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

1 finding rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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 agency's market position is strong as a government entity providing essential healthcare data services. Its business model is non-commercial, focused on public service and data transparency. The website links to multiple partner domains related to healthcare registries and data systems, indicating a broad partnership ecosystem. The content is professionally curated, targeting healthcare providers, policymakers, and researchers. Growth indicators include regular updates, conferences, and new data modules. The organization benefits from government backing, enhancing credibility and stability.

Security posture

The website enforces HTTPS and implements a robust cookie consent mechanism using Matomo analytics with explicit user consent. However, no HTTP security headers were detected in the provided data, which is a recommended improvement area. There is no visible security policy or incident response contact information, which could enhance transparency and readiness. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security posture is good but could be strengthened by adding security headers and formal security policies.

Recommendations

  1. Implement standard HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and provide incident response contact details to improve transparency and trust.
  3. Consider adding a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance WHOIS data transparency or clarify domain registration details to improve domain trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Foundation framework, Slick Carousel, and Magnific Popup for UI components. Matomo is used for analytics with a consent-based approach. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and structured navigation. Performance is moderate, with asynchronous loading of analytics scripts. No CMS was detected, suggesting a custom or government-managed platform. Hosting provider details are not available. The site demonstrates technical maturity suitable for a government healthcare portal but could benefit from enhanced security header implementation.
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.
