Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a good security baseline with HTTPS enabled and no exposed sensitive data. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is published, which could hinder rapid response to security issues. Privacy compliance is minimal, lacking clear privacy and cookie policies or consent mechanisms. The security culture appears professional but could benefit from enhanced transparency and formalized policies. Overall, the security posture is solid but not comprehensive.
Strategic Recommendations
Priority Actions for Security Improvement
Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
