Security Posture Analysis
Comprehensive Security Assessment
The website employs HTTPS with good SSL configuration and includes privacy and security policy pages aligned with GDPR. While no critical vulnerabilities or exposed sensitive data were found, the absence of explicit security headers like CSP or HSTS is noted. There is no visible incident response or vulnerability disclosure page, which could improve security transparency. The use of third-party scripts is standard but should be regularly audited. Overall, the security posture is good but can be enhanced with additional headers and formal incident response documentation.
Strategic Recommendations
Priority Actions for Security Improvement
Implement security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to strengthen protection against common web attacks.
