Security Posture Analysis

Comprehensive Security Assessment

The security maturity of Common.fi is high, evidenced by HTTPS enforcement, DNSSEC, and multiple third-party security audits. The platform avoids exposing sensitive data in its web content and uses modern security best practices. However, the absence of a published security policy, incident response plan, or security.txt file limits transparency for vulnerability reporting. GDPR compliance is indicated by a comprehensive privacy policy and cookie consent mechanism. No critical vulnerabilities or exposed credentials were detected. The platform would benefit from publishing explicit security and incident response documentation to enhance trust and readiness.
