Introduction
Static Application Security Testing (SAST) tools analyze source code to identify security vulnerabilities before deployment, catching issues like SQL injection, XSS, and hardcoded credentials during development.
Effective SAST implementation requires three capabilities: broad language support matching your tech stack, IDE integration for real-time feedback as developers code, and CI/CD pipeline integration to fail builds with critical findings.
This comparison examines 5 SAST platforms ranging from open-source SonarQube to enterprise solutions with AI-powered remediation.
Each tool approaches code analysis differently - SonarQube emphasizes code quality metrics alongside security, Snyk Code focuses on speed and developer experience, Checkmarx One provides unified AppSec with ASPM correlation, Veracode offers managed scanning with expert support, and Qwiet specializes in dataflow analysis.
Selection depends on your organization size, supported languages, existing toolchain, and whether you need self-hosted or SaaS deployment.
