Security Posture Analysis
Comprehensive Security Assessment
The website enforces HTTPS and uses a cookie consent mechanism, indicating awareness of privacy and security requirements. However, DNSSEC is not enabled, and several important security headers such as Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy are missing, which could expose the site to certain web-based attacks. There is no visible security policy or incident response contact information, and no vulnerability disclosure or security.txt file is present. These gaps suggest room for improvement in transparency and proactive security management. No critical vulnerabilities or exposed sensitive data were detected in the analysis.
