CST VerdictShort answer
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. Development teams protecting Java and PHP applications from injection attacks and data exfiltration will get the most from OpenRASP because it instruments application code directly rather than relying on network signatures that miss context-aware exploits. The 2,956 GitHub stars and active community reflect real adoption in production environments where developers can see exactly which requests trigger blocking rules. Skip this if you need mobile app protection on iOS or Android; OpenRASP focuses on server-side application security and won't help you secure client-side code.
