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

TÜV Rheinland is a global service provider specializing in testing, certification, inspection, consulting, and training services across multiple industries including transportation, energy, manufacturing, technology, healthcare, and telecommunications. The company holds recognized certifications such as ISO 9001, ISO 14001, and TISAX, positioning itself as a trusted leader in quality and safety services worldwide. The website supports multiple languages and regions, reflecting its extensive international presence. Technically, the website employs a variety of modern web technologies and marketing tools including jQuery, Google Tag Manager, Cookiebot for consent management, FullStory for session replay, and various advertising and analytics platforms. However, the site currently lacks a valid SSL certificate and does not support modern TLS protocols, which is a significant security concern. Performance is moderate with a page load time of approximately 4.3 seconds. From a security perspective, the site implements SPF records for email validation and has no subdomain takeover vulnerabilities. Nevertheless, the absence of HTTPS and security headers reduces the overall security posture. The site uses extensive tracking and marketing scripts with user consent managed via Cookiebot, indicating good privacy compliance practices. Contact information is primarily provided through a contact form, with no direct emails or phone numbers publicly listed. Overall, TÜV Rheinland's website reflects a mature business with strong market positioning and comprehensive service offerings. However, technical and security improvements, especially regarding SSL/TLS configuration and security headers, are recommended to enhance trust and protect user data.

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.

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

TÜV Rheinland operates as an essential entity in the global quality and safety services market, targeting businesses and organizations requiring testing, certification, and consulting. Its competitive advantage lies in its broad industry coverage, recognized certifications, and global footprint with 64 locations and 21 languages supported. The business model focuses on service delivery across multiple sectors including transportation, energy, manufacturing, and technology. Revenue streams likely derive from certification fees, consulting contracts, training programs, and inspection services. The company maintains a strong partnership ecosystem, including integration with SuccessFactors and other service providers. Growth indicators include active marketing campaigns, multilingual support, and extensive digital presence. Strategic observations highlight the need for enhanced security posture to maintain market trust and comply with evolving regulations.

Security posture

The current security maturity level of the TÜV Rheinland website is moderate but with critical gaps. The lack of a valid SSL certificate and disabled TLS protocols expose users to potential interception and downgrade attacks. While SPF records are correctly configured to prevent email spoofing, the absence of security headers such as HSTS, Content-Security-Policy, and X-Frame-Options weakens defense-in-depth. The website employs a comprehensive cookie consent mechanism via Cookiebot, ensuring GDPR compliance and user privacy preferences. No explicit incident response or vulnerability disclosure policies are found, which could hinder timely handling of security incidents. The extensive use of third-party tracking and marketing scripts increases the attack surface but is managed with user consent. Overall, the security culture appears privacy-aware but requires technical enhancements to mitigate risks effectively.

Recommendations

  1. Implement and maintain a valid SSL/TLS certificate supporting TLS 1.2 and TLS 1.3 protocols to secure all web traffic.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives to enforce HTTPS usage.
  3. Add essential security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to enhance protection against common web attacks.
  4. Establish and publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting and incident response.
  5. Review and minimize third-party tracking scripts to reduce attack surface and improve user privacy while maintaining marketing effectiveness.
Technical notes

Notes

The website uses a modern front-end stack including jQuery, Select2, FontAwesome, and SVG graphics for UI elements. It integrates multiple marketing and analytics tools such as Google Tag Manager, FullStory, LinkedIn Insight Tag, Microsoft UET, and Cookiebot for consent management. The site supports extensive localization with 64 locations and 21 languages. Performance metrics indicate moderate load times (~4.3 seconds) and a page size of approximately 949 KB, which is acceptable but could be optimized. Mobile optimization and accessibility are rated good based on responsive design and language selection features. However, the lack of a valid SSL certificate and disabled TLS protocols represent significant technical debt and security risk. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a robust user experience but requires security 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.
