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

MERKUR CASINO a.s. is a well-established gambling operator in the Czech Republic, operating since 1992 and part of the global Gauselmann Group. The company offers physical casinos, an online casino platform (MerkurXtip), and customer loyalty programs. The website reflects a professional and consistent brand image targeting adult users interested in gambling services. Technically, the site uses modern web technologies including Google reCAPTCHA and Google Analytics, with a cookie consent mechanism aligned with GDPR requirements. Security posture is generally strong with HTTPS enforced and bot protection, though some security headers are missing and no explicit incident response or vulnerability disclosure policies are found. The absence of WHOIS data limits domain trust analysis but the overall business credibility remains high based on content and affiliations.

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

  2. Security headers

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

The company holds a leading market position in the Czech gambling sector, leveraging both physical and online platforms. Its business model focuses on casino gaming, betting, and customer engagement through loyalty programs. The parent company Gauselmann Group provides strong backing. The website's marketing tools and analytics indicate a mature digital presence. Partnerships with related domains like MerkurXtip and Gauselmann.de reinforce its ecosystem. Growth indicators include active promotions and a clear focus on GDPR compliance. The company targets adult customers with a focus on responsible gambling.

Security posture

The website demonstrates a good security maturity level with HTTPS, reCAPTCHA integration, and cookie consent mechanisms. However, the lack of security headers and absence of published security policies or incident response contacts represent gaps. No vulnerabilities or exposed sensitive data were detected in the content. GDPR compliance is evident but could be enhanced with more transparent security disclosures. Incident response readiness and vulnerability disclosure mechanisms are not visible, which could impact trust in security incident handling.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and user trust.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website uses a modern technology stack including Google reCAPTCHA for bot mitigation, Google Tag Manager and Analytics for tracking, and Owl Carousel for UI elements. The site is mobile optimized with responsive design and uses Google Fonts for typography. Performance is moderate with asynchronous loading of scripts. No CMS or hosting provider is explicitly identified. SEO is supported by proper meta tags and Open Graph images. Accessibility is basic but could be improved. The absence of security headers is a technical risk. Overall, the infrastructure supports a professional online presence but could benefit from enhanced security and accessibility modernization.
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.
