Compare features, ratings, integrations, and community reviews side by side to find the best dynamic application security testing fit for your security stack.
CST VerdictBased 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.
