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

Fondation Restena is a Luxembourg-based non-profit foundation that manages telecommunication infrastructure and services for the research, education, culture, health, and administration sectors in Luxembourg. It operates the national research and education network, manages the .lu domain registry, and provides a range of services including email, hosting, network connectivity, and IT security. The foundation is well-established, with origins dating back to 1989 and formal foundation status since 2000. Their market position is strong as a key national infrastructure provider with a focus on public and academic institutions. Technically, the website is built on Drupal 8, featuring modern web technologies and good mobile optimization. The site is well-structured with clear navigation and professional design. Security posture is strong, supported by ISO 27001 certification and secure form handling, although some security headers are not visibly implemented. Privacy compliance is partial, with a privacy policy present but lacking a cookie consent mechanism. Overall, the security posture is robust with dedicated incident response services (CSIRT) and ongoing certification efforts. No major vulnerabilities or suspicious patterns were detected. The domain WHOIS data aligns well with the website content, confirming legitimacy and consistency. Strategic recommendations include enhancing privacy compliance with cookie consent, adding security headers, and publishing a vulnerability disclosure policy to further strengthen trust and security culture.

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.

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

Fondation Restena holds a critical position in Luxembourg's research and education ecosystem by providing essential network and domain registry services. Their non-profit model focuses on serving public institutions, which supports stable and trusted operations. The foundation's partnerships and projects, such as LU-CIX and cybersecurity initiatives, indicate active engagement in advancing national digital infrastructure. Their business model relies on service provision to a defined community rather than commercial revenue streams. Growth indicators include recent ISO recertification and new service offerings like DNS firewall. The foundation's ecosystem includes collaborations with national and international research networks, enhancing its competitive advantage and strategic relevance.

Security posture

The foundation demonstrates a mature security posture with ISO 27001 certification and a dedicated CSIRT team to handle cybersecurity incidents. The website and services show secure design practices such as HTTPS usage and secure AJAX forms. However, the absence of visible security headers and a vulnerability disclosure policy suggests room for improvement in transparency and defense-in-depth. GDPR compliance is mostly addressed through privacy policies, but cookie consent mechanisms are missing, which could be a compliance risk. Incident response readiness appears strong, supported by active projects focused on cybersecurity training and infrastructure. Overall, the security culture is proactive but could benefit from enhanced communication and technical controls.

Recommendations

  1. Implement a cookie consent banner to ensure GDPR compliance and user transparency.
  2. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to improve defense against common web attacks.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve trust.
  4. Regularly audit and update third-party libraries and CMS components to mitigate potential vulnerabilities.
  5. Enhance user awareness and trust by highlighting security certifications and incident response capabilities more prominently on the website.

Technical notes

Notes

The website uses Drupal 8 CMS with custom theming and JavaScript for interactive elements such as sliders and AJAX forms. The site is mobile-optimized and accessible, with proper meta tags and multilingual support (French and English). Performance is moderate, with no major blocking scripts detected. Hosting provider details are not explicitly found. The site lacks some modern security headers and cookie consent mechanisms, which are recommended for compliance and security. Overall, the technical infrastructure is solid but could be modernized with enhanced security and privacy features.
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.
