Security Posture Analysis

Comprehensive Security Assessment

The security maturity level of G&L is solid, evidenced by ISO 27001 certification and enforced HTTPS. The website employs cookie consent management compliant with GDPR, indicating good data protection practices. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security headers like Content Security Policy (CSP), HSTS, and X-Frame-Options suggests room for improvement. There is no public incident response or abuse contact information, which could hinder timely handling of security incidents. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. Overall, the security culture appears professional but could benefit from enhanced transparency and technical hardening.
