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

Truck1 Sp.z.o.o. operates Alle-Lkw.de, a well-established online marketplace specializing in used trucks and commercial vehicles in Germany. Founded in 2003, the platform offers a comprehensive catalog of over 350,000 listings including trucks, trailers, motorhomes, and other commercial vehicles. The business targets both individual buyers and dealers, providing services such as vehicle listings, dealer registration, advertising, and leasing options. The website is part of a broader Truck1 brand ecosystem with multiple regional domains, indicating a strong market presence in Europe and beyond. Technically, the website employs a modern infrastructure with extensive use of third-party analytics and marketing tools including Google Tag Manager, Facebook Pixel, TikTok Analytics, and Criteo for retargeting. The site is hosted on Google Cloud DNS with HTTPS enforced, ensuring secure communications. The design is responsive and optimized for mobile devices, with good SEO practices and structured data enhancing search visibility. From a security perspective, the site demonstrates good practices such as HTTPS usage and security headers, but lacks publicly available privacy and cookie policies, security policies, and vulnerability disclosure information. The extensive use of third-party scripts increases the attack surface and requires ongoing monitoring. No critical vulnerabilities or WAF blocking were detected, indicating a stable security posture. Overall, Alle-Lkw.de is a credible and professional platform with a solid business model and technical foundation. To enhance trust and compliance, it is recommended to publish comprehensive privacy and cookie policies, implement a security policy page, and consider a vulnerability disclosure program. These steps will improve privacy compliance and security transparency, supporting long-term business growth and user confidence.

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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Truck1 Sp.z.o.o. holds a strong position in the European used commercial vehicle market, leveraging a multi-regional brand strategy with localized websites. The business model is based on an online marketplace connecting buyers and sellers, generating revenue through listing fees, advertising, and value-added services like leasing. The platform targets commercial vehicle dealers and end-users, offering a wide range of vehicle categories and popular dealers to enhance marketplace liquidity. The company benefits from a broad partnership ecosystem and a well-recognized brand, supporting growth and market penetration. The presence of multiple language and country-specific domains indicates strategic expansion and localization efforts.

Security posture

The website maintains a good security baseline with HTTPS enforced and several security headers present. The use of asynchronous loading for scripts and consent management for analytics reflects awareness of privacy and performance considerations. However, the absence of explicit privacy and cookie policies, security policies, and incident response contacts represents compliance gaps, especially under GDPR and NIS2 frameworks. The extensive third-party tracking and advertising scripts pose potential privacy risks and require vigilant management. No critical vulnerabilities or exposed sensitive data were identified, but the site would benefit from formalizing security documentation and vulnerability disclosure mechanisms to enhance security culture and incident readiness.

Recommendations

  1. Publish comprehensive privacy and cookie policies accessible from the homepage footer.
  2. Implement a dedicated security policy and incident response page with clear contact channels.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Audit and minimize third-party tracking scripts to reduce privacy risks and improve performance.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website utilizes a modern technology stack with Google Tag Manager, multiple Google Analytics properties, Facebook Pixel, TikTok Analytics, Criteo, LinkedIn Insight Tag, Bing Ads UET, Twitter tracking, and Taboola for advertising and analytics. Hosting is managed via Google Cloud DNS with Google-managed nameservers, ensuring reliable infrastructure. The site uses responsive design with CSS and JavaScript optimized for mobile and desktop. Performance is moderate with asynchronous script loading and preloading of critical CSS. SEO is supported by meta tags, Open Graph, Twitter cards, and JSON-LD structured data. Technical risks include reliance on numerous third-party scripts which may introduce vulnerabilities or privacy concerns if not regularly audited.
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.
