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

Crew Knüttel Motorsport GmbH & Co.KG is a specialized motorsport company based in Germany, established in 1984, providing racing tire services and support for various motorsport disciplines. The company maintains a professional online presence with a well-structured website offering detailed information about their services, team, and contact points. Their market position is that of a traditional, niche service provider in the motorsport sector, targeting racing teams and motorsport enthusiasts. Technically, the website employs modern web technologies including JavaScript libraries like Splide.js and jQuery, and is optimized for mobile devices with responsive design elements. However, there is room for improvement in accessibility and performance optimization. Security-wise, the site uses HTTPS but lacks visible security headers and formal security policies, which could be enhanced to improve trust and compliance. Privacy compliance is partially addressed with a privacy policy present but no cookie consent mechanism detected. Overall, the website is professional and trustworthy but could benefit from stronger security and privacy features.

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

7 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 company operates in the transportation sector with a focus on motorsport tire services, leveraging long-standing experience since 1984. Their business model centers on providing specialized racing tire services for brands like Michelin, Yokohama, and Nova. The presence of multiple physical locations and active social media channels indicates a stable operational footprint and engagement with their target audience. The lack of visible e-commerce or payment processing suggests a service-oriented rather than direct retail business model. Growth potential may be supported by their niche expertise and established reputation. Partnerships with tire manufacturers and a professional web agency (WebQ GmbH) indicate a solid partnership ecosystem.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposed sensitive data or vulnerable libraries. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security robustness. There is no published security policy or incident response contact, which limits transparency and preparedness for security incidents. No vulnerability disclosure or security.txt file is present, which is a missed opportunity for responsible vulnerability management. The site does not appear to collect sensitive user data on the homepage, reducing immediate risk, but improvements in security best practices and compliance are recommended.

Recommendations

  1. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  2. Add a cookie consent banner and mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish a clear security policy and provide incident response contact information to build trust and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to meet modern standards and improve user experience for all visitors.

Technical notes

Notes

The website is built with standard HTML5, CSS3, and JavaScript, utilizing libraries such as Splide.js for carousels and jQuery for DOM manipulation. The site is mobile responsive with breakpoints for different screen sizes, indicating good adaptation to mobile devices. Performance is moderate with no explicit indicators of slow loading but no advanced optimization techniques detected. No CMS or hosting provider information is evident from the HTML. The site lacks advanced SEO structured data like JSON-LD but uses Open Graph meta tags for social sharing. No analytics or tracking scripts are present, which may limit marketing insights but enhances privacy. Technical debt appears low with clean markup and no broken elements visible.
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.
