Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Datadog Runtime Code Analysis (IAST)
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.
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.
