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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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';…

  3. GDPR outside view

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

    • 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

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

Messe Düsseldorf GmbH operates this platform as part of its extensive portfolio of trade fairs and events. The website supports multiple languages through related domains, indicating a global outreach strategy. The business benefits from strong partnerships within the event and exhibition industry, leveraging digital tools to enhance exhibitor and visitor engagement. The presence of specialized portals like the stand builder and online order system reflects a mature ecosystem supporting exhibitors. The site’s content and navigation are structured to facilitate user journeys for different stakeholder groups, enhancing the overall business value proposition.

Security posture

The website employs HTTPS with a good SSL configuration, ensuring secure data transmission. It integrates a cookie consent mechanism via Usercentrics CMP, demonstrating compliance efforts with privacy regulations. Multiple third-party scripts for analytics and advertising are used, which require ongoing monitoring for vulnerabilities. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms were found, indicating areas for improvement. Security headers and advanced protections are not explicitly detected in the provided data. Overall, the security posture is solid but could be enhanced by publishing formal security and privacy documentation and implementing additional HTTP security headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Add explicit contact information including emails and phone numbers for general and security-related inquiries.
  3. Implement and document a security policy and incident response procedures accessible to users.
  4. Enhance HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  5. Regularly audit and update third-party scripts to mitigate risks from external dependencies.

Technical notes

Notes

The website uses a mix of modern and legacy technologies including jQuery, Usercentrics CMP for cookie management, Matomo for analytics, and various advertising and tracking scripts. The site is mobile-optimized with responsive design elements and good SEO metadata including Open Graph and JSON-LD structured data for event information. Hosting details are not explicit but likely managed by Messe Düsseldorf or a trusted provider. Performance is moderate with room for optimization. Accessibility features are basic but present. The CMS is not explicitly identified, suggesting a custom or proprietary solution. Overall, the technical infrastructure supports the business needs effectively but could benefit from modernization and enhanced security controls.
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.
