The demand for automated security analysis techniques, specifically static application security testing (SAST), is steadily rising. Assessing the effectiveness of SAST tools is crucial for evaluating current techniques and inspiring future technical advancements. Regrettably, recent research suggests that existing benchmarks used for evaluation often fail to meet the industry’s needs, significantly impeding the adoption of SASTs in real-world scenarios. This paper presents a qualitative study to bridge this gap. We investigate why industrial professionals utilize SAST benchmarks, identify barriers to their usage, and explore potential improvements for existing benchmarks. Specifically, we conducted in-depth, semi-structured interviews with twenty industrial professionals possessing diverse field experience and backgrounds in security and product development. As the first comprehensive investigation of SAST evaluation from an industrial perspective, our findings would break down the barriers between academia and industry, providing valuable inspiration for designing better benchmarks and promoting new advances in SAST evaluation.
