84/100

Risk levelLow

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

Tilburg University is a reputable higher education institution based in the Netherlands, offering a wide range of bachelor's and master's programs, with a strong emphasis on research and international community engagement. The website reflects a professional and well-maintained digital presence, leveraging modern technologies such as Drupal 10 and integrating Google Analytics and Google Custom Search for enhanced user experience and data insights. Privacy and cookie compliance are well addressed with clear policies and user consent mechanisms. Security posture is generally strong with HTTPS enforced and no visible sensitive data exposure, though the absence of security headers suggests room for improvement. The WHOIS data for the www subdomain is missing, likely due to querying a subdomain rather than the main domain, but the website's branding and content strongly support its legitimacy. Overall, the site is trustworthy, user-friendly, and compliant with relevant privacy regulations.

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. 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"

      • ASVS V3.4.1

      Missing Content-Security-Policy header

  2. 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.

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 university holds a strong market position, ranked in the top 40 worldwide for Business & Economics and Law, targeting students, researchers, alumni, and corporate partners. Its business model centers on education and research services, supported by a robust online presence and active collaboration initiatives. The site demonstrates consistent branding and provides comprehensive contact and support information, enhancing credibility and user trust. The integration of social media channels and event calendars indicates active engagement with its community and stakeholders.

Security posture

The website employs HTTPS and cookie consent mechanisms, indicating a baseline security awareness. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options may expose the site to certain risks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published incident response or vulnerability disclosure page suggests an opportunity to enhance transparency and readiness. Overall, the security posture is solid but could benefit from implementing additional HTTP security headers and formalizing incident response communications.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to strengthen defense against common web attacks.
  2. Publish an incident response and vulnerability disclosure page or security.txt file to improve transparency and facilitate responsible reporting.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance monitoring and validation of form inputs to prevent injection attacks and data leaks.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, ensuring a solid foundation for content management and security. It uses Google Analytics and Google Custom Search Engine for analytics and search functionality, respectively. The site is mobile-optimized with responsive design and accessibility features, providing a good user experience across devices. Performance is moderate, with asynchronous loading of scripts and optimized images. The absence of certain security headers and incomplete WHOIS data for the www subdomain are notable technical gaps. Hosting provider details are not explicitly identified from the content. Overall, the technical infrastructure is robust but could be enhanced with additional security configurations and WHOIS clarity.
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.
