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

10 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

  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
    • 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

Luxembourg Airport holds a significant position in the regional transportation sector, leveraging its strategic location in Europe. Its business model focuses on passenger and cargo air transport complemented by ancillary services such as parking, retail, and VIP assistance. The airport's sustainability certification (ACI CO2 Neutral) enhances its market appeal. The website content and social media channels indicate active engagement with travelers and stakeholders. The absence of direct contact details on the homepage suggests a structured approach to customer service via dedicated pages. The airport is operated by Société de l’Aéroport de Luxembourg, indicating a formal corporate structure. The digital ecosystem includes partnerships with analytics and marketing platforms, supporting data-driven operations and customer insights.

Security posture

The website employs HTTPS with a valid SSL configuration, ensuring encrypted communications. Cookie consent mechanisms comply with GDPR, and accessibility tools are integrated to support diverse users. Use of security libraries like DOMPurify reduces XSS risks. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No security policy or incident response contact information is published, which could hinder timely vulnerability reporting and response. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be enhanced by adopting additional headers and publishing security policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  2. Publish a clear security policy and provide incident response contact channels to facilitate vulnerability reporting.
  3. Establish a vulnerability disclosure program or security.txt file to improve transparency and trust.
  4. Enhance homepage with clear company contact information to improve business credibility and user trust.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is built on WordPress CMS using modern plugins such as Kadence Blocks for layout and Reno AI Concierge for chatbot functionality. It integrates Google Tag Manager and Hotjar for analytics and user behavior tracking. Accessibility is enhanced via the UserWay widget. The site uses CDN services like Cloudflare and jsDelivr for performance optimization. The presence of cookie control scripts indicates compliance with privacy regulations. Performance is moderate with preloading of key images and asynchronous loading of scripts. The site is mobile optimized and SEO friendly with proper meta tags and structured data (JSON-LD). Technical risks include reliance on multiple third-party scripts and absence of some security headers. Hosting provider details are not explicitly found.
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.
