Black Duck Seeker IAST is a commercial interactive application security testing tool by Black Duck Software, Inc.. Contrast One is a commercial interactive application security testing tool by Contrast Security. Compare features, ratings, integrations, and community reviews side by side to find the best interactive application security testing fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, 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.
Mid-market and enterprise security teams handling complex API estates will get the most from Contrast One, where runtime vulnerability detection actually prioritizes what matters by correlating observed attack routes with exploitability rather than flooding you with CVE noise. The platform scores strongly on NIST Continuous Monitoring and Risk Assessment, reflecting its strength in reducing triage overhead through guided remediation workflows. Skip this if your org runs mostly monolithic applications on-premises; Contrast One is built for distributed, cloud-native architectures where traditional static scanning leaves blind spots.
