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.
Privacy and compliance teams auditing third-party script exposure on public websites should start with Website Privacy Test; it maps cookie dependencies and identifies unauthorized trackers faster than manual inventory work, which matters when you're under pressure to document what's actually running. The tool ships free with no seat limits, so there's zero friction to run it across your entire web property before deciding on deeper GDPR or CCPA remediation tools. Skip this if your priority is blocking or rewriting scripts in real time; Website Privacy Test finds the problem, it doesn't fix it.
