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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

GOVCERT.LU occupies a critical niche as Luxembourg's national CSIRT, focusing on cybersecurity incident response for government and critical sectors. Its business model is service-oriented, emphasizing incident coordination and information dissemination rather than commercial revenue. The organization maintains a clear partnership ecosystem through social media and open-source presence but lacks visible commercial partnerships or subsidiaries. Growth indicators include regular security announcements and active engagement with constituency. The site’s market position is authoritative within the government cybersecurity domain, with a focus on resilience and collective responsibility.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure incident reporting forms, and provision of PGP keys for secure communication. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the content. The lack of a published vulnerability disclosure policy or security.txt file limits transparency for external security researchers. Compliance with GDPR is indicated by the presence of a comprehensive privacy policy, but cookie consent mechanisms are missing. Incident response readiness is evident through clear reporting channels and timely announcements.

Recommendations

  1. Implement and publish a cookie policy with explicit user consent mechanisms to enhance privacy compliance.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen security posture.
  3. Publish a formal vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve transparency.
  4. Include explicit contact information for a Data Protection Officer to align with GDPR requirements and improve trust.
  5. Maintain and expand social media and community engagement to reinforce GOVCERT.LU’s authoritative position and outreach.

Technical notes

Notes

The website is built on the Hugo static site generator, leveraging modern web technologies such as SVG graphics, CSS, and JavaScript for interactivity. The site demonstrates fast loading times and excellent mobile responsiveness. SEO and accessibility features are well implemented, with clear navigation and structured content. Hosting details are not explicitly identified, but the use of cdn.public.lu for assets suggests government-managed infrastructure. There is no evidence of third-party analytics or tracking services, reflecting a privacy-conscious design. Technical risks are minimal, though the absence of some security headers and cookie consent mechanisms represent areas for modernization.
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.
