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

Museumvereniging operates the website museum.nl, a leading platform dedicated to promoting museums and cultural events in the Netherlands. The site provides comprehensive information about museums, exhibitions, events, and the Netherlands Museum Pass, targeting a broad audience of museum visitors and cultural enthusiasts. The organization positions itself as a key non-profit entity supporting Dutch museums and cultural heritage. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager, and Google Analytics for analytics and marketing purposes. The site is well-optimized for mobile devices, features lazy loading for images, and uses SVG icons for scalable graphics. SEO and accessibility practices are well implemented, contributing to a positive user experience. From a security perspective, the site enforces HTTPS and includes a cookie consent mechanism compliant with GDPR. However, it lacks explicit security policy documentation and incident response contact information. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns with the website's claims, showing consistent registrant information and domain age appropriate for the business. Overall, the website demonstrates a strong balance of content quality, technical implementation, and privacy compliance, with room for improvement in formal security policy disclosures and incident response readiness.

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.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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 primary source for museum-related information and services in the Netherlands. Its non-profit business model focuses on cultural promotion and facilitating museum visits through the Museum Pass. The organization benefits from a well-established brand and digital presence, including active social media channels. Revenue streams likely include Museum Pass sales and partnerships with museums. The platform serves a diverse audience ranging from local residents to international tourists interested in Dutch culture. Strategic partnerships with museums and cultural institutions enhance its ecosystem and outreach capabilities.

Security posture

The website exhibits a moderate to good security posture with HTTPS enforced and cookie consent implemented. However, the absence of a published security policy and incident response contacts indicates a gap in transparency and preparedness. No security headers were detected in the provided data, suggesting an opportunity to strengthen defenses against common web attacks. The use of Google Analytics and Tag Manager introduces moderate user tracking, which is managed with GDPR-compliant consent. Overall, the security maturity is adequate for the site's purpose but could be enhanced by formalizing security governance and improving header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance transparency around data retention policies related to analytics and user data.

Technical notes

Notes

The website is built using modern front-end technologies with asynchronous loading of scripts and lazy loading of images to optimize performance. Google Tag Manager and Google Analytics are integrated for marketing and analytics purposes. The site uses SVG icons and custom fonts loaded with font-display swap for better user experience. The HTML structure is semantic and includes meta tags for SEO and social sharing (Open Graph and Twitter cards). Mobile optimization and accessibility features such as contrast toggle and language selection are present. No CMS or hosting provider details were explicitly detected. Performance is moderate with room for improvement in caching and security header implementation.
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.
