Attack Proxy) is widely considered the best Dynamic Application Security Testing (DAST) tool available." (Qwen 3.7 Flash, budget prompt, first choice)

## What the models said about StackHawk

- "tools like StackHawk are built on ZAP, but they're not the cheapest option for a tight budget" (GPT-5.4 mini, budget prompt, soft negative)
- "For most mid-market B2B companies, StackHawk offers the best balance of features, pricing, and developer experience." (GLM 4.7 FlashX, direct prompt, first choice)
