cmzs.cz received a security score of 51 out of 100 in Guard's comprehensive security analysis, classified as "Elevated Risk". This report covers Cech mechanických zámkových systémů ČR's website security posture. Cech mechanických zámkových systémů ČR operates in the Other industry in Czech Republic.

The website cmzs.cz represents the Cech mechanických zámkových systémů ČR (CMZS), a Czech organization uniting professionals in the field of mechanical lock systems, key manufacturing, and lock installations. The site serves both industry experts and the general public, offering services such as a product catalog, security projects, and a member search feature. The business is positioned as a trusted entity within the Czech Republic's security and locksmith sector, founded in 2007, with a small organizational size and a clear focus on mechanical lock systems. Technically, the website employs modern web technologies including JavaScript, SVG graphics, and Google Tag Manager for analytics. It is hosted under the registrar REG-GRANSY, with a domain age consistent with the organization's history. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. However, it lacks some advanced security headers and explicit privacy and cookie policies, which are important for compliance and user trust. From a security perspective, the site uses HTTPS and asynchronous script loading, which are positive indicators. No visible vulnerabilities or exposed sensitive data were detected. The absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms represents an area for improvement. Analytics usage is moderate, primarily via Google Tag Manager, but privacy compliance is weak due to missing policies. Overall, the website is safe, professional, and trustworthy, with a solid business foundation. Strategic recommendations include implementing comprehensive privacy and cookie policies, enhancing security headers, and providing clear incident response and vulnerability disclosure information to improve compliance and security posture.

Security Posture Analysis

Comprehensive Security Assessment

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. Use of Google Tag Manager indicates tracking but no malicious scripts were found. The lack of security headers such as Content-Security-Policy and X-Frame-Options is a gap. No published incident response or vulnerability disclosure policies reduce transparency and readiness. Compliance with GDPR is uncertain due to missing privacy and cookie policies. The site uses secure forms but does not provide explicit security assurances. Overall, the security culture appears basic but functional, with room for improvement in policy publication and header implementation.

Strategic Recommendations

Priority Actions for Security Improvement

1

Publish comprehensive privacy and cookie policies to ensure GDPR compliance and user trust.
