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 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. 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 Twente operates as an essential healthcare entity providing public health services in the Twente region. Its business model is non-commercial, focusing on public service delivery. The organization leverages digital channels to disseminate health information and facilitate contact with the public. The website's integration with social media platforms and use of structured data enhance its outreach and credibility. While no direct revenue streams are evident, the organization's value lies in public health impact and community engagement. The absence of commercial advertising and affiliate programs aligns with its public service nature. The partnership ecosystem includes digital service providers like Matomo and Google Translate but no commercial partners are identified. Growth indicators include regular news updates and active social media presence. Strategic observations suggest opportunities to enhance security transparency and incident response readiness.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. Use of CSRF tokens in forms indicates attention to secure input handling. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security represents an area for improvement. No incident response or security policy pages are published, limiting transparency on security governance. The use of Matomo analytics reflects a privacy-conscious approach, avoiding common privacy pitfalls of third-party trackers. No vulnerabilities or malware indicators were detected. Compliance with GDPR is supported by clear privacy and cookie policies, though cookie consent mechanisms are missing. Overall, the security maturity is good but could be enhanced by adopting additional security headers and publishing formal security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to strengthen defense-in-depth.
  2. Publish explicit security and incident response policies to improve transparency and preparedness.
  3. Introduce a cookie consent mechanism to fully comply with EU cookie regulations and enhance user privacy control.
  4. Consider adding a vulnerability disclosure or security.txt page to facilitate responsible reporting of security issues.
  5. Regularly review and update third-party scripts and libraries to mitigate risks from vulnerable components.

Notes

The website is built on Joomla CMS with Bootstrap 5.3.1 and jQuery 3.7.1, indicating a modern and maintainable technology stack. Use of Matomo analytics and GTranslate enhances functionality while respecting privacy and accessibility.

Mobile optimization and accessibility features are well implemented, contributing to good SEO and usability. The site uses structured data (JSON-LD) for improved search engine understanding.

No technical debt or deprecated technologies were detected. Overall, the technical infrastructure supports the organization's digital goals effectively.
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.
