Data Theorem Web Secure is a commercial dynamic application security testing tool by Data Theorem. Qualys TotalAppSec is a commercial dynamic application security testing tool by Qualys. 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 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 with sprawling web applications and APIs across multiple clouds will get the most from Qualys TotalAppSec because its AI-assisted clustering actually reduces scan overhead on large attack surfaces instead of just generating more noise. The tool covers OWASP Top 10 and API Top 10 with continuous monitoring and integrates third-party pen test findings from Burp and BugCrowd, which means you're not rebuilding your threat picture across disconnected tools. Skip this if your priority is SAST or supply chain scanning; Qualys TotalAppSec does runtime application security well but doesn't shift left into code repositories.
