CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Startups and mid-market teams that can't afford false positives drowning their backlogs should run AppCheck DAST Tool; its browser-based crawling handles modern SPAs and APIs without the noise that drives developers to ignore scan results. Automated authentication with MFA and TOTP support means you actually test authenticated flows instead of settling for unauthenticated scans, and the out-of-band detection catches timing-based vulnerabilities most tools miss. Skip this if you need deep API fuzzing or heavy CSPM coverage; AppCheck is built for application-layer velocity, not infrastructure risk orchestration.
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.
