What Is Snyk Code? Introduction to Snyk's SAST

What is Snyk Code? Snyk Code is Snyk's static application security testing (SAST) product. It scans your first-party source code - the code your team writes, not your dependencies - for security vulnerabilities like SQL injection, cross-site scripting (XSS), path traversal, hardcoded secrets, and dozens of other vulnerability categories. It is one of five products in the Snyk platform, alongside Snyk Open Source (SCA), Snyk Container, Snyk IaC, and Snyk Cloud. What makes Snyk Code different from traditional SAST tools is its detection engine. Most legacy SAST platforms - Checkmarx, Fortify, Veracode - rely primarily on hand-written rules and pattern matching to find vulnerabilities. Snyk Code uses a machine learning engine called DeepCode AI that was trained on millions of open-source code commits. This ML-based approach allows it to understand code semantics, track data flow across files, and detect vulnerability patterns that rule-based tools miss - while maintaining scan times that
