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

AutoScout24.ch is a prominent Swiss online automotive marketplace specializing in vehicle listings for buyers and sellers within Switzerland. The platform is part of the Scout24 AG group, a well-known entity in digital marketplaces. However, the website content is currently inaccessible due to a Cloudflare Web Application Firewall (WAF) security challenge, which limits the ability to fully analyze the site’s content, policies, and security posture. The technical infrastructure employs modern web technologies such as React and Next.js, indicating a contemporary digital maturity level. Despite the blocking, WHOIS data confirms the domain's legitimacy and consistency with the business claims. The security posture cannot be fully assessed due to the WAF, but the presence of Cloudflare suggests baseline protection. Privacy and cookie policies, as well as contact information, are not accessible, which may impact compliance assessments. Overall, the site appears to be a safe and legitimate business platform, but full evaluation requires bypassing the WAF challenge.

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

      • 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 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

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 large-scale online marketplace focused on the transportation sector, specifically automotive sales in Switzerland. Its business model revolves around connecting private sellers and dealers with buyers through a digital platform. The company benefits from its association with Scout24 AG, enhancing its market position and credibility. The platform targets individual consumers and businesses interested in vehicle transactions. While the site is professionally built with modern frameworks, the current WAF challenge restricts visibility into user engagement features, marketing tools, and detailed business operations. No direct partnerships or subsidiaries beyond the parent company were identified in the accessible data. The lack of visible privacy and security policies may be an area for improvement to strengthen trust and regulatory compliance.

Security posture

The website is protected by Cloudflare’s WAF, which currently blocks direct access and presents a Turnstile captcha challenge. This indicates a proactive security measure to mitigate automated attacks and abuse. However, this also limits the ability to analyze security headers, SSL/TLS configuration, and potential vulnerabilities. No security policies or incident response contacts are publicly accessible. The absence of exposed sensitive data or known vulnerabilities is positive, but the lack of visible compliance documentation and contact channels for security incidents is a gap. The security score is low due to limited visibility but the use of Cloudflare suggests a baseline security posture. Recommendations include publishing clear security policies, incident response procedures, and ensuring compliance with GDPR and other relevant regulations.

Recommendations

  1. Implement a user-friendly and accessible privacy and cookie policy page to enhance compliance and user trust.
  2. Publish clear terms of service and security policy documents accessible without WAF challenge.
  3. Provide visible contact information including security incident response contacts (e.g., security@ or abuse@ emails).
  4. Review and optimize WAF settings to balance security with accessibility for legitimate users and analysts.
  5. Enhance transparency by adding certifications or trust badges related to data protection and security.

Technical notes

Notes

The website employs a modern technology stack including React and Next.js frameworks, indicating a server-side rendered React application optimized for performance and SEO. Hosting and security are managed via Cloudflare, providing CDN, DDoS protection, and WAF capabilities. The presence of Cloudflare Turnstile captcha suggests advanced bot mitigation. However, the WAF challenge currently restricts content access, impacting performance and user experience assessments. No CMS or third-party marketing/analytics tools were detectable due to content blocking. The site uses embedded custom fonts and global CSS variables for consistent theming. Technical debt or outdated components could not be assessed. Recommendations include ensuring WAF does not impede legitimate traffic and improving accessibility and SEO metadata visibility.
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.
