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

7 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

      • 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 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

      GDPR requires clear information about cookie usage

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

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

MCH Group holds a leading market position in the media and event management industry, leveraging over a century of experience. Their business model focuses on high-profile art fairs, live marketing, and event infrastructure management, targeting galleries, artists, businesses, investors, and event attendees. The company benefits from a diversified portfolio including subsidiaries like MC² and Expomobilia. Their digital ecosystem integrates advanced marketing and analytics tools, supporting data-driven decision-making and customer engagement. The company maintains a strong brand presence and investor relations, indicating financial stability and growth potential. However, the lack of transparent domain registration data suggests a need for improved digital trust measures.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms in place. Use of reputable third-party analytics and marketing services is evident, with no exposed sensitive data or obvious vulnerabilities detected. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts indicate areas for enhancement. No vulnerability disclosure or security.txt files were found, which could improve transparency and incident handling readiness. Overall, the security posture is solid but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Verify and update WHOIS domain registration information to enhance domain legitimacy and trust.
  5. Continue monitoring and optimizing privacy compliance, especially regarding data retention and user consent.

Technical notes

Notes

The website uses a modern technology stack including JavaScript frameworks, Google Tag Manager, and analytics tools like Hotjar and Google Analytics. It is hosted likely behind Cloudflare, providing performance and security benefits. The site is mobile-optimized with responsive design and good accessibility features. SEO is supported by proper meta tags, Open Graph, and structured data using JSON-LD. Performance appears fast with preloading of CSS and scripts. No CMS was explicitly detected, suggesting a custom or proprietary solution. Technical risks are minimal, but improvements in security header implementation and domain registration transparency are recommended.
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.
