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

De Nieuwe Schatkamer is a public-facing exhibition platform operated by De Nederlandsche Bank, the central bank of the Netherlands. The website offers visitors educational content about the economy, money collections, and art, supported by multimedia such as videos and games. It targets a broad audience including students, visitors, and the general public interested in finance and culture. The business model is government-driven, focusing on education and cultural engagement rather than commercial activities. The site is well-branded and consistent with the official bank identity. Technically, the website uses modern web technologies including Alpine.js and Google Tag Manager for analytics and marketing. The site is mobile-optimized, accessible, and SEO-friendly with proper metadata and structured navigation. Performance is moderate with good user experience and clear content presentation. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. However, it lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is good with clear cookie and privacy notices. Overall, the website presents a low-risk profile with strong legitimacy and trust indicators. Strategic improvements include adding security headers, publishing a security policy, and providing direct contact information for privacy and security inquiries.

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

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 26 days

      What to do: Renew SSL certificate before expiration

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 represents a government institution's initiative to educate and engage the public on financial and cultural topics related to the national bank. It holds a strong market position as an official source of information and cultural heritage. The business model is non-commercial, focusing on public education and cultural preservation. Key services include exhibitions, audiotours, educational games, and events. The target audience is broad, including students, educators, and visitors. The organization maintains an active social media presence and uses analytics to optimize user engagement. Growth indicators include a rich event agenda and multimedia content. Partnerships are implied with cultural and educational entities but not explicitly listed on the site.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent mechanisms in place. No critical vulnerabilities or exposed sensitive data were found. However, the absence of security headers and a published security policy or incident response contact reduces the overall security maturity. There is no evidence of a vulnerability disclosure program or security.txt file. The site complies with GDPR in terms of cookie usage and privacy notices but could improve transparency and incident readiness. Overall, the security posture is good but can be enhanced by adopting additional best practices and formal policies.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and provide dedicated contact channels for security incidents and vulnerability disclosures.
  3. Create and maintain a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Provide explicit contact information for the Data Protection Officer or privacy inquiries to enhance GDPR compliance.
  5. Regularly audit third-party scripts and tracking tools to ensure minimal privacy impact and maintain transparency.

Technical notes

Notes

The website uses a modern front-end stack with Alpine.js for interactivity and Google Tag Manager for analytics and marketing. The HTML is well-structured with semantic elements and accessibility features such as ARIA labels and keyboard navigation support. The site is mobile responsive and optimized for performance with lazy loading of images and videos. SEO is supported by proper meta tags, canonical links, and hreflang attributes for language targeting. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. The site could benefit from enhanced security headers and more explicit technical documentation.
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.
