Rapid7 InsightAppSec is a commercial dynamic application security testing tool by Rapid7. Checkmarx One DAST is a commercial dynamic application security testing tool by Checkmarx. Compare features, ratings, integrations, and community reviews side by side to find the best dynamic 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 and mid-market security ops will get the most from Rapid7 InsightAppSec because it handles API scanning alongside traditional web app testing without requiring separate tools or workflow context-switching. The tool covers 95+ attack types and integrates directly into Jira, meaning vulnerability triage happens where developers already live instead of in a standalone portal. Skip this if your organization needs SAST or supply-chain scanning; InsightAppSec is DAST-only and won't catch code-level risks before deployment.
Mid-market and enterprise security teams already running Checkmarx SAST will find Checkmarx One DAST indispensable for closing the runtime visibility gap; the centralized API inventory that correlates SAST and DAST findings eliminates the manual work of hunting down which backend endpoints actually matter. Browser-based authentication recording and multi-step login handling mean you'll actually test real user flows instead of abandoning DAST when login gets complicated. Skip this if your organization needs runtime protection that includes API threat prevention and response; Checkmarx One DAST finds vulnerabilities but doesn't block them in production.
