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

mobile.de GmbH operates a prominent online vehicle marketplace primarily serving the German market, targeting private users, commercial sellers, and dealers. The company provides vehicle listings and data access services, with a clear business presence in Berlin, Germany. However, the website content is currently inaccessible due to an access denied page likely triggered by automated access detection or a web application firewall (WAF), limiting direct content analysis. The technical infrastructure includes AWS DNS hosting and custom font usage, but lacks visible security headers or privacy policies on the analyzed page. The absence of analytics scripts and tracking pixels suggests minimal data collection on this particular page. The website branding is consistent, but the content quality and user experience are poor due to the access restriction. Security posture is weakly observable due to the blocked content, but the presence of a WAF indicates some level of security enforcement. No explicit vulnerabilities or compliance information is available. Overall, the site demonstrates legitimacy through consistent WHOIS data and company information but requires improved transparency and accessibility for automated analysis. Strategic recommendations include enhancing security header implementation, publishing clear privacy and cookie policies, and providing vulnerability disclosure and incident response contacts to improve 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

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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

  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 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';…

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

mobile.de holds a leading position in the German vehicle marketplace sector, leveraging an online platform to connect private users, commercial sellers, and dealers. The business model centers on facilitating vehicle transactions and data access, supported by a professional corporate structure with named managing directors and registered office in Berlin. The company likely generates revenue through listing fees, data services, and dealer partnerships. The absence of visible marketing or analytics tools on the blocked page limits insight into customer engagement strategies. The company’s ecosystem appears focused and specialized, with no detected subsidiaries or partner domains from the provided data.

Security posture

The current security posture is difficult to fully assess due to the access denied page blocking automated content retrieval. The presence of a WAF or similar security mechanism is confirmed, which helps protect against automated scraping and potential attacks. However, the lack of visible security headers and absence of published security policies or incident response contacts on the page are gaps. No evidence of exposed sensitive data or vulnerable libraries was found, but the security score is low due to limited observable data. Compliance with GDPR or other frameworks cannot be confirmed from the provided content.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  3. Provide a publicly accessible vulnerability disclosure policy and incident response contact information.
  4. Ensure HTTPS is enforced and clearly indicated on all pages.
  5. Improve website accessibility and SEO optimization to enhance user experience and discoverability.

Technical notes

Notes

The website uses AWS DNS hosting with multiple AWS nameservers, indicating a robust hosting infrastructure. Custom web fonts are loaded from a static classistatic.de domain. No CMS or common web frameworks were detected in the provided HTML snippet. The page is minimal and serves as an access denied message, limiting technical assessment. No analytics or marketing scripts were found. Performance and mobile optimization cannot be assessed from the blocked content. The lack of meta tags and SEO elements on this page suggests a need for improvement in technical SEO and metadata management.
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.
