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

7 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

  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 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 website operates as a government essential service in the emergency alert sector, leveraging partnerships within the Luxembourg government ecosystem. Its business model is service-oriented, focusing on public safety and information dissemination. The platform benefits from a strong trust position due to official backing and quality certifications such as Renow. The promotion of mobile apps indicates a multi-channel approach to reach the population effectively.

Security posture

The site employs HTTPS with strong SSL configuration and uses Cloudflare for DNS and CDN services, enhancing security and performance. Cookie consent mechanisms are implemented, reflecting GDPR compliance. However, explicit security policies, incident response contacts, and vulnerability disclosure information are not publicly available, representing areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis.

Recommendations

  1. Publish explicit security headers such as X-Frame-Options and X-Content-Type-Options to enhance browser security.
  2. Provide a publicly accessible security policy and incident response contact information to improve transparency and trust.
  3. Implement and disclose a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance contact information availability, including official emails and phone numbers for support and security incidents.
  5. Continue to monitor and update third-party libraries and tracking tools to minimize potential vulnerabilities.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, indicating a robust enterprise-level content management system. It uses modern web technologies including SVG icons, responsive design, and integrates Adobe Launch for tag management and analytics. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. Performance is moderate with room for optimization. Accessibility and SEO practices are good, supporting a wide audience including those with disabilities.
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.
