## What the models said about SonarQube

- "Noisiest out-of-box (40-60%+ FPs on Java/TS; OWASP F1-score ~27% in some evals)... avoid for security-only if you can't invest in config" (Grok 4.1 Fast, negative prompt, hard negative)
- "Tools originally designed for *general code quality* (like SpotBugs, SonarQube's default rules) are often very weak at security-specific detection" (DeepSeek V4 Flash, negative prompt, soft negative)
- "A code-quality scanner treated as comprehensive security coverage... verify the actual security rules for your languages, frameworks, and edition." (GPT-6 Luna, negative prompt, soft negative)
- "The best SAST tool for a company with a limited budget is Semgrep's free tier, SonarQube Community, Snyk Code's Team plan, or DeepSource." (Llama 4 Maverick, budget prompt, first choice)
- "The Best All-Around Choice: SonarQube (by SonarSource) This is the most balanced recommendation for most mid-sized companies." (Qwen 3.7 Flash, paraphrase prompt, first choice)
- "For many mid-sized B2B companies, SonarQube or Snyk offer good balance between cost, ease of use, and effectiveness." (Claude Haiku 4.5, paraphrase prompt, first choice)

## What the models said about Checkmarx One

- "What I'd Avoid for Mid-Market: Checkmarx and Veracode are powerful but typically start at $60K–$100K+/year" (Kimi K2, paraphrase prompt, hard negative)
- "be especially cautious with legacy configurations of Checkmarx, Fortify/OpenText, and SonarQube for security use cases unless they are heavily tuned" (Muse Glimmer 30B, negative prompt, soft negative)
- "Legacy enterprise | Checkmarx, Veracode, Fortify | Deep compliance... unless you have specific compliance requirements that mandate legacy tools" (Kimi K2, scale prompt, soft negative)
- "Checkmarx One (Gartner/Forrester Leader): Enterprise-grade with deep dataflow/taint analysis... Checkmarx for banks" (Grok 4.1 Fast, comparative prompt, first choice)
- "an enterprise-grade scanner (like Checkmarx or Fortify) for nightly full-scan reports and compliance auditing." (Qwen 3.7 Flash, comparative prompt, first choice)
- "Gartner Magic Quadrant Leader for 7 consecutive years... Best For: Large enterprises, portfolio-level governance" (Kimi K2, comparative prompt, first choice)
