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

TÜV KNOW-HOW CLUB, operated under the TÜV Hessen brand, provides specialized training and informational events primarily targeting management system representatives and TÜV PROFiCERT customers. The website serves as a platform to promote membership, events, and certification-related services, positioning itself as a regional leader in certification education and networking. Technically, the site is built on TYPO3 CMS, hosted behind Cloudflare, and employs standard web technologies including Bootstrap and FontAwesome. While the site includes a GDPR-compliant cookie consent mechanism and valid SSL certificates, performance is suboptimal with high load times and no advanced security headers or DNSSEC enabled. Social media integration and legal compliance pages are present, enhancing trust. However, no explicit security policy or incident response information is provided, indicating room for maturity in security posture. Overall, the site is professional and trustworthy but would benefit from technical and security enhancements.

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. 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The TÜV KNOW-HOW CLUB operates in the certification and training sector, focusing on B2B services for companies requiring management system certifications. Its competitive advantage lies in its affiliation with TÜV Hessen and TÜV PROFiCERT, providing recognized certifications and networking opportunities. Revenue streams likely include membership fees, event participation, and certification services. The target customers are management representatives and certified clients seeking continuous education. The partnership ecosystem includes PROFiCERT and TÜV Hessen, reinforcing credibility. Growth indicators include a structured event offering and newsletter engagement. Strategic observations suggest leveraging digital channels more effectively and enhancing security transparency to build further trust.

Security posture

The website demonstrates a basic security posture with valid SSL certificates issued by Cloudflare and a GDPR-compliant cookie consent mechanism. However, it lacks critical security headers such as HSTS, CSP, and X-Frame-Options, and DNSSEC is not enabled, exposing it to potential DNS spoofing risks. No vulnerability disclosure or incident response information is available, which may hinder timely security issue reporting. The absence of a security.txt file and data protection officer contact details indicates limited transparency in security governance. The use of third-party tracking (etracker) is disclosed and managed via consent, aligning with privacy regulations. Overall, the security maturity is moderate but requires improvements to meet higher standards and regulatory expectations.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS.
  2. Implement essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Activate DNSSEC for the domain to enhance DNS integrity and prevent spoofing.
  4. Publish a security.txt file and provide clear incident response contact information to improve vulnerability management.
  5. Optimize website performance by reducing load times and resource sizes to enhance user experience and security.
Technical notes

Notes

The website is built on TYPO3 CMS, leveraging Cloudflare for hosting and SSL termination. It uses multiple CSS and JavaScript assets, including FontAwesome and Bootstrap components, to deliver a responsive and mobile-optimized experience. Despite this, the page load time is high (~21.9 seconds) with a large number of resources (97) and a page size of approximately 400KB, indicating potential inefficiencies. No advanced protocols or cipher suites are reported, and security headers are missing. The site lacks structured data (JSON-LD or Open Graph), which could improve SEO and content discoverability. The technical stack is solid but requires modernization and optimization to reduce technical debt and improve security and 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.
