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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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 website targets the Dutch occupational health market, focusing on vaccination services for employees and employers. Its business model is service-oriented, backed by public health institutions. The presence of partner domains related to travel and tailored vaccinations indicates a broader ecosystem collaboration. The site’s content and branding are consistent and professional, supporting high trustworthiness. However, the absence of direct contact details and security policies suggests areas for improvement in transparency and user engagement. The integration of modern web technologies and compliance tools reflects a commitment to digital maturity and regulatory adherence.

Security posture

The site exhibits a solid security foundation with enforced HTTPS, modern security headers, and secure form handling via Drupal. Cookie consent is managed effectively through Cookiebot, ensuring GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap and potential risk in incident management readiness. Enhancing these areas would strengthen the overall security culture and user trust.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  3. Include explicit contact information for data protection officer or security team.
  4. Regularly review and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance user engagement by providing clear contact channels and terms of service.

Technical notes

Notes

The website is built on Drupal 10, a modern and secure CMS platform, with integration of Google Tag Manager and Cookiebot for analytics and consent management. Performance is moderate with good mobile optimization and accessibility features such as ReadSpeaker for text-to-speech. SEO is supported by proper meta tags and canonical links. The site uses asynchronous loading for scripts to improve load times. No major technical debt or outdated technologies were observed. Opportunities exist to improve hosting transparency and implement advanced security headers or CSP policies for enhanced protection.
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.
