How Replit Secures AI-Generated Code [white paper]

AI-generated code introduces new security challenges, questioning if AI-driven security scans alone are adequate. Research comparing AI-only scans with hybrid approaches found that AI-only methods are non-deterministic and can miss critical issues like dependency vulnerabilities. Functionally identical code can receive different security assessments based on minor syntactic changes or prompt phrasing. The conclusion is that a hybrid architecture, combining deterministic static analysis with LLM-powered reasoning, is essential for comprehensive security.
