Comprehensive Security Assessment

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and GDPR-compliant consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a publicly accessible security policy or incident response contact limits transparency. There is no evidence of vulnerability disclosure programs or security.txt files.
