Static Application Security Testing vs Interactive Application Security Testing

Developers should use SAST to proactively identify and fix security vulnerabilities during the development phase, reducing the cost and risk of late-stage remediation meets developers should use iast during the development and testing phases of the software development lifecycle, particularly in ci/cd pipelines, to identify and remediate security vulnerabilities early. Here's our take.

Static Application Security Testing

Nice Pick

Developers should use SAST to proactively identify and fix security vulnerabilities during the development phase, reducing the cost and risk of late-stage remediation

Pros

• It is essential for compliance with security standards (e
• Related to: dynamic-application-security-testing, software-security

Cons

• Specific tradeoffs depend on your use case

Interactive Application Security Testing

Developers should use IAST during the development and testing phases of the software development lifecycle, particularly in CI/CD pipelines, to identify and remediate security vulnerabilities early

Pros

• It is especially valuable for web applications, APIs, and microservices where real-time analysis can catch issues that static tools might miss, such as runtime configuration problems or business logic flaws
• Related to: static-application-security-testing, dynamic-application-security-testing

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Static Application Security Testing if: You want it is essential for compliance with security standards (e and can live with specific tradeoffs depend on your use case.

Use Interactive Application Security Testing if: You prioritize it is especially valuable for web applications, apis, and microservices where real-time analysis can catch issues that static tools might miss, such as runtime configuration problems or business logic flaws over what Static Application Security Testing offers.

The Bottom Line

Static Application Security Testing wins

Developers should use SAST to proactively identify and fix security vulnerabilities during the development phase, reducing the cost and risk of late-stage remediation
