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

7 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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';…

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

The company operates in the transportation sector with a focus on commercial vehicles and equipment. Founded in 2003, Truck1.dk has grown into a large platform with a broad European presence, supported by multiple country-specific domains and language versions. Its competitive advantage lies in its extensive inventory, dealer network, and integrated marketing and analytics infrastructure. Revenue streams likely include listing fees, advertising services, and leasing facilitation. The target customer segments include vehicle dealers, fleet operators, and individual buyers/sellers. The platform's partnership ecosystem includes related Truck1 domains and allied marketplaces like alle-lkw.de. Strategic observations suggest a strong market position with opportunities to enhance security transparency and incident response capabilities.

Security posture

The website demonstrates a good security posture with HTTPS enforced, presence of key security headers (HSTS, CSP, X-Frame-Options, etc.), and secure handling of user inputs in forms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly accessible security policy, incident response contact information, or vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. The extensive use of third-party scripts necessitates regular security audits to mitigate supply chain risks. Overall, the security maturity is solid but could be enhanced by formalizing security policies and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Regularly review and update third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website uses a modern JavaScript-heavy front-end with multiple asynchronous third-party scripts for analytics, advertising, and tracking. It leverages Google Tag Manager to manage tags efficiently. The site is mobile-optimized with responsive design and uses structured data (JSON-LD) for SEO enhancement. Performance is moderate, likely impacted by numerous external scripts. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML. The site employs good SEO practices with meta tags, Open Graph, and alternate hreflang links for internationalization. Technical risks include dependency on multiple third-party services which require continuous monitoring for vulnerabilities.
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.
