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

AutoScout24.ch is a leading online automotive marketplace in Switzerland, offering vehicle listings for buyers and sellers. The platform is part of Scout24 AG, a reputable company in the digital classifieds sector. The website employs modern web technologies such as React and Next.js and is protected by Cloudflare's security services, including Turnstile captcha, indicating a strong focus on security and bot mitigation. However, the current content is inaccessible due to the Cloudflare WAF challenge, limiting the ability to fully assess the website's content, privacy policies, and user experience. WHOIS data confirms the domain's legitimacy and consistency with the business claims. Overall, the website appears to be a professional and established platform in the transportation sector, but the security challenge page restricts comprehensive analysis.

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

9 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

  2. GDPR outside view

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

    • 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

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 an essential player in the Swiss automotive marketplace, targeting individuals and businesses interested in buying and selling vehicles. Its business model revolves around providing a digital platform for vehicle listings, leveraging a strong brand presence under Scout24 AG. The company benefits from a large user base and a well-established market position. The lack of visible privacy and cookie policies in the accessible content is a gap that should be addressed to enhance compliance and user trust. The platform's partnership ecosystem and subsidiary relationships are not explicitly detailed in the accessible data, but the parent company is known for digital classifieds. Growth indicators and revenue streams likely stem from listing fees, advertising, and dealer partnerships.

Security posture

The website benefits from Cloudflare's WAF and Turnstile captcha, providing robust protection against automated threats and DDoS attacks. However, the security headers and SSL/TLS configuration details are not visible due to the content being blocked. No explicit vulnerabilities or exposed sensitive data were detected in the accessible content. The absence of visible privacy policies, incident response contacts, and vulnerability disclosure mechanisms indicates areas for improvement in compliance and transparency. The security posture is strong in terms of perimeter defense but lacks visible internal security governance documentation.

Recommendations

  1. Implement and publicly display comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Provide clear contact information including security incident response channels such as abuse@ or security@ email addresses.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance transparency by including terms of service and data protection officer contact details on the website.
  5. Regularly audit and publish security headers and SSL/TLS configurations to demonstrate adherence to best practices.
Site observations

Automated reading of the public site. Ratings are indicative.

Cloudflare detected. The website content is blocked by a Cloudflare security challenge page with Turnstile captcha, indicating WAF protection is active. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Technical notes

Notes

The website uses a modern technology stack including React and Next.js frameworks, combined with Chakra UI for styling. Hosting and security are managed via Cloudflare, which provides CDN, WAF, and bot mitigation services. The presence of Cloudflare Turnstile captcha indicates advanced bot protection. However, the WAF challenge page currently blocks access to the main content, preventing a full evaluation of performance, SEO, accessibility, and mobile optimization. The technical infrastructure appears modern and scalable but requires configuration adjustments to reduce user friction caused by security challenges.
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.
