Security Posture Analysis
Comprehensive Security Assessment
The website enforces HTTPS and uses secure forms with validation and GDPR-compliant consent checkboxes. Cookie consent is managed via CCM19, ensuring user privacy choices are respected. However, no explicit security policy or incident response contact is published, which could be improved. Security headers are partially implied but not explicitly confirmed in the HTML. No vulnerabilities or exposed sensitive data were detected. The integration of third-party scripts like Google Tag Manager and Ads is handled with consent, reducing privacy risks. Overall, the security maturity is good but could benefit from formalized policies and vulnerability disclosure mechanisms.
Strategic Recommendations
Priority Actions for Security Improvement
Publish a clear security policy and incident response contact information on the website.
