Application Security Tools FAQ
Common questions about Application Security tools, selection guides, pricing, and comparisons.
SAST (Static Application Security Testing) analyzes source code without running the application, catching vulnerabilities early in development. DAST (Dynamic Application Security Testing) tests running applications by sending requests and analyzing responses, finding runtime vulnerabilities. IAST (Interactive Application Security Testing) combines both by instrumenting the application during testing, providing real-time analysis with lower false positive rates than SAST or DAST alone.
A mature AppSec program typically includes: SAST for code-level vulnerability detection, SCA for open-source dependency risks, DAST for runtime testing, API security for protecting endpoints, secure code training for developers, and ASPM to unify visibility across all these tools. Start with SCA and SAST as they catch the most common vulnerabilities earliest in the development lifecycle.
Shift-left security means integrating security testing earlier in the software development lifecycle, ideally at the coding and CI/CD stages rather than waiting for production deployment. This approach uses tools like SAST, SCA, and IDE security plugins to catch vulnerabilities before they reach production, reducing remediation cost by up to 100x compared to finding issues in production.
SCA focuses specifically on identifying vulnerabilities in third-party libraries, open-source components, and software dependencies your application uses. SAST analyzes your own source code for security flaws. Since modern applications are 70-90% open-source code, SCA is essential for catching vulnerabilities in components you did not write but are responsible for securing.
