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

GroeiGids.nl is a well-established Dutch platform providing reliable information and support for parents and expecting parents, focusing on child development, health, and parenting from pregnancy through puberty. The website offers a comprehensive app, a chat service with youth nurses, and regional health service locators, positioning itself as a trusted resource in the healthcare and non-profit sectors in the Netherlands. The domain has been active since 2004, indicating a mature presence in its market segment. Technically, the site is built on a modern Angular framework with Angular Material components, ensuring a responsive and user-friendly experience. It uses Matomo Analytics for privacy-conscious user tracking and implements DNSSEC for domain security. The site is mobile-optimized and has good SEO practices, although accessibility features could be improved. From a security perspective, the site enforces HTTPS and includes a cookie consent mechanism, but lacks explicit security headers and published security policies or incident response information. No vulnerabilities or exposed sensitive data were detected. The WHOIS data confirms the domain's legitimacy and consistency with the website's purpose. Overall, the website demonstrates a strong business credibility and technical foundation with moderate security maturity. Strategic improvements in security headers, incident response transparency, and accessibility would enhance its posture and trustworthiness further.

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

5 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

GroeiGids operates as an important entity in the healthcare and non-profit sectors, targeting parents and caregivers in the Netherlands. Its business model centers on providing free, reliable information and digital tools (app and chat) to support child health and development. The platform leverages its long-standing domain and trusted brand to maintain a strong market position. Growth indicators include over 200,000 app users and integration with regional youth health services. The absence of direct commercial elements suggests a focus on public health and community support rather than revenue generation. Partnerships with regional health organizations are implied but not explicitly detailed in the content.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and DNSSEC enabled, which are strong foundational controls. The presence of a cookie consent dialog aligns with GDPR compliance. However, the absence of key security headers (e.g., Content-Security-Policy, X-Frame-Options) and lack of published security or incident response policies represent gaps. No vulnerability disclosures or security.txt files were found, limiting transparency for security researchers. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate for an informational site but could be improved to meet higher standards and regulatory expectations.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response information to improve transparency and preparedness.
  3. Introduce a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to comply with WCAG standards and improve user experience for all visitors.
  5. Regularly audit third-party libraries and dependencies to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built as a Single Page Application using Angular 18 and Angular Material, indicating a modern and maintainable front-end architecture. It uses Matomo Analytics, a privacy-focused analytics platform, avoiding reliance on major third-party trackers. The site is mobile-optimized with responsive design and good SEO metadata. Hosting details are not explicit, but DNSSEC and HTTPS indicate a secure domain and transport layer. Performance is moderate, likely due to SPA nature and external script loading. There is room for improvement in accessibility and security headers. Overall, the technical infrastructure supports a professional and user-friendly experience with opportunities for further hardening and optimization.
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.
