Security Posture Analysis

Comprehensive Security Assessment

The website demonstrates a high security maturity level with HTTPS enforced, comprehensive security headers, and use of reCAPTCHA to protect forms. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Compliance with GDPR is indicated through privacy and cookie policies with consent mechanisms. The security score is strong but could be enhanced by publishing explicit security governance documents and providing direct security contact channels.
