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.
DevOps and platform teams deploying CloudFormation at scale need CFRipper because it catches misconfigurations in templates before they reach AWS, eliminating the costly fix-forward cycle most teams accept. The tool is free and sits in your CI/CD pipeline, meaning zero friction to adoption and immediate shift-left on infrastructure security. Skip this if your organization uses Terraform or CDK as the primary IaC framework; CFRipper is CloudFormation-only and won't extend to other template languages.
