During the integration phase of a high-velocity DevSecOps pipeline, developers frequently commit code that contains complex, non-linear logic flaws…

Traditional rule-based SAST tools struggle with semantic and logical flaws because they lack contextual understanding of the code. AI-powered SAST, particularly solutions leveraging Large Language Models (LLMs), can analyze code with a deeper understanding of its logic, intent, and context. This allows them to identify complex, non-linear vulnerabilities that evade signature-based detection. Deploying an LLM for automated code review directly addresses the need to find nuanced flaws in a high-velocity DevSecOps pipeline, providing a scalable and more intelligent alternative to manual reviews or legacy tools.

A. This is a runtime protection measure for user input, not a static analysis technique for identifying logic flaws within the source code itself.

B. Manual reviews are not an automated AI-driven solution and cannot keep pace with a high-velocity DevSecOps pipeline, creating significant bottlenecks.

C. The question explicitly states that traditional rule-based scanners are failing; updating signatures does not change their fundamental inability to detect complex logic flaws.
