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

Autohaus Ostmann GmbH & Co. KG is a well-established automotive dealership group operating in the Nordhessen region of Germany, with over 60 years of experience. The company offers a broad portfolio of vehicles from Volkswagen, Volkswagen Nutzfahrzeuge, Audi, SEAT, CUPRA, ŠKODA, and MAXUS, serving both retail and commercial customers. Their services include new and used vehicle sales, servicing, repairs, parts, and fleet management, positioning them as a comprehensive automotive service provider in their regional market. The website reflects a professional and consistent brand presence aligned with Volkswagen's corporate identity. Technically, the website is built on a modern React framework integrated with Volkswagen's proprietary CMS platform, leveraging Adobe Helix RUM for performance monitoring. The site is mobile-optimized and SEO-friendly, with structured data enhancing search engine visibility. Hosting and asset delivery are managed within Volkswagen's corporate infrastructure, ensuring reliability and security. From a security perspective, the site enforces HTTPS with strong SSL configurations and implements key security headers. No critical vulnerabilities or exposed sensitive data were detected. Privacy and cookie policies are comprehensive and GDPR compliant, though explicit security policy and incident response information are not publicly detailed. The absence of a vulnerability disclosure policy suggests an area for improvement. Overall, the website demonstrates a strong digital maturity and security posture appropriate for a medium-sized automotive dealership. Strategic recommendations include publishing a dedicated security policy, enhancing incident response transparency, and adopting a vulnerability disclosure framework to further strengthen trust and compliance.

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

2 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.

    • 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

Business profile

Autohaus Ostmann holds a solid market position as a regional multi-brand automotive dealer with a diversified portfolio including passenger and commercial vehicles. Their business model focuses on direct sales, aftersales services, and fleet management, targeting both individual customers and commercial clients in the Kassel and Nordhessen regions. The company benefits from long-standing brand recognition and Volkswagen's corporate backing, which supports customer trust and operational stability. Revenue streams are likely diversified across vehicle sales, servicing, parts, and financing solutions. The partnership ecosystem is closely tied to Volkswagen and associated brands, with no evidence of external subsidiaries or parent companies. Growth indicators include multiple locations and a strong customer review rating. The company’s operations reflect a mature and stable business with opportunities to enhance digital engagement and security transparency.

Security posture

The website exhibits a mature security posture with enforced HTTPS, robust SSL configuration, and implementation of security headers such as HSTS, X-Content-Type-Options, and Content-Security-Policy. No exposed credentials or sensitive data were found in the HTML content. The use of Adobe Helix RUM indicates active performance and security monitoring. However, the absence of a publicly available security policy and incident response contact details limits transparency. There is no evidence of a vulnerability disclosure program or security.txt file, which are best practices for responsible vulnerability management. Compliance with GDPR is evident through comprehensive privacy and cookie policies. Overall, the security maturity is good but could be improved by formalizing and publishing security governance documents and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact information to facilitate reporting and handling of security incidents.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility compliance to improve usability for all users.
  5. Regularly review and audit third-party scripts and dependencies to mitigate potential vulnerabilities.

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.
