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

5 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 MERKUR GROUP operates in the gaming and hospitality industry, offering a broad portfolio including slot machines, casinos, online gaming, and financial services. Their business model focuses on product development, operation, and service provision within regulated markets. The company has a strong market position supported by a large employee base and a history dating back to 1957. Their digital presence supports recruitment and corporate communication, with active social media engagement. Partnerships and acquisitions, such as the takeover of Oasis Retail Services in the UK, indicate growth and market expansion. The company emphasizes responsible gaming and sustainability, which are key differentiators in the industry.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement and integration of a consent management platform (Usercentrics) for GDPR compliance. Tracking and analytics are managed responsibly with Matomo and Google Tag Manager. However, the absence of explicit security policies, incident response information, and a security.txt file suggests room for improvement in transparency and readiness. Security headers are partially present but could be enhanced to mitigate common web threats. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could benefit from formalized policies and disclosures.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  3. Enhance HTTP security headers such as HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information for security incidents, including abuse and security email addresses.
  5. Improve accessibility features to meet higher compliance standards and broaden user inclusivity.

Technical notes

Notes

The website is built using modern web technologies including Bootstrap for responsive design, Swiper.js for interactive sliders, and integrates analytics tools like Matomo and Google Tag Manager. It employs a consent management platform (Usercentrics) to comply with privacy regulations. The site is mobile-optimized with good navigation clarity and consistent branding. Performance is moderate, with video content and multiple scripts that may impact load times. No CMS was explicitly detected, suggesting a custom or proprietary solution. The technical infrastructure supports a professional corporate presence but could be optimized further for speed and accessibility.
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.
