Risk levelLow

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

The University of Luxembourg is an international research university with a multilingual and interdisciplinary character, serving students and researchers primarily in Luxembourg. The website reflects a professional academic institution with a focus on education and research services. The digital infrastructure is built on WordPress with advanced SEO and privacy tools such as Yoast SEO Premium, Matomo analytics, and Cookiebot for cookie consent management. The site demonstrates good mobile optimization, accessibility, and user experience. Security posture is solid with HTTPS and privacy-aware analytics, though explicit security headers and incident response information are lacking. WHOIS data is unavailable, limiting domain trust assessment, but the website content and branding strongly support legitimacy. Overall, the site is well-maintained, privacy-conscious, and professionally presented.

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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

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

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. 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.

    • Medium

      DMARC not enforcing

      DMARC policy is set to "none"

      What to do: Gradually move to "quarantine" then "reject" policy

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  4. 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.

    • Medium

      SSL Certificate Expires Within 90 Days

      SSL certificate expires in 35 days

      What to do: Plan SSL certificate renewal

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 of Luxembourg operates as a public educational institution targeting students, academics, and researchers. Its market position is that of a reputable international research university. The business model centers on providing higher education and research programs. The website's content quality and SEO indicate a mature digital presence. Partnerships and social media presence are evident but no direct partner domains were identified. The absence of explicit contact details and WHOIS data suggests room for improvement in transparency. The university likely relies on public funding and academic collaborations as revenue streams. Growth indicators include active social media and multilingual content.

Security posture

The website employs HTTPS and integrates a cookie consent mechanism aligned with GDPR principles, using Cookiebot and Matomo analytics with consent enforcement. However, no explicit security headers (e.g., CSP, HSTS) were detected in the provided content. There is no visible security policy, incident response plan, or vulnerability disclosure mechanism published. No exposed sensitive data or vulnerable libraries were found. The security score is good but could be improved by adding formal security documentation and headers. Incident response readiness and security culture indicators are not evident from the content.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages with clear URLs.
  2. Add security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Include clear contact information such as official emails and phone numbers for user support and security concerns.

Technical notes

Notes

The website is built on WordPress CMS with advanced SEO via Yoast SEO Premium. It uses Matomo for privacy-focused analytics and Cookiebot for cookie consent management, indicating a modern and privacy-aware tech stack. External integrations include YouTube and Vimeo APIs for media content. The site is mobile optimized and accessible with good SEO metadata and structured data (JSON-LD). Performance is moderate, likely due to multiple external scripts. No major technical debt or deprecated libraries were detected. Hosting provider details are not explicit. The site could benefit from enhanced security headers and performance optimizations.
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.
