Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Contrast Application Security Testing (AST)
Development teams shipping code faster than they can manually review it should use Contrast Application Security Testing to catch real vulnerabilities before production without slowing the build pipeline. Its runtime instrumentation monitors actual code execution across Java, .NET, and Python, eliminating the false positives that plague static scanners, and integrates directly into Jenkins and GitHub workflows so findings surface where developers already work. Skip this if you need pre-deployment scanning as your primary defense; Contrast is strongest when your applications are already running and you can instrument them end-to-end.
Development teams shipping microservices and APIs into CI/CD pipelines need active verification that catches real vulnerabilities before production, and Black Duck Seeker IAST does this by instrumenting running applications to validate findings rather than relying on static analysis guesses. Its API discovery across REST, SOAP, and GraphQL plus gRPC support for microservices means you're actually testing what you built, not what a scanner thinks exists. Skip this if your stack is predominantly monolithic Java or .NET with slow release cycles; the tool's value compounds in high-velocity, containerized deployments where false positives crater developer trust.
