Risk levelMedium

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

Universitätsklinikum Düsseldorf is a major university hospital in Germany providing healthcare, medical research, and education services. The website is professionally designed using TYPO3 CMS and includes modern features such as cookie consent management via Cookiebot and analytics tracking with Matomo. The site targets patients, medical professionals, researchers, and students, reflecting its academic and healthcare mission. Technical infrastructure is solid with moderate performance and good mobile optimization. Security posture is adequate with HTTPS usage and cookie consent, but lacks visible security headers and published security policies. Privacy compliance is partially met with cookie consent but no explicit privacy policy found in the provided content. Overall, the website is trustworthy and professional, though improvements in security transparency and contact information visibility are recommended.

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 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 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';…

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 website represents a large healthcare institution with a focus on patient care, research, and education. It holds a strong market position as a university hospital in Düsseldorf, Germany. The business model centers on healthcare services and academic activities. The site does not reveal detailed revenue streams or partnerships but uses standard web technologies and analytics tools. The absence of visible contact details and legal policies in the provided content suggests areas for enhancement in transparency and user engagement. The institution likely benefits from established reputation and trust in the healthcare sector.

Security posture

The current security maturity level is moderate. HTTPS is enforced, and cookie consent mechanisms are implemented, indicating awareness of privacy regulations. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No vulnerability disclosure or incident response information is published, which limits transparency and readiness perception. No exposed sensitive data or vulnerable libraries were detected. The site would benefit from publishing security policies, implementing additional HTTP security headers, and providing clear incident response contacts to improve security culture and compliance.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  3. Add a security.txt file or vulnerability disclosure page to facilitate responsible reporting.
  4. Make contact information including security and incident response contacts clearly visible.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system. It uses jQuery 2.2.0 and integrates Matomo for analytics and Cookiebot for consent management. The site shows good mobile optimization and SEO practices with proper meta tags and canonical URLs. Performance is moderate, likely due to compressed CSS and JS assets. No hosting provider details were found. The technical stack is modern but could be improved by updating jQuery to a more recent version and enhancing accessibility compliance. No critical technical debt or risks were identified in the provided content.
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.
