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 a robust business model as an online automotive marketplace connecting buyers and sellers across Europe. Its market position is strong, supported by a large inventory and multi-country presence. The platform leverages partnerships with major social login providers and advertising networks to enhance user acquisition and engagement. Revenue streams likely include advertising, premium listings, and dealer services. The target audience includes private consumers and professional dealers seeking vehicles in Bulgaria and other European countries. The company benefits from brand recognition and a consistent, localized user experience. Growth opportunities exist in expanding services and enhancing security transparency.

Security posture

The website exhibits a solid security posture with mandatory HTTPS, use of reCaptcha Enterprise for bot protection, and a consent management platform ensuring GDPR compliance. Integration of anti-fraud scripts indicates proactive risk management. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is high but could be improved by publishing explicit security documentation and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and frameworks.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information for security issues.
  4. Regularly review and audit third-party scripts to mitigate supply chain risks.
  5. Enhance HTTP security headers visibility and report on SSL/TLS configuration.

Technical notes

Notes

The website uses a modern technology stack including React for frontend rendering, service workers for offline capabilities, and modular JavaScript. It integrates multiple analytics and advertising tools, including Google Tag Manager, Bing Ads, and Facebook Pixel, enabling comprehensive user tracking and marketing. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with potential for optimization in script loading and resource management. No CMS was explicitly detected, suggesting a custom or proprietary platform. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring.
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.
