0–100, higher is better. How it is calculated

Museumvereniging operates the website museum.nl, serving as a comprehensive portal for museums across the Netherlands. The organization provides key services including museum information, event promotion, and management of the Netherlands Museum Pass. Positioned as a leading non-profit in the cultural sector, the website targets museum visitors, families, and tourists interested in Dutch cultural heritage. The site features a professional design with consistent branding and good content relevance. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager, and Google Analytics for tracking. It uses HTTPS with excellent SSL configuration, lazy loading images, and responsive design for mobile optimization. However, no explicit CMS or hosting provider details are evident. SEO practices are good with proper meta tags and structured data. From a security perspective, the site enforces HTTPS and uses anti-CSRF tokens but lacks visible security headers and published security policies. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is supported by clear privacy and cookie policies with consent mechanisms, though GDPR-specific details could be more explicit. Overall, the website is trustworthy and professionally maintained with moderate to good scores across content quality, technical implementation, security posture, privacy compliance, and business credibility. Strategic improvements in security headers and incident response disclosures would enhance the security posture further.

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

Museumvereniging holds a strong market position as the national museum association in the Netherlands, offering a centralized platform for museum-related information and services. Its business model is non-profit, focusing on cultural promotion and facilitating museum visits through the Museum Pass. The organization leverages partnerships with museums and cultural institutions, maintaining a focused target audience of museum visitors and families. The website supports growth through event promotion and digital engagement, with social media channels on Facebook and Instagram. Revenue streams likely include Museum Pass sales and membership fees. The platform demonstrates moderate digital maturity with room for technical modernization and enhanced security transparency.

Security posture

The website demonstrates a solid baseline security posture with HTTPS enforced and no visible exposure of sensitive data. Use of anti-CSRF tokens indicates awareness of common web security practices. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose the site to certain attacks. No incident response or vulnerability disclosure policies are published, limiting transparency and preparedness. Privacy policies and cookie consent mechanisms align with GDPR requirements but could be more detailed. Overall, the security maturity is moderate, with recommendations to enhance header implementation and publish security policies to improve trust and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance privacy policy details to explicitly address GDPR compliance and data retention practices.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website uses a modern front-end stack with JavaScript, SVG icons, and web fonts optimized for performance. Google Tag Manager and Google Analytics are integrated for marketing and analytics purposes. The site employs lazy loading for images and responsive design for mobile devices, contributing to good user experience. However, no explicit CMS or backend platform is identified, suggesting a custom or proprietary solution. Performance is moderate, with potential improvements in accessibility and SEO through enhanced ARIA attributes and structured data expansion. Hosting details are not disclosed, and security headers are missing, indicating areas for technical enhancement to strengthen security and compliance.
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.
