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 doing bulk URL reconnaissance or rapid XSS triage will appreciate extended-xss-search because it tests multiple XSS payloads per URL instead of stopping at the first match, catching bypasses that simpler finders miss. It's free and sits on 187 GitHub stars, meaning you can deploy it in a scanning pipeline without vendor lock-in or licensing overhead. Skip this if you need interactive exploitation or DAST integration with your WAF; extended-xss-search is a scanner for finding the vulnerability, not managing remediation workflows.
