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.
Teams scanning Infrastructure as Code across multiple cloud platforms need Terrascan because it catches misconfigurations before deployment at zero cost, eliminating the vendor lock-in that makes other IaC scanners risky for multi-cloud shops. With 5,144 GitHub stars and active community maintenance, it's proven in production environments where Terraform, CloudFormation, and Kubernetes manifests live side-by-side. Skip this if your organization needs deep policy customization or native IDE integration; Terrascan's strength is breadth of platform coverage, not depth of controls within a single cloud ecosystem.
