Security Posture Analysis

Comprehensive Security Assessment

The website enforces HTTPS with excellent SSL configuration and employs multiple security headers such as Content Security Policy and Strict-Transport-Security. Scripts and stylesheets include integrity attributes, reducing the risk of tampering. No sensitive data or vulnerable libraries are exposed in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms limits transparency and readiness for security incidents. Privacy compliance is good but could be enhanced with explicit cookie consent and clearer data protection officer contact information. Overall, the security posture is solid but could benefit from improved policy disclosures and user-facing security communications.

Strategic Recommendations

Priority Actions for Security Improvement

1

Implement a visible cookie consent banner to comply fully with GDPR and enhance user trust.
