Static Application Security Testing (SAST) is a crucial component of an Application Security program, analyzing source code to detect syntax errors, bugs, and vulnerabilities. SAST tools should be easy to deploy, integrate with your project, support the languages and frameworks you use, provide real-time scans, and deliver actionable information for developers to prioritize and fix issues. Customizable solutions like Semgrep allow for better adaptation across different projects and teams. Automated, frequent, and comprehensive SAST scans ensure maximum protection throughout the entire Software Development Lifecycle (SDLC).
