The website targets passengers and travelers within Luxembourg and Europe, positioning itself as a key player in public transportation with international connections. Technically, the site employs modern web technologies including Bootstrap, FontAwesome, Google Tag Manager, and Matomo analytics, delivering a responsive and accessible user experience with good SEO practices. Security posture is strong with HTTPS enforced and secure form handling, though explicit security headers and policies are absent.

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

6 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

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

  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

CFL operates in the transportation sector, focusing on passenger rail services and mobility solutions. Its business model revolves around providing travel information, ticketing services, and innovative mobility options like carsharing and secure bike parking. The company maintains partnerships with international ticketing platforms and operates subsidiaries for freight and group services. The website content and linked domains indicate a mature organization with a broad service offering and a strong market position in Luxembourg. Growth indicators include digital ticket sales and mobility innovations. The partnership ecosystem with European travel platforms enhances its competitive advantage and customer reach.

Security posture

The website demonstrates a solid security foundation with HTTPS and secure handling of user inputs in forms. Analytics are implemented with user consent mechanisms implied by cookie usage. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts represent gaps in transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is not explicitly documented, and no vulnerability disclosure or security.txt files were found, indicating room for improvement in security governance and incident readiness.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to enhance GDPR compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen browser security.
  3. Publish a security policy and incident response contact information to improve transparency and preparedness.
  4. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Regularly review and update WHOIS information to ensure domain registration transparency and trustworthiness.

Technical notes

Notes

The website uses a modern tech stack with Bootstrap for responsive design, FontAwesome for icons, and integrates Google Tag Manager and Matomo for analytics. The site is mobile-optimized and accessible, with structured navigation and interactive forms for travel searches and bookings. Performance is moderate with room for optimization. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site uses SVG icons and custom scripts for enhanced UI elements. Technical debt appears low, but adding security headers and improving privacy disclosures would enhance the technical maturity.
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.
