How do I verify Claude code is secure?

Verifying Claude-generated code security requires a multi-layer approach. First, review the generated code against the OWASP Top 10 checklist, paying special attention to authentication, access control, and data validation logic. Second, cross-reference any libraries or APIs Claude suggests with their official documentation to confirm they exist and are used correctly. Third, deploy to a staging environment and run both automated security scans and manual penetration testing against the live application. Finally, verify that security headers, SSL configuration, and DNS security are properly configured at the infrastructure level. UNPWNED automates the external scanning layer, running 700+ security checks across 40 scanners against your deployed application.
