Finally answers which AI security scanner actually works — with cost data included.
Strengths
- •Standardized F3 strict scoring enables apples-to-apples comparison across 24 scanners
- •Cost-per-scan metrics reveal expensive underperformers like GPT-5.5 at $66
- •Real vulnerability dataset with 26 repos provides meaningful evaluation ground truth
Weaknesses
- •Benchmark relevance depends on vulnerability dataset staying current with new exploit patterns
- •Enterprise scanners may optimize for this specific benchmark rather than real-world performance
