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

CYBERSECURITY Luxembourg operates as the national cybersecurity portal for Luxembourg, providing a centralized platform for cybersecurity news, ecosystem engagement, events, educational resources, and community support. The portal targets a broad audience including cybersecurity professionals, public institutions, private companies, startups, and the general public interested in cybersecurity within Luxembourg. It is positioned as a government-affiliated authoritative source, promoting collaboration and awareness in the national cybersecurity ecosystem. Technically, the website is built using modern web technologies such as React, Bootstrap, and Leaflet.js, with Font Awesome icons and Matomo analytics integrated for tracking. The site demonstrates good mobile optimization and user experience, with clear navigation and professional design. Performance is moderate, and accessibility features are basic but present. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers and does not provide visible privacy or cookie policies, nor incident response or vulnerability disclosure information. Matomo analytics is used without a visible cookie consent mechanism, indicating partial privacy compliance. The WHOIS data shows consistent domain registration aligned with the website's government and cybersecurity focus, supporting legitimacy. Overall, the website is a credible and professional government portal with good content and technical implementation but requires improvements in privacy compliance, security headers, and transparency regarding incident response and vulnerability disclosure to enhance trust and 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

  3. 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
      • ASVS V12.1.1

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 portal serves as a central hub for Luxembourg's cybersecurity ecosystem, fostering collaboration among government entities, private sector companies, startups, and the wider community. Its business model is informational and community-driven, supported by government patronage. The platform offers visibility to ecosystem members and organizes events and initiatives to strengthen national cybersecurity capabilities. The presence of ecosystem dashboards and startup support indicates a strategic focus on growth and innovation. Partnerships with government domains and cybersecurity organizations enhance its market position. The portal's content and services align with national cybersecurity priorities, targeting professionals and institutions involved in securing Luxembourg's digital infrastructure.

Security posture

The website demonstrates a baseline security posture with enforced HTTPS and no visible exposure of sensitive information. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense-in-depth. The lack of published privacy and cookie policies, as well as incident response contacts or vulnerability disclosure mechanisms, indicates gaps in compliance and transparency. Use of Matomo analytics without explicit consent mechanisms may raise privacy concerns under GDPR. No known vulnerabilities or malicious content were detected. Overall, the security maturity is moderate but would benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Add a cookie consent banner to inform users and obtain consent for tracking technologies.
  3. Deploy security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  4. Provide clear incident response contact information and establish a vulnerability disclosure policy or security.txt file.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

Technical notes

Notes

The website is built on a modern React framework with Bootstrap for responsive design and Leaflet.js for mapping functionalities. Font Awesome 6 is used extensively for icons. Analytics are handled by Matomo, a privacy-focused alternative to Google Analytics, though lacking explicit consent mechanisms. The site loads external scripts asynchronously to optimize performance. The HTML structure is valid and well-organized, supporting good navigation and mobile responsiveness. However, there is room for improvement in accessibility compliance and SEO metadata completeness. Hosting details are not explicitly provided, but domain name servers indicate EuroDNS, a reputable DNS provider. Overall, the technical infrastructure is solid with opportunities for modernization in security and privacy implementations.
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.
