0–100, higher is better. How it is calculated

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.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CMZS operates as an important organizational entity within the mechanical lock and security systems sector in the Czech Republic. Its business model revolves around uniting professionals, providing a trusted product catalog, and running security-related projects. The target customers include locksmiths, security system installers, and citizens seeking security solutions. The organization benefits from a long-established domain and consistent branding. Partnerships with official entities such as the Czech police enhance its credibility. Revenue streams likely include membership fees, product recommendations, and project collaborations. Growth indicators include active project pages and a member search feature. The partnership ecosystem includes police prevention websites and technology providers. The organization's operations are focused and specialized, with a clear market niche.

Security posture

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.

Recommendations

  1. Publish comprehensive privacy and cookie policies to ensure GDPR compliance and user trust.
  2. Implement security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear incident response and vulnerability disclosure contact information on the website.
  4. Enhance accessibility features to improve usability for all users.
  5. Develop a long-term security strategy including regular audits and user data protection measures.

Technical notes

Notes

The website uses a modern tech stack with JavaScript components, SVG graphics, and asynchronous script loading for performance. Google Tag Manager is integrated for analytics and marketing. The site is mobile-optimized with responsive CSS stylesheets. Hosting and DNS are managed by REG-GRANSY, consistent with the domain registrar. Performance is moderate with no major issues detected. Technical debt is low, but the absence of some security headers and privacy compliance features indicates areas for modernization. The site could benefit from enhanced SEO metadata and structured data for improved search visibility.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
