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. 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

  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

Heisterkamp operates in the transportation sector, offering integrated solutions that cover transport, rental, sales, and maintenance. Their business model focuses on providing end-to-end services to logistics companies and freight operators. The company leverages its long history and large asset base to maintain a competitive advantage. The website indicates a focus on sustainability with green solutions and climate neutrality initiatives. Their marketing ecosystem includes active social media presence and digital advertising via Google and LinkedIn. The company appears to be targeting medium to large enterprises requiring comprehensive transport solutions. The multilingual website supports international business development. No parent or subsidiary companies are explicitly mentioned, suggesting an independent operation. The company’s digital maturity is high, with a well-structured site and integrated analytics and marketing tools.

Security posture

The website demonstrates a good security posture with HTTPS enabled and use of reCAPTCHA v3 to protect forms from abuse. Cookie consent mechanisms are implemented, supporting GDPR compliance. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not clearly present or documented, representing an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response contact reduces transparency and may impact trust for security-conscious users. The WHOIS privacy protection is standard and justified. Overall, the security maturity is solid but could be enhanced by publishing formal policies and improving header configurations.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  5. Enhance transparency around data retention policies and GDPR compliance details.

No major technical debt or deprecated technologies were detected. Hosting provider details are not explicitly available from the content.
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.
