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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Vroon operates in the transportation sector with a diversified portfolio of shipping services, positioning itself as a key player in vessel management and offshore support. The business model focuses on providing specialized shipping solutions to a global market, leveraging a fleet of modern vessels. The company’s website content and structure indicate a focus on professionalism and client engagement, with clear calls to action for contact and service inquiries. The absence of direct contact emails or phone numbers suggests a preference for controlled communication channels via web forms. The use of third-party services like Cookiebot and Google Analytics indicates an awareness of data privacy and marketing effectiveness. No direct partnerships or subsidiaries were identified from the website content or linked domains.

Security posture

The website employs HTTPS with strong SSL configuration and security headers such as HSTS, X-Content-Type-Options, and Content-Security-Policy, indicating a mature security posture. Cookie consent is implemented with granular control over cookie categories, enhancing privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy or incident response contact information limits transparency and preparedness visibility. There is no evidence of vulnerability disclosure or security certifications. Overall, the security posture is solid but could benefit from enhanced policy disclosures and incident response readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Add a terms of service page to clarify user agreements and legal protections.
  5. Enhance website accessibility features to improve compliance and user experience.

Technical notes

Notes

The website uses a modern frontend stack including Vite for module bundling, htmx for dynamic content, and Cookiebot for cookie management. Google Tag Manager and Google Analytics are integrated for analytics and marketing. Video content is embedded via Vimeo with autoplay and muted settings. The site is mobile optimized with responsive images and accessible navigation. Performance is moderate with preloading of fonts and asynchronous script loading. No CMS or hosting provider details were explicitly detected. The technical implementation is robust with opportunities to improve accessibility and add more explicit metadata for SEO and compliance.
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.
