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

The website www.vdl.lu is the official digital presence of the Administration communale de la Ville de Luxembourg, serving as the primary portal for municipal information and services. It targets residents, visitors, and businesses in Luxembourg City, offering comprehensive content on city governance, administrative procedures, mobility, cultural events, and community engagement. The site is well-branded with consistent official logos and provides clear contact channels including email, phone, and social media links. Technically, the site is built on Drupal 9, leveraging modern web technologies and integrating Matomo for analytics and CookieYes for consent management. The site demonstrates good mobile optimization, accessibility, and SEO practices. Security is robust with HTTPS enforced and appropriate security headers, although no explicit security policy or incident response information is published. From a security and privacy perspective, the site implements a comprehensive cookie consent mechanism aligned with GDPR requirements, and no vulnerabilities or exposed sensitive data were detected. However, the absence of WHOIS data due to registry restrictions limits domain trust verification. Overall, the site presents a low risk profile with strong compliance and professional standards. Strategically, the site should consider publishing a dedicated security policy and incident response contacts to enhance transparency and trust. Additionally, implementing a vulnerability disclosure policy or security.txt file would further strengthen its security posture.

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

5 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

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025

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 City of Luxembourg's official website positions itself as a central hub for municipal services and information, catering to a diverse audience including residents, businesses, and tourists. Its business model is that of a government service portal, focusing on transparency, accessibility, and community engagement. The site supports various sectors such as urban development, social services, transportation, culture, and commerce. The presence of partner links like the Luxembourg City Tourist Office indicates a collaborative ecosystem. The site’s comprehensive content and digital maturity reflect a commitment to modern public service delivery and citizen engagement.

Security posture

The website exhibits a mature security posture with enforced HTTPS, modern security headers, and secure cookie management. The use of Cloudflare and F5 security cookies suggests protection against common web threats. The cookie consent mechanism is well-implemented, supporting GDPR compliance. However, the lack of a published security policy or incident response contact reduces transparency. No vulnerabilities or outdated libraries were detected in the analyzed content. The site would benefit from publishing explicit security documentation and a vulnerability disclosure policy to improve incident handling readiness and user trust.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including security and abuse email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by linking privacy and security policies prominently on the homepage.

Technical notes

Notes

The website is powered by Drupal 9, a modern and widely supported CMS, ensuring a solid foundation for content management and security. Integration with Matomo analytics and CookieYes consent management indicates a focus on privacy-aware data collection. The site uses external services like ReadSpeaker for accessibility enhancements. Performance is moderate, with good mobile responsiveness and accessibility features. The presence of security headers and HTTPS indicates a secure hosting environment, though the hosting provider is not explicitly identified. The site’s technical infrastructure supports a professional and user-friendly experience but could improve by disclosing hosting and security details.
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.
