Data Theorem Web Secure is a commercial dynamic application security testing tool by Data Theorem. 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, company size fit, deployment model, here is our conclusion:
Development teams shipping web applications need Data Theorem Web Secure because it tests code, dependencies, and running applications in a single workflow, cutting the friction of bolting together separate SAST and DAST tools. The platform covers NIST ID.AM and ID.RA through automated asset discovery and embedded API testing that most AppSec scanners skip entirely. Skip this if your primary concern is infrastructure or cloud configuration; Data Theorem is application-focused, not a platform security scanner.
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.
