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.

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

PDOK holds a key position in the Dutch geo-data ecosystem, providing essential government data services free of charge. Its business model focuses on public service and open data dissemination, supported by Kadaster. The platform's integration with community forums and related geo-data catalogs enhances its ecosystem. The use of standardized OGC APIs and continuous platform improvements indicate a commitment to interoperability and innovation. The absence of direct contact emails or phone numbers suggests a focus on digital self-service and community support. PDOK's partnerships with Geoforum and Nationaal Geo Register strengthen its market presence and user engagement.

Security posture

The website employs HTTPS with strong SSL configuration and security headers including CSP with nonce, indicating a solid baseline security posture. Forms include CSRF tokens, and no sensitive data is exposed in the HTML. However, there is no publicly visible security policy or incident response contact information, which could be improved to enhance transparency and readiness. The use of third-party analytics (Piwik PRO) with IP tracking enabled is noted, but privacy policies are comprehensive and consent mechanisms are in place. No vulnerabilities or outdated libraries were detected in the provided content.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance HTTP security headers by adding HSTS and X-Frame-Options if not already configured.

Technical notes

Notes

The platform is built on Liferay CMS with extensive use of Alloy UI and React components, indicating a modern and scalable architecture. The site uses combined and minified JavaScript and CSS resources for performance optimization. Accessibility and SEO best practices are observed, including language attributes, ARIA labels, and canonical links. The presence of multiple viewers and API endpoints demonstrates a complex but well-integrated technical infrastructure. Hosting appears stable and likely government-managed, with no signs of performance bottlenecks or technical debt in the analyzed content.
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.
