Security Posture Analysis

Comprehensive Security Assessment

The website demonstrates a moderate security posture with HTTPS assumed but no explicit security headers detected in the HTML source. Forms collect user data but lack visible advanced protections such as CAPTCHA or CSRF tokens. No privacy or cookie policies are present, indicating compliance gaps with GDPR and related regulations. The absence of vulnerability disclosure or incident response information suggests limited formal security governance. No exposed sensitive data or vulnerable libraries were detected in the source. Overall, the security maturity is moderate but could be significantly improved by implementing security headers, privacy notices, and formal incident response channels.

Strategic Recommendations

Priority Actions for Security Improvement
