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

TÜV SÜD is a globally recognized enterprise specializing in safety, security, and sustainability solutions, with a rich history spanning over 150 years. The company offers a broad range of services including testing, inspection, certification, auditing, training, and technical advisory across multiple industries such as energy, transportation, manufacturing, real estate, and healthcare. Their market position is that of a trusted partner for businesses seeking compliance and quality assurance worldwide. Technically, the website is built on modern frameworks such as Next.js and integrates advanced consent management tools like OneTrust, alongside Adobe's digital marketing and analytics solutions. The site demonstrates good performance, mobile optimization, and accessibility, reflecting a mature digital infrastructure. From a security perspective, TÜV SÜD employs strong HTTPS encryption, comprehensive security headers, and cookie consent mechanisms, indicating a robust security posture. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a public vulnerability disclosure or security.txt file suggests room for improvement in transparency and incident response readiness. Overall, the website presents a low risk profile with strong trust indicators and professional content. The missing WHOIS data for the queried subdomain is a minor concern but likely a technical querying issue rather than a legitimacy problem. Strategic recommendations include enhancing public security disclosures, maintaining up-to-date third-party libraries, and improving incident response visibility.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. 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.

  3. 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.

Business context

Business profile

TÜV SÜD operates as an essential entity within the safety and certification industry, targeting a diverse set of sectors including energy, transportation, manufacturing, real estate, and healthcare. Their competitive advantage lies in their extensive history, global presence, and comprehensive service portfolio. Revenue streams are primarily service-based, including certification, testing, auditing, and advisory. The company targets industrial clients, manufacturers, and regulatory bodies, emphasizing compliance and sustainability. Growth indicators include recent revenue growth announcements and expansion of digital services. The partnership ecosystem includes technology providers and industry regulators, supporting TÜV SÜD's market leadership and innovation focus.

Security posture

The security maturity of TÜV SÜD's website is high, with enforced HTTPS, strong security headers, and cookie consent compliance. The site avoids common pitfalls such as exposed credentials or vulnerable libraries. Compliance with GDPR is evident through detailed privacy and cookie policies and consent management. However, the lack of a public vulnerability disclosure program and limited incident response contact information indicate potential gaps in transparency and readiness. Data protection officer contact is provided, supporting regulatory compliance. Overall, the security posture supports business continuity and customer trust but could benefit from enhanced public security communication.

Recommendations

  1. Implement a public vulnerability disclosure policy or security.txt file to improve transparency and encourage responsible reporting.
  2. Enhance incident response contact visibility by providing dedicated security or abuse email addresses prominently on the site.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Maintain and communicate clear data retention policies to strengthen privacy compliance and user trust.
  5. Invest in ongoing penetration testing and security assessments to proactively identify and remediate risks.

Technical notes

Notes

The website leverages a modern technology stack including React with Next.js framework, Adobe DTM for tag management, and OneTrust for consent management, indicating a high level of digital maturity. The CMS is Sitecore, which supports enterprise-grade content management. Performance is moderate with good mobile optimization and accessibility features. The site uses structured data (JSON-LD) and Open Graph tags effectively for SEO and social media integration. Technical risks are minimal, but continuous monitoring and updates are recommended to avoid technical debt and ensure optimal performance.
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.
