Static Application Security Testing (SAST) scans application code for security vulnerabilities automatically. Configure SAST tools like Semgrep, SonarQube, or CodeQL to detect issues across multiple languages, integrate them into CI/CD pipelines, and establish baseline scans and quality gates to catch vulnerabilities before deployment.

Yes. SAST tools embed directly into CI/CD workflows for continuous vulnerability detection on every commit. This Skill provides integration patterns and automation scripts for GitHub Actions, GitLab CI, and other platforms, enabling security gates that block merges when vulnerabilities exceed thresholds.

Semgrep supports multiple languages including Python, JavaScript, Java, Go, C, and others. You can configure it once and apply custom security rules across your entire multi-language codebase, then tune false positives and enforce consistent policy across all projects.

SAST tools generate false positives through overly broad rules. Tune detection by adjusting rule sensitivity, creating exceptions for specific patterns, building baseline scans to ignore existing issues, and developing custom rules tailored to your codebase's architecture and security requirements.

All three detect vulnerabilities but differ in approach: Semgrep uses pattern matching for fast feedback, SonarQube provides comprehensive code quality and security analysis, CodeQL enables custom query-based detection. Choose based on your language support needs, pipeline speed requirements, and rule customization depth.

Yes. SAST tools allow custom rule development to enforce organization-specific security policies. Define rules for proprietary frameworks, dangerous API usage, or compliance requirements, then integrate them into automated scans across your CI/CD pipelines for consistent policy enforcement.
