Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a mature security posture with mandatory HTTPS, domain transfer lock, and reputable registrar usage. However, the absence of DNSSEC and missing security headers such as Content-Security-Policy and X-Frame-Options represent areas for improvement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a public security policy or incident response contact limits transparency in security governance. No vulnerability disclosure or security.txt file is present, which could enhance trust and incident handling. Overall, the security maturity is good but could be elevated by adopting additional best practices and explicit security communications.
Strategic Recommendations
Priority Actions for Security Improvement
