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

The Geoportal of the Grand-Duchy of Luxembourg is an official governmental platform providing comprehensive geospatial data, maps, and related services to individuals, professionals, and developers. It serves as the national authoritative source for geodata across multiple sectors including environment, energy, tourism, spatial planning, and agriculture. The platform offers a variety of applications and catalogues, supporting both public and professional users with tools such as 3D printing exports, coordinate conversion, and route planning. The website is well-branded, consistent, and targets a broad audience with multilingual support. Technically, the site employs modern web technologies including jQuery, Modernizr, and SVG icons, and integrates Piwik (Matomo) for analytics. It is mobile-optimized and accessible, with good SEO practices. The site uses HTTPS with strong SSL configuration, although explicit security headers are not detected. Some services require strong authentication, indicating attention to security for sensitive operations. Security posture is solid with no visible vulnerabilities or exposed sensitive data, but the absence of a published security policy or vulnerability disclosure limits transparency. Privacy compliance is partial; while terms and conditions and a privacy policy page exist, no cookie consent mechanism is evident. Contact information is limited to a contact form with no direct emails or phone numbers visible. Overall, the site is trustworthy, professionally maintained, and aligned with its governmental role. Strategic improvements in security transparency and privacy compliance would enhance its posture further.

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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 Geoportal is positioned as Luxembourg's official governmental geospatial data provider, serving a diverse audience including individuals, professionals, and developers. Its competitive advantage lies in authoritative data, comprehensive sector coverage, and integration with government services such as cadastral extracts and spatial planning. The business model is service-oriented, focusing on public data dissemination and professional tools. Revenue streams likely stem from governmental funding and possibly fees for certain extract orders. The platform demonstrates growth through new application releases and updates, and maintains partnerships with government entities like ACT and DAC. The multilingual approach and broad sector coverage support wide adoption and strategic national importance.

Security posture

The website exhibits a mature security posture with enforced HTTPS, no visible sensitive data leaks, and use of strong authentication for critical services. However, the lack of explicit security headers and absence of a public security policy or vulnerability disclosure program represent gaps. Privacy compliance is limited by missing cookie consent mechanisms and no clear GDPR compliance indicators. Incident response contact channels are not disclosed. Overall, the site is secure for general use but could improve transparency and compliance to meet higher standards.

Recommendations

  1. Implement and publish a comprehensive security policy page detailing security practices and incident response.
  2. Add HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  3. Deploy a cookie consent banner to comply with GDPR and inform users about tracking.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance contact information availability including security and privacy contacts to improve trust and compliance.

Technical notes

Notes

The website uses a stable and somewhat dated technology stack with jQuery 1.10.1 and Modernizr 2.6.2, indicating potential for modernization. It employs responsive design and accessibility best practices, with good SEO metadata and Open Graph tags. Analytics are handled via Piwik (Matomo), a privacy-friendly alternative to Google Analytics. Hosting details are not explicit, but domain name servers indicate government infrastructure. Performance is moderate with no evident blocking scripts or heavy resources. The site could benefit from updating libraries and adding modern frameworks to improve maintainability and security.
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.
