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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Business profile

GGD Fryslân holds a strong position as the official public health authority for the Fryslân region, providing essential health services including disease prevention, vaccination, and health promotion. The organization operates under a public service model funded by government sources, targeting residents and healthcare partners. The website reflects a consistent brand and professional content aligned with its mission. Partnerships with related domains such as fryslanveilig.nl and ggdberoepsvaccinaties.nl indicate a collaborative ecosystem in regional health services. The use of advanced analytics and consent tools suggests a focus on data-driven insights and regulatory compliance. No commercial or affiliate programs are evident, consistent with its public sector nature.

Security posture

The website enforces HTTPS and uses a comprehensive cookie consent mechanism via Cookiebot, allowing granular user control over cookie categories. Analytics tools like Piwik PRO and Hotjar are used with privacy considerations. No security headers were explicitly detected in the HTML, suggesting room for improvement in HTTP header security. No exposed sensitive data or vulnerable libraries were found in the source. The absence of published security policies or incident response contacts limits transparency in security governance. Overall, the security posture is good but could be enhanced by publishing formal security policies, incident response procedures, and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish terms of service to clarify user rights and obligations.
  4. Enhance HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly review and audit third-party scripts and cookies to ensure ongoing privacy compliance.

Technical notes

Notes

The website is built on the Umbraco CMS platform, leveraging modern JavaScript modules and integrates multiple third-party services including Cookiebot for consent management, Piwik PRO and Google Tag Manager for analytics, and Monsido for accessibility and analytics. The site is mobile optimized and accessible, with good SEO meta tags and Open Graph data. Performance is moderate, likely influenced by multiple external scripts. The technical stack is modern and well-maintained, but hosting provider details are not explicitly identified. There is an opportunity to improve security headers and formalize security documentation to reduce technical risks.
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.
