Datadog Runtime Code Analysis (IAST) is a commercial interactive application security testing tool by Datadog. 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, company size fit, deployment model, here is our conclusion:
Development teams already running Datadog APM will see immediate payoff from Datadog Runtime Code Analysis (IAST) because vulnerability findings flow directly into the observability context you're already using, cutting investigation time versus bolted-on IAST tools. The integration eliminates the context-switching that kills adoption of security findings in dev workflows. Skip this if your organization uses a different APM vendor or runs applications Datadog doesn't instrument well; you'll be retrofitting data flow analysis onto a platform that wasn't designed around your stack.
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.
