Arachni is a free dynamic application security testing tool. 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:
Security teams evaluating open-source DAST tools for regression testing in CI/CD pipelines will find Arachni's low operational overhead and zero licensing friction valuable, especially when scanning your own applications repeatedly. The framework's modular architecture and scripting capabilities let you customize checks for legacy systems that commercial scanners often ignore. Skip this if you need managed scanning, compliance reporting templates, or a vendor to call when false positives spike; Arachni requires in-house expertise to tune effectively and produces raw vulnerability data you'll need to contextualize yourself.
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.
