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

De Friesland is a large Dutch healthcare insurance provider offering a range of health insurance products including basic, supplementary, dental, and collective insurances. The website targets consumers, employers, and healthcare providers, providing services such as premium calculation, claims processing, and customer support. The company is part of the Achmea group, a major player in the Dutch insurance market. The website content is well structured, professionally designed, and provides clear navigation and relevant information for its audience. Technically, the website uses a modern CMS (Sitecore) and integrates advanced search capabilities via Coveo, along with Vue.js and jQuery for frontend interactivity. Hosting appears to be on Microsoft Azure infrastructure. However, performance metrics are not available, and the SSL/TLS configuration is currently inadequate, lacking a valid certificate and modern protocol support, which is a significant security concern. Security posture is mixed; while security headers and CSP are well implemented, the absence of a valid SSL certificate and disabled TLS protocols severely undermine the site's security. Privacy compliance is strong with clear privacy and cookie policies and GDPR adherence. The site uses extensive analytics and marketing tools, indicating a mature digital marketing strategy but also raising user tracking concerns. Overall, the site is professional and credible but must urgently address SSL/TLS issues to ensure secure user interactions and maintain trust. Strategic recommendations include obtaining a valid SSL certificate, enabling modern TLS protocols, and enhancing security configurations to protect user data and comply with best practices.

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.

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

De Friesland holds a strong position in the Dutch healthcare insurance market, serving over 600,000 customers with a broad portfolio of insurance products. Its affiliation with Achmea enhances its market credibility and operational scale. The business model focuses on providing comprehensive health insurance solutions tailored to various customer segments including individuals, employers, and healthcare providers. The company leverages digital channels effectively for customer engagement, claims processing, and service delivery. Partnerships with related insurance entities like Zilveren Kruis and Interpolis indicate a collaborative ecosystem. Growth indicators include active content marketing, customer satisfaction scores, and digital service offerings such as mobile apps and online claims. The company’s strategic focus on customer-centric services, digital transformation, and regional healthcare collaboration positions it well for sustained market relevance. However, technical and security improvements are necessary to support this growth and maintain competitive advantage.

Security posture

The current security maturity level of the website is moderate but compromised by critical SSL/TLS deficiencies. The site employs robust Content Security Policy headers, XSS protection, and other security headers that mitigate common web vulnerabilities. Cookies are set with Secure and HttpOnly flags, enhancing session security. The presence of a responsible disclosure page reflects a proactive security culture. However, the lack of a valid SSL certificate and disabled TLS protocols expose users to risks such as data interception and man-in-the-middle attacks. The absence of OCSP stapling and session resumption further weakens the security posture and performance. There is no explicit incident response or security policy information available on the site, which could be improved to enhance transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies, but the extensive use of tracking and marketing tools requires careful management to avoid privacy risks. Overall, the site needs urgent remediation of its SSL/TLS configuration to align with industry standards and protect user data effectively.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to secure all user connections.
  2. Enable TLS 1.2 and TLS 1.3 protocols and disable outdated protocols to enhance encryption strength.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Publish a clear security policy and incident response plan accessible to users and stakeholders.
  5. Review and optimize third-party tracking tools to balance marketing needs with user privacy.
  6. Regularly audit and update security headers and CSP to maintain protection against emerging threats.
  7. Enhance contact information visibility with verified company emails and phone numbers for better trust.

Notes

The website is built on the Sitecore CMS platform, leveraging modern frontend technologies such as Vue.js and jQuery. It integrates Coveo for advanced search capabilities and uses Microsoft Azure for hosting and monitoring. The site is mobile optimized with responsive images and accessible navigation. However, performance data is missing, and the SSL/TLS configuration is critically lacking, with no valid certificate and no enabled TLS protocols. This technical gap poses a risk to secure communications and user trust. The extensive use of third-party analytics and marketing tools indicates a mature digital marketing infrastructure but also introduces complexity and potential privacy concerns. The site structure and meta tags are well implemented, supporting SEO and accessibility. Overall, the technical infrastructure is solid but requires urgent security upgrades and performance monitoring to ensure reliability and safety.
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.
