Security Posture Analysis

Comprehensive Security Assessment

Cube 5's website security posture is solid, with HTTPS enforced and no visible exposure of sensitive data or vulnerable libraries. The use of Matomo analytics suggests a privacy-conscious approach compared to mainstream trackers. However, the lack of explicit security headers like X-Frame-Options and X-Content-Type-Options, and the absence of a published security policy or incident response contact, represent gaps in transparency and readiness. GDPR compliance is supported by a comprehensive privacy policy, but the missing cookie consent mechanism could pose compliance risks. Incident response readiness and vulnerability disclosure practices are not publicly documented, which could impact trust from security-conscious stakeholders.

Strategic Recommendations

Priority Actions for Security Improvement

1

Implement a visible cookie consent banner to comply with GDPR and enhance user trust.
