CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
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.
