Gemeente Heemskerk is the official municipal government website for the town of Heemskerk in the Netherlands, providing a wide range of digital services and information for residents and businesses. The site offers key services such as passport and ID card applications, waste management, tax information, and local governance details. It maintains a strong local government presence with clear navigation and comprehensive content tailored to its community. Technically, the website is built on TYPO3 CMS, hosted by Cobytes, and uses Matomo for analytics, reflecting a modern and privacy-conscious infrastructure. The site is mobile-optimized, accessible, and SEO-friendly, with consistent branding and trust indicators including official social media channels. Security posture is solid with HTTPS, security headers, and no visible vulnerabilities, though it lacks some explicit security and privacy policy pages. Overall, the website demonstrates a mature digital presence suitable for a government entity, with room for improvement in privacy consent mechanisms and incident response transparency.

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

The website positions Gemeente Heemskerk as a key local government authority serving residents and businesses with essential municipal services. Its business model is public sector service provision, focusing on community engagement and digital accessibility. The site integrates with partner domains for sustainability, service platforms, and council meeting streaming, indicating a collaborative ecosystem. The presence of a dedicated careers site suggests organizational growth and recruitment efforts. The target audience is primarily local citizens and enterprises, with content in Dutch and some English support. The site reflects a medium-sized municipal operation with consistent branding and professional content, supporting trust and credibility in the local market.

Security posture

The security posture of the website is strong, with enforced HTTPS, appropriate security headers, and no detected exposed sensitive data or vulnerable libraries. The use of Matomo analytics aligns with privacy-conscious tracking. However, the absence of a dedicated security policy, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in transparency and readiness. No WAF or blocking mechanisms were detected, and the site is fully accessible. The site would benefit from publishing explicit security and incident response documentation and implementing a cookie consent mechanism to enhance compliance and user trust.

Recommendations

  1. Implement a visible cookie consent banner to comply with privacy regulations and improve user transparency.
  2. Publish a dedicated security policy and provide clear incident response contact information to enhance trust and preparedness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Include explicit data protection officer contact details to comply with GDPR requirements.
  5. Consider creating a terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust open-source content management system widely used by government entities. It uses modern web technologies including asynchronous JavaScript loading and responsive design techniques for mobile optimization. Hosting is provided by Cobytes, a known hosting provider. The site uses Matomo for analytics, favoring privacy over third-party trackers. Performance is moderate with multiple CSS assets compressed and merged. Accessibility features such as skip navigation and ARIA labels are implemented, supporting inclusive design. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. No critical technical debt or vulnerabilities were identified, though the site could improve by consolidating CSS assets to enhance load times.
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.
