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

Automobile Tierhold GmbH is a well-established family-owned automobile dealership based in Germany since 1981. The company specializes in selling new vehicles from Kia, Volvo, and Mazda brands, alongside a large inventory of over 600 certified used cars. Their service offerings include vehicle maintenance, tire changes, smart repair, and e-mobility solutions, targeting both private customers and commercial clients. The website reflects a professional and consistent brand image with clear navigation and comprehensive service information. Technically, the website employs modern web technologies such as Bootstrap and jQuery, with integration of Matomo analytics for user behavior tracking. The site is mobile-optimized and provides a cookie consent mechanism aligned with GDPR requirements. However, there is room for improvement in security headers and accessibility features. The absence of WHOIS data for the domain is a notable anomaly that slightly impacts trustworthiness. From a security perspective, the site uses HTTPS and has implemented cookie consent, but lacks visible HTTP security headers and explicit incident response contacts. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is well addressed with a comprehensive privacy policy and cookie management. Overall, the website presents a trustworthy and professional front for the business, though the missing WHOIS data and minor security header gaps suggest areas for enhancement. Strategic recommendations include improving HTTP security headers, maintaining up-to-date libraries, and establishing clear incident response contacts to bolster security posture and trust.

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. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Automobile Tierhold GmbH operates in the regional German automobile retail and service market, leveraging strong partnerships with major brands like Kia, Volvo, and Mazda. Their competitive advantage lies in their long-standing family business reputation, extensive used car inventory, and comprehensive service offerings including e-mobility. Revenue streams primarily come from new and used car sales, service and maintenance, and accessory sales. The company targets both private individuals and commercial customers, with a focus on quality and transparent customer service. Their digital presence supports growth through online service booking and active social media engagement. The partnership ecosystem includes official brand dealerships and local service providers, enhancing market reach and customer trust.

Security posture

The current security maturity level of the website is moderate. HTTPS is enforced, and cookie consent mechanisms are in place, demonstrating awareness of privacy and security best practices. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates potential exposure to common web vulnerabilities. No direct evidence of vulnerabilities or data leaks was found in the HTML content. Compliance with GDPR is evident through privacy policies and cookie management. Incident response readiness is not explicitly addressed, which could delay mitigation in case of security incidents. Overall, the security culture appears basic but functional, with opportunities for strengthening through enhanced technical controls and documented security policies.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Establish and publish an incident response policy and contact information to improve readiness and transparency.
  3. Regularly update all JavaScript libraries and dependencies to the latest secure versions to reduce vulnerability risks.
  4. Enhance website accessibility features to comply with standards and improve user experience for all visitors.
  5. Conduct periodic security audits and penetration testing to proactively identify and remediate security gaps.

Technical notes

Notes

The website is built using a combination of Bootstrap for responsive design and jQuery for interactivity, supplemented by FontAwesome icons and custom JavaScript. It integrates Matomo analytics for privacy-conscious user tracking. The site loads multiple CSS and JS assets deferred to optimize performance. Mobile optimization is good, with responsive images and layouts. SEO is supported by proper meta tags and structured navigation. However, no CMS or hosting provider information is evident, and no advanced frameworks like React or Angular are detected. Performance is moderate, with potential improvements in caching and asset minification. The absence of security headers and limited accessibility features highlight areas for technical modernization to enhance security and compliance.
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.
