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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

GGD Zuid-Limburg operates as a government healthcare entity serving the Zuid-Limburg region. Its market position is that of a key public health authority providing essential health services and preventive care. The organization collaborates with municipalities, schools, and healthcare partners to promote health equity and safety. The business model is publicly funded healthcare service delivery with a focus on community health outcomes. The website reflects a medium-sized organization with a clear mission and target audience including residents, professionals, and partners. The presence of social media channels and a career section indicates active engagement and growth orientation. No parent or subsidiary companies were identified, consistent with a regional government entity.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure form submissions. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is publicly available, which could hinder rapid response to security incidents. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are lacking, representing a compliance gap. No exposed sensitive data or vulnerable libraries were detected. Overall, the security maturity is good but could be improved by adding security headers, incident response transparency, and cookie consent.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Add a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Introduce a cookie consent mechanism to comply fully with GDPR and enhance user trust.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Regularly review and update third-party scripts and analytics tools to minimize potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust open-source content management system widely used in government and enterprise sectors. The use of compressed CSS and JavaScript assets indicates optimization efforts. Google Tag Manager is used for analytics and marketing tracking. The site is mobile responsive with good accessibility features such as skip links and ARIA labels. Performance is moderate, suggesting potential for further optimization. No outdated or vulnerable libraries were detected in the HTML content. The technical infrastructure supports a professional and functional user experience aligned with the organization's mission.
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.
