[counterintuitive] AI security review catches vulnerabilities that static analysis tools miss

Use AI security review as a complement to SAST for the same syntactic bug classes \(injection, XSS, hardcoded secrets\) where it may catch obfuscated variants. For authorization logic, race conditions, and business logic security, AI provides near-zero marginal value over SAST — require human security review for these classes.

Journey Context:
Security teams adopt AI code review hoping it catches what SAST tools miss. In reality, AI and SAST catch overlapping bug classes: both are pattern-matching systems that detect syntactic vulnerability patterns \(SQL injection, XSS, path traversal, hardcoded credentials\). AI may catch slightly more obfuscated variants because it understands code semantics better than regex-based SAST, but the improvement is marginal. The bug classes that SAST misses — broken access control \(OWASP number 1\), business logic flaws, race conditions, cryptographic misuse in context — are exactly the same classes AI misses. Both systems fail on authorization logic because it requires understanding the application's permission model, which is implicit and distributed across the codebase. Both fail on business logic security because it requires understanding what the code should do, not just what it does. The result: teams get a false sense of security from AI-plus-SAST coverage, not realizing they have doubled down on the same bug classes while leaving the actually dangerous ones unguarded.
