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.
Startup and SMB security teams with limited scanning budgets should start with Astra Website Scanner; the free tier covers malware and SEO spam detection while the paid plans unlock authenticated scanning and API testing without enterprise pricing. The 9,300+ vulnerability test cases and CI/CD integrations mean you can catch real issues before deployment, and continuous automated rescans verify that fixes actually stick. Skip this if you need SAST or infrastructure scanning; Astra is application-surface focused and won't tell you what's wrong with your cloud configuration.
