Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data leaks. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents a gap in best practices. No vulnerability disclosures or incident response contacts are published, limiting transparency. GDPR compliance is partial, with cookie consent but no explicit privacy policy. The security culture could be enhanced by formalizing policies and improving technical defenses. No critical vulnerabilities were detected, but improvements are recommended to mitigate potential risks.
