CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startup development teams shipping fast need Perisai Web Scanner because it catches vulnerable dependencies and misconfigured headers in minutes without requiring infrastructure changes. The free tier covers automated scanning across JavaScript libraries and HTTP security posture, removing the cost barrier that usually delays security scanning adoption. Skip this if you're managing legacy monoliths with hundreds of interconnected services or need continuous runtime monitoring post-deployment; Perisai maps application risk at scan time, not in production.
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.
