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

1 finding rated critical or high. Fix these first.

  1. 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

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

Stadler operates in the transportation sector with a focus on rail vehicle manufacturing and signalling technology. The company maintains a large operational scale with over 15,000 employees and significant order backlog and revenue figures. Its business model centers on manufacturing high-quality rail vehicles tailored to customer needs and providing ongoing service and signalling solutions. The company has a strong market position supported by certifications such as ISO 27001 and a comprehensive compliance framework. The website's content and social media presence indicate active engagement with customers and stakeholders. The lack of WHOIS transparency is a minor concern but does not detract from the company's established reputation.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented. Cookie consent is managed via Cookiebot, ensuring GDPR compliance. The use of Matomo analytics indicates privacy-conscious tracking. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public vulnerability disclosure or security.txt file and lack of explicit incident response contact details suggest areas for improvement. Overall, the security maturity is good, supporting business continuity and data protection obligations.

Recommendations

  1. Publish a security.txt file or vulnerability disclosure policy to enhance transparency and trust.
  2. Provide explicit incident response contact information to facilitate security communication.
  3. Regularly review and update third-party scripts and analytics tools to mitigate vulnerabilities.
  4. Enhance accessibility features to improve inclusivity and compliance with standards.
  5. Maintain and renew security certifications and compliance frameworks to demonstrate ongoing commitment.

Technical notes

Notes

The website is built on a modern tech stack including React and Next.js, supported by the Storyblok CMS. It integrates Matomo for analytics and Cookiebot for cookie consent management, reflecting a focus on privacy and compliance. The site loads multiple optimized assets and fonts, indicating attention to performance. Mobile optimization and accessibility are well addressed. The absence of hosting provider details limits full infrastructure assessment. Overall, the technical implementation is robust, supporting a professional and scalable digital presence.
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.
