CST VerdictShort answer
SMBs and mid-market teams without dedicated vulnerability management staff should pick AppCheck Infrastructure Scanner for its unlimited scanning and users, removing seat-based licensing friction that kills adoption. The proprietary VulnFeed database detects over 20,000 products and tens of thousands of CVEs with authenticated scanning that catches what surface-level tools miss, and RBAC plus role-based reporting let security generalists delegate tasks without handing out admin access. Skip this if your primary need is web application scanning; the infrastructure focus is strong, but the web scanning is secondary to the core network and data center mission. 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.
