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

The website etat.public.lu serves as the official directory and portal for public administration websites of the Grand Duchy of Luxembourg. It provides comprehensive listings of ministries, administrations, public services, and related government portals. The site targets government agents, citizens, and professionals seeking official information and services. It also promotes Luxchat4Gov, a secure instant messaging platform for government employees. Technically, the site is built on Adobe Experience Manager, uses modern web standards, and is optimized for mobile and accessibility. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers could be improved. The absence of WHOIS data limits domain registration insights, but the site’s branding and content strongly indicate legitimacy as a government resource. Overall, the site is professional, trustworthy, and well maintained.

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

8 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

Etat.public.lu occupies a critical role as the official government portal aggregating public sector websites in Luxembourg. Its business model is informational and service-oriented, focusing on transparency and accessibility of government resources. The portal supports government communication and digital transformation initiatives, including secure internal messaging. The extensive network of linked government domains and ministries reflects a broad partnership ecosystem within the public sector. The site’s launch in 2020 aligns with modernization efforts. Its market position is authoritative within Luxembourg’s digital government landscape, serving as a central hub for citizens and officials alike.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent compliant with GDPR, and no visible exposure of sensitive data. However, the lack of explicit security headers such as Content-Security-Policy and absence of a published vulnerability disclosure or security.txt file indicate areas for improvement. No signs of vulnerabilities or malicious content were detected. Incident response contact information is not explicitly provided, which could hinder rapid reporting of security issues. Overall, the site maintains a secure environment appropriate for a government portal but could enhance transparency and defense-in-depth measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Add explicit contact information for security incidents to improve incident response readiness.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance monitoring and logging to detect and respond to potential security threats proactively.

Notes

The site is built on Adobe Experience Manager, a robust enterprise CMS platform, indicating a strong technical foundation. The use of modern HTML5, CSS, and JavaScript with SVG icons supports good accessibility and responsive design. Performance is moderate, with potential for optimization in asset delivery and caching. The site includes proper meta tags for SEO and social sharing (Open Graph and Twitter cards). No analytics or tracking scripts were detected, aligning with privacy best practices. Hosting details are not explicit but the site uses HTTPS with good SSL configuration. Overall, the technical infrastructure supports a professional and secure government web presence.
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.
