70/100

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

CFL is the national railway company of Luxembourg, providing passenger and freight transport services along with mobility solutions such as carsharing, bicycles, tram, and funicular. The website serves as a comprehensive travel portal offering timetable searches, ticket bookings (both national and international), travel packages, and customer services. The company holds a strong market position in Luxembourg's transportation sector with a large operational scale and multiple subsidiaries. Technically, the website employs modern frameworks like Bootstrap and FontAwesome, integrates Google Tag Manager and Matomo for analytics, and is optimized for mobile and accessibility. Security posture is strong with HTTPS, security headers, and no visible vulnerabilities, though explicit security policies and incident response contacts are not found. Privacy compliance is good with privacy and cookie policies and consent mechanisms in place. Overall, the website is professional, trustworthy, and user-friendly, though the lack of WHOIS data slightly reduces trustworthiness from a domain registration perspective.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

No critical or high findings in the checks that completed. These medium findings are worth fixing next.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Medium

      DMARC not enforcing

      DMARC policy is set to "none"

      What to do: Gradually move to "quarantine" then "reject" policy

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

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

  • SSL/TLS: did not complete in this scan.
  • Security headers: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • Network security: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 primarily in the transportation sector, focusing on passenger rail services and freight logistics. Its business model includes direct ticket sales, mobility solutions, and travel packages, targeting passengers in Luxembourg and neighboring European countries. The company leverages partnerships with international ticketing platforms and maintains subsidiaries for freight and group operations. The website's multilingual support and comprehensive service offerings indicate a mature digital presence aimed at enhancing customer experience and expanding market reach. CFL's strategic partnerships and diversified services position it competitively within the European rail transport market.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and secure handling of user inputs in forms. Analytics are implemented responsibly with user consent mechanisms. However, the absence of a publicly accessible security policy or incident response contact limits transparency and readiness communication. No vulnerabilities or exposed sensitive data were detected in the analyzed content. To improve, CFL should consider publishing explicit security policies and a vulnerability disclosure program to enhance trust and compliance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact information for security issues.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance WHOIS data visibility or verify domain registration details for trust.
  5. Continue maintaining and updating privacy and cookie consent mechanisms.

Technical notes

Notes

The website uses a modern tech stack including Bootstrap for responsive design, FontAwesome for icons, and JavaScript libraries like jQuery and SVG4Everybody for compatibility. Analytics are managed via Google Tag Manager and Matomo, indicating a balanced approach to data collection and privacy. The site is mobile-optimized with good accessibility features such as skip links and ARIA labels. Performance is moderate with room for optimization. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Overall, the technical implementation supports a professional and user-friendly experience with scope for minor improvements in performance and security transparency.
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.
