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

Radboudumc is a leading academic medical center in the Netherlands focused on innovative, sustainable, and affordable healthcare. The website targets patients, healthcare professionals, researchers, and students, offering comprehensive information on patient care, research, and education. The institution maintains a strong market position as a reputable healthcare provider and research institute. The site features professional design, clear navigation, and multilingual support, reflecting a mature digital presence. Technically, the website employs modern analytics tools such as Matomo and Microsoft Application Insights for performance and error monitoring, alongside accessibility tools like ReadSpeaker. The infrastructure appears robust with HTTPS enforced and a moderate performance profile. The site is mobile-optimized and SEO-friendly, though no explicit CMS or framework is identified. From a security perspective, the site demonstrates good practices including encrypted connections, privacy-compliant cookie consent, and no visible sensitive data exposure. However, it lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms, which are recommended for enhanced trust and compliance. Overall, the website is professional, trustworthy, and compliant with GDPR, supporting Radboudumc's reputation as a credible healthcare institution. Strategic improvements in security transparency and header configurations could further strengthen its posture.

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

3 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Radboudumc operates as an essential healthcare entity providing patient care, research, and education. Its business model integrates clinical services with academic research and training, targeting a broad audience including patients and professionals. The institution benefits from strong brand recognition and partnerships such as with Radboud Fonds. Revenue streams likely include healthcare services, research grants, and educational programs. The website reflects a mature digital ecosystem with comprehensive content and active social media engagement, supporting growth and stakeholder communication. The partnership ecosystem includes charitable foundations and academic collaborators, enhancing its market reach and funding opportunities. The institution's strategic focus on innovation and sustainability positions it competitively within the healthcare sector.

Security posture

The website exhibits a good security maturity level with enforced HTTPS, use of advanced monitoring tools, and privacy-conscious cookie management. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure pages indicates room for improvement in transparency and preparedness. The use of third-party scripts is extensive but appears managed with privacy considerations. Compliance with GDPR is evident through detailed privacy and cookie policies with consent mechanisms. The security culture could be enhanced by publishing clear security governance documents and implementing security headers to mitigate common web threats.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Add security headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  5. Regularly review and audit third-party scripts and dependencies for vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack including Matomo for analytics, Microsoft Application Insights for telemetry, and ReadSpeaker for accessibility. The site is modular with ES6 JavaScript modules and CSS custom properties, indicating up-to-date front-end practices. Hosting appears to leverage cloud services for analytics and monitoring, while the main site hosting is not explicitly identified but likely stable and performant. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The absence of a known CMS suggests a custom or proprietary platform, which may require dedicated maintenance resources. Technical risks include reliance on multiple third-party scripts which should be monitored for security and performance impacts.
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.
