Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a basic security posture with HTTPS enabled and no visible vulnerabilities or exposed sensitive data. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. Lack of privacy and cookie policies indicates compliance gaps with GDPR and other regulations. No incident response or vulnerability disclosure information is provided, limiting transparency. The use of Google Tag Manager introduces moderate tracking but without clear privacy disclosures. Overall, security maturity is moderate but can be significantly improved by adding security headers, formal policies, and contact information for security incidents.
