Risk levelLow

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

Coöperatie Menzis is a well-established Dutch healthcare cooperative focused on transforming care towards health and vitality. The organization operates as a cooperative with members rather than shareholders, providing health insurance and collaborating with healthcare providers and municipalities to ensure accessible and affordable care. The website reflects a mature digital presence with professional design, clear navigation, and relevant content tailored to a broad audience including insured members and healthcare partners. Technically, the site uses modern analytics tools such as Microsoft Application Insights and Google Tag Manager, and is built on the Sitecore CMS platform. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though there is room for improvement in publishing explicit security policies and incident response contacts. Overall, the domain registration and WHOIS data align well with the business claims, indicating a trustworthy and legitimate online presence.

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

2 findings rated critical or high. Fix these first.

  1. 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

  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

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 cooperative business model positions Coöperatie Menzis uniquely in the Dutch healthcare market, emphasizing member participation and social responsibility. Their market position is strong given their long history and integration with the broader Menzis brand. Key services include health insurance, preventive health initiatives, and regional healthcare collaboration. The organization targets a wide audience from individual insured persons to healthcare providers and municipalities. The website supports this with comprehensive content and links to corporate governance and sustainability information, indicating transparency and accountability. Partnerships with domains like menzis.nl reinforce their ecosystem. Growth indicators include ongoing digital transformation and regional healthcare projects.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enabled and cookie consent implemented, reflecting GDPR compliance. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests areas for enhancement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of reputable analytics tools is balanced with privacy considerations. Security headers were not explicitly detected in the provided data, which could be improved to harden the site against common web attacks. Overall, the security maturity is adequate for the business type but could benefit from formalized policies and transparency.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance transparency around data retention policies related to analytics and cookies.

Technical notes

Notes

The website is built on the Sitecore CMS platform, leveraging JavaScript and modern analytics tools including Microsoft Application Insights and Google Tag Manager. The site is mobile optimized with good accessibility and SEO practices. Performance is moderate, with potential for improvement through optimization of resources and caching. The technical stack is modern and supports scalability and maintainability. No deprecated or vulnerable libraries were detected. The use of asynchronous script loading and consent-based cookie management reflects good technical maturity. Opportunities exist to improve security headers and formalize technical documentation for security and privacy.
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.
