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

The University of Luxembourg is an international research university characterized by its multilingual and interdisciplinary approach. The website serves as the official portal for academic programs, research activities, and university information targeting students, researchers, and the academic community. It positions itself as a medium-sized educational institution with a strong international presence and a focus on quality education and research. Technically, the website is built on WordPress with a modern tech stack including Yoast SEO for optimization, Matomo for analytics, and Cookiebot for consent management. The site demonstrates good mobile optimization, accessibility, and SEO practices, reflecting a mature digital infrastructure. Performance is moderate, with room for improvement in hosting and speed. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, but lacks explicit security headers and published security policies. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The absence of WHOIS data limits domain trust assessment, but the website's branding and content strongly support its legitimacy. Overall, the University of Luxembourg's website is professional, secure, and compliant with privacy regulations, though improvements in transparency around security policies and domain registration information are recommended to enhance trust and compliance.

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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

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 providing higher education and research services. Its market positioning is that of an international university with multilingual and interdisciplinary strengths, targeting students and researchers globally. The business model is focused on academic excellence and research output rather than commercial revenue streams. The website reflects a well-established institution with a consistent brand and a comprehensive digital presence including social media channels. Partnerships and collaborations are implied through social media and external links but no explicit partner domains were identified in the content. The university's growth indicators include active content updates and engagement with prospective students via digital platforms.

Security posture

The website exhibits a good security posture with mandatory HTTPS and cookie consent management in place. Use of Matomo analytics respects user privacy with consent requirements. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security or incident response policies indicate areas for improvement. No security.txt or vulnerability disclosure mechanisms were found, which could enhance transparency and incident handling readiness. The missing WHOIS data reduces confidence in domain registration legitimacy but does not directly impact website security. Overall, the security maturity is moderate to good, with recommendations to formalize policies and improve header configurations.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  4. Improve transparency by providing clear contact information including security and data protection officer contacts.
  5. Investigate and resolve WHOIS data availability issues to improve domain registration trustworthiness.

Technical notes

Notes

The website is built on a WordPress CMS platform enhanced with Yoast SEO Premium for search optimization and Cookiebot for GDPR-compliant cookie consent management. Analytics are handled via Matomo, a privacy-focused analytics tool. The site uses jQuery and integrates third-party video players from YouTube and Vimeo. The technical implementation shows good adherence to modern web standards with responsive design and accessibility features. Performance is moderate, likely influenced by external scripts and analytics. There is no explicit hosting provider identified from the content. The site could benefit from additional security headers and performance optimizations to reduce load times and improve security posture.
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.
