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

Gesondheetszentrum is a healthcare center based in Luxembourg specializing in preventive medicine, health screening, and wellness services for both individuals and corporate clients. The website presents a professional and accessible platform offering detailed information about their services including medical check-ups, psycho health, coaching, and a specialized burn-out management program called PROTEA. The center targets a broad audience concerned with proactive health management. Technically, the website is built on WordPress, uses modern JavaScript libraries like jQuery, and integrates Google Tag Manager and Juicer.io for analytics and social media feeds. The site is mobile-optimized and includes accessibility features, enhancing user experience. Security-wise, the site uses HTTPS and avoids exposing sensitive data, but lacks explicit security headers and published security policies. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the website is trustworthy and professional but would benefit from improved privacy and security disclosures.

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

9 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

  2. Security headers

    • High

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

Gesondheetszentrum operates in the healthcare sector focusing on preventive medicine and wellness in Luxembourg. Their business model includes providing comprehensive health check-ups and mental health services to individuals and companies, positioning themselves as a specialized health partner. The website references partnerships with local health organizations and foundations, indicating a collaborative ecosystem. The content and structure suggest a small-sized organization with a clear focus on quality and client engagement. The absence of detailed company registration or VAT information is noted but not uncommon for small healthcare providers. The site’s integration with social media and educational platforms supports their outreach and credibility.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible sensitive data leaks. However, it lacks important security headers such as Content Security Policy, HSTS, and X-Frame-Options, which could improve protection against common web attacks. There is no published incident response or vulnerability disclosure policy, which limits transparency and preparedness. The use of Google Tag Manager introduces some tracking but is standard practice. No vulnerable libraries or outdated scripts were detected in the provided content. The site should enhance its security documentation and implement recommended HTTP headers to strengthen its security stance.

Recommendations

  1. Publish and link a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Add an incident response and vulnerability disclosure policy page with contact channels for security issues.
  4. Consider appointing and publishing Data Protection Officer contact information if applicable under GDPR.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built on WordPress and uses jQuery along with Google Tag Manager and Juicer.io for social media integration. The site is mobile responsive and includes accessibility features such as an accessibility panel and ARIA labels. Performance appears moderate with asynchronous loading of analytics scripts. The site uses EuroDNS nameservers indicating a reputable hosting provider. SEO is supported by proper meta tags, Open Graph tags, and JSON-LD structured data describing the organization and webpage. There is no evidence of technical debt or deprecated technologies in the provided content. Opportunities exist to improve security headers and privacy compliance to modern standards.
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.
