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

Autotrader.pl is a prominent Polish online automotive marketplace operated by Domiporta Sp. z o.o., offering a wide range of vehicle listings including used and new cars, motorcycles, trucks, and automotive parts. It positions itself as the largest internet automotive exchange in Poland, targeting both consumers and businesses interested in vehicle transactions. The website features a professional design with good content relevance and clear navigation tailored to the Polish market. Technically, the site employs modern JavaScript libraries, Google Tag Manager, Facebook Pixel, and Cookiebot for consent management, indicating a mature digital infrastructure. Security-wise, the site enforces HTTPS and uses cookie consent mechanisms but lacks visible HTTP security headers and explicit privacy or security policies in the provided content. Overall, the site demonstrates a solid security posture with room for improvement in privacy compliance and contact transparency. The domain WHOIS data is not publicly available, which is typical for .pl domains managed by NASK, but the website's professional presentation and technology usage support its legitimacy.

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

3 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 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. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Autotrader.pl operates in the transportation sector as an essential business entity providing an online platform for automotive sales and parts distribution. Its business model revolves around connecting buyers and sellers through a comprehensive listing service. The company benefits from a strong market position as Poland's largest automotive marketplace, leveraging partnerships with major ad networks and tracking services to monetize traffic. The absence of explicit contact information and privacy policies suggests potential areas for enhancing customer trust and regulatory compliance. The website's integration with multiple third-party services indicates a broad partnership ecosystem, although no direct partner or subsidiary domains were identified. The platform's focus on the Polish market and medium company size aligns with its targeted audience and service offerings.

Security posture

The website maintains a good security baseline with HTTPS enforced and a cookie consent banner that complies with GDPR requirements to some extent. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense-in-depth posture. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of a security.txt file or incident response contact channels limits transparency in vulnerability disclosure and incident management. The use of multiple third-party tracking and advertising scripts increases the attack surface and necessitates regular security audits. Overall, the security posture is adequate but could be strengthened by implementing recommended HTTP headers, publishing security policies, and improving privacy documentation.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a clear and accessible privacy policy and terms of service pages to improve regulatory compliance and user trust.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve incident response readiness.
  4. Provide explicit company contact information including emails and phone numbers to enhance business credibility and customer support.
  5. Regularly audit and monitor third-party scripts and tracking technologies to mitigate potential security risks and ensure privacy compliance.

Technical notes

Notes

The website uses a modern technology stack including JavaScript, jQuery, Google Tag Manager, Facebook Pixel, and Cookiebot for consent management. It employs Modernizr for feature detection and FontFaceObserver for font loading optimization. Advertising is managed via Google Ad Manager and Adform, with retargeting through Criteo and Facebook Pixel. The site loads asynchronously and uses lazy loading for ads to optimize performance. Mobile optimization is basic, with a fixed minimum width and viewport settings that could be improved for responsiveness. Accessibility features are minimal but present. SEO is supported by proper meta tags and structured data, although no JSON-LD or Open Graph tags were explicitly found in the truncated HTML content. Hosting provider details are not evident from the HTML. Performance is moderate, with room for improvement in mobile responsiveness and accessibility.
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.
