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

The Geoportal of the Grand-Duchy of Luxembourg is an official governmental platform managed by the Administration du Cadastre et de la Topographie (ACT). It provides comprehensive geospatial data, maps, and related applications targeting individuals, professionals, and developers. The platform serves as the authoritative source for cadastral, environmental, energy, tourism, and spatial planning data within Luxembourg. The website is well-branded with consistent government logos and multilingual support, reflecting its national scope and official status. Technically, the site employs a moderate technology stack including jQuery, Modernizr, and Piwik analytics. It is hosted on government-related infrastructure with Luxembourg-based name servers. The site is responsive and accessible, with good SEO practices and clear navigation. However, some modern security headers are not visibly implemented, and explicit privacy and cookie policies are limited or absent. From a security perspective, the site uses HTTPS and plans to enforce strong authentication for sensitive services such as cadastral extract ordering. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a vulnerability disclosure policy and incident response contacts suggests room for improvement in security transparency. Overall, the geoportal is a trustworthy, professional government resource with a solid business and technical foundation. Strategic enhancements in privacy compliance, security headers, and incident response documentation would further strengthen its security posture and user trust.

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.

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"

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 occupies a key position as Luxembourg's national platform for geospatial data, operated by the ACT government agency. Its business model is service-oriented, providing free and professional access to geodata and related applications. The platform supports multiple sectors including government, energy, environment, real estate, and transportation. Its target customers range from individual citizens to professional surveyors and developers. The presence of multilingual content and extensive map catalogues indicates a mature offering with broad reach. Partnerships with ACT and other government entities reinforce its authoritative status. The platform's growth is indicated by ongoing updates such as the new cadastral extract tool requiring strong authentication. The lack of commercial advertising or affiliate programs aligns with its public service mission.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used throughout, and strong authentication is planned for sensitive services. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No direct contact channels for security incidents or vulnerability disclosures are provided, limiting incident response readiness. The use of Piwik analytics suggests moderate user tracking but no excessive data collection. No exposed credentials or sensitive data were found in the HTML. Overall, the site follows basic security best practices but would benefit from enhanced security headers, documented incident response procedures, and explicit privacy and cookie policies to improve compliance and user trust.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers such as Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure policy and provide clear incident response contact information to improve security transparency and readiness.
  4. Enhance user tracking transparency by detailing analytics data collection and retention policies.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a traditional but stable technology stack including jQuery 1.10.1 and Modernizr 2.6.2, which are somewhat dated but functional. Piwik analytics is used for tracking, indicating a preference for open-source analytics solutions. The site is hosted on government infrastructure with Luxembourg-based name servers, ensuring geographic and organizational alignment. The HTML structure is valid and includes responsive design meta tags, supporting good mobile optimization. However, the absence of modern JavaScript frameworks or CMS identification suggests a custom or legacy platform. Performance is moderate with no explicit indicators of optimization or CDN usage. Accessibility features such as skip links and ARIA roles are present, reflecting attention to inclusive design. SEO is supported by meta tags and Open Graph data. Overall, the technical implementation is solid but could benefit from modernization and enhanced security configurations.
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.
