CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

Katana

Security teams running reconnaissance workflows or building custom crawling pipelines will get the most from Katana; the 14K GitHub stars reflect genuine adoption by practitioners who need fine-grained control over spidering logic rather than point-and-click scanners. The framework approach means you're writing code to extract what matters to your target scope, which beats generic crawlers for complex authentication flows or JavaScript-heavy applications. Skip this if your team lacks engineering resources or needs a managed SaaS interface; Katana requires Python knowledge and infrastructure to operationalize.
