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

  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 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';…
  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

AutoScout24 operates as a leading online marketplace connecting vehicle buyers and sellers across Europe, leveraging a large inventory of over 2.5 million listings. Its business model centers on providing a digital platform for both private individuals and dealers, generating revenue likely through advertising, premium listings, and dealer services. The company targets a broad audience including individual consumers seeking used or new vehicles and professional dealers. The presence of multiple country-specific domains and language localizations indicates a mature international footprint. Partnerships with major social login providers and integration with marketing and analytics platforms demonstrate a sophisticated digital ecosystem. The company benefits from strong brand recognition and consistent branding across markets, supported by a large parent company, Scout24 AG.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, use of reCaptcha Enterprise to mitigate automated abuse, and a consent banner ensuring GDPR compliance. Security headers are likely implemented though not explicitly visible in the HTML snapshot. No exposed sensitive data or vulnerable libraries were detected in the source. However, the absence of publicly available security policies, incident response procedures, and vulnerability disclosure mechanisms limits transparency. No direct security contact channels such as security@ or abuse@ emails were found. The site would benefit from publishing these details to enhance trust and preparedness. Overall, the security measures in place are appropriate for the business type, but documentation and communication could be improved.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  3. Enhance accessibility compliance to meet WCAG standards and improve user inclusivity.
  4. Regularly audit and update third-party scripts and tracking tools to minimize security risks.
  5. Provide explicit security contact channels for reporting incidents or vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack including React for frontend rendering, service workers for offline capabilities, and integrates multiple third-party analytics and marketing tools such as Google Tag Manager, Bing Ads, and Facebook Pixel. The site is mobile optimized with responsive design and includes accessibility features, though these could be further enhanced. Performance is moderate with asynchronous loading of scripts and deferred JavaScript. The absence of a common CMS suggests a custom or proprietary platform tailored for the automotive marketplace. Technical debt appears low, but continuous monitoring of third-party dependencies is recommended to avoid vulnerabilities. SEO is well addressed with proper meta tags and structured data. Overall, the technical infrastructure supports a robust and scalable user experience.
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.
