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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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 museum operates as a non-profit cultural entity targeting art enthusiasts and the general public interested in cultural heritage. Its business model revolves around exhibitions, educational outreach, and partnerships with other cultural institutions. The website supports this model by providing ticketing links, e-shop access, and newsletter subscriptions. The museum's market position is strong regionally, supported by a domain age of over a decade and active social media engagement. The partnership with external ticketing and cultural sites indicates a collaborative ecosystem. Revenue streams likely include ticket sales, merchandise, and event hosting. Growth indicators include active event programming and international exhibition participation.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent mechanisms that respect user privacy preferences. The use of a WordPress plugin to prevent user enumeration is a positive security control. However, no explicit security headers (e.g., CSP, HSTS) were detected in the HTML content, which could enhance protection against common web attacks. No exposed sensitive data or vulnerable libraries were identified. Incident response and security policy documentation are not publicly available, which is common for cultural institutions but could be improved for transparency. Overall, the site is secure for its purpose but could benefit from additional hardening measures.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection.
  2. Publish a clear security policy and incident response plan accessible to users and partners.
  3. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider adding a terms of service page to clarify user rights and responsibilities.

Technical notes

Notes

The website is built on WordPress 6.5.2 with a custom theme 'iq-theme' and uses React for some frontend components. It leverages Google Tag Manager for analytics and marketing, and jQuery for legacy support. The site loads multiple JavaScript bundles asynchronously, indicating a modular approach. Fonts are preloaded for performance optimization. The site is mobile responsive with adaptive images for different devices. SEO is enhanced via Yoast SEO plugin with structured data (JSON-LD) for rich snippets. Hosting appears to be managed by Gransy, consistent with the registrar information. Performance is moderate with room for improvement in caching and script optimization. Accessibility is basic with skip links and ARIA labels but could be further enhanced.
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.
