FAQ

• How does Contrast Assess work, and what makes it different from traditional SAST or DAST?
  Contrast Assess uses an agent that instruments the running application with sensors. These sensors continuously monitor the application's code execution, data flow, and configuration in real time as it is executed. This Interactive Application Security Testing (IAST) approach, which combines static and dynamic analysis from within the application, pinpoints actual vulnerable, exploitable lines of code, drastically reducing false positives compared to standalone SAST or DAST.
• Can Contrast Assess be used by developers, or is it only for AppSec teams?
  Contrast Assess is designed for both developers and AppSec teams, streamlining the DevSecOps workflow. Developers receive immediate, actionable security feedback that pinpoints vulnerable lines of code and remediation guidance directly within their IDE, test or QA environments as they code, making security a continuous part of development. AppSec teams benefit from a centralized view of high-fidelity results, which eliminates the need to manually sift through false positives.
• What kind of vulnerabilities can Contrast Assess detect in my applications?
  Contrast Assess can identify a broad range of vulnerabilities in custom code, open-source libraries, frameworks and application configurations. This includes common risks like SQL injection, Cross-Site Scripting (XSS), insecure configurations and others detailed in the OWASP Top Ten list. It also pinpoints the vulnerable lines of code and the full data flow path, making remediation faster.
• How does Contrast Assess handle open-source and third-party libraries?
  Contrast Assess integrates with the platform's Software Composition Analysis (SCA) capability to identify third-party libraries and their known vulnerabilities. Crucially, it provides runtime context to determine if a vulnerable method in a library is actually being called and used by the running application, allowing teams to prioritize remediation efforts based on true, active risk.
