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

Musée départemental Henri Matisse is a regional public museum located in Le Cateau-Cambrésis, France, dedicated to the works and legacy of Henri Matisse. It operates under the Département du Nord and offers exhibitions, events, educational workshops, and resources for both the general public and professionals. The museum holds recognized certifications such as Musée de France and Qualité Tourisme, reinforcing its cultural significance and trustworthiness. The website serves as an information portal and ticketing gateway, targeting art enthusiasts, families, and professionals in the cultural sector. Technically, the website employs a modern tech stack including jQuery, Bootstrap 4, FontAwesome, and Matomo analytics, hosted behind Cloudflare for DNS and security. The site is mobile optimized with good accessibility and basic SEO practices. However, some improvements are needed in explicit security headers and cookie consent mechanisms to enhance privacy compliance. From a security perspective, the site enforces HTTPS and uses secure external libraries, but lacks explicit security policies, incident response contacts, and a vulnerability disclosure mechanism. The absence of a cookie consent banner may pose GDPR compliance risks. Overall, the security posture is moderate with room for improvement in privacy and transparency. The domain registration is consistent and legitimate, with a domain age appropriate for the museum's online presence. The website is free from suspicious content or blocking mechanisms, providing a safe and professional user experience. Strategic recommendations include implementing cookie consent, enhancing security headers, publishing security policies, and adding vulnerability disclosure information to strengthen trust and compliance.

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

9 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

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 holds a strong regional position as a government-operated cultural institution with a clear focus on art and education. Its business model relies on public funding and partnerships with local tourism and cultural organizations. The website supports multiple revenue streams including ticket sales via a dedicated partner domain. The target audience spans general visitors, families, and professionals, with offerings tailored to each segment. The museum's partnerships with regional tourism and cultural bodies enhance its ecosystem and outreach. Growth indicators include active event scheduling and social media engagement. The museum maintains a consistent brand and professional content, supporting its credibility and market presence.

Security posture

The website demonstrates a moderate security maturity level with enforced HTTPS and use of secure libraries. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No security.txt or vulnerability disclosure page is present, limiting transparency for security researchers. The absence of a cookie consent mechanism indicates a compliance gap with GDPR requirements. Incident response readiness is not publicly documented. Overall, the security culture appears basic but functional, with opportunities to enhance privacy compliance and security transparency.

Recommendations

  1. Implement a GDPR-compliant cookie consent banner to inform users and obtain consent for tracking.
  2. Add explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit third-party libraries and scripts to ensure no vulnerable versions are in use.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries and frameworks such as jQuery, Bootstrap 4, Moment.js, and Anime.js, providing a responsive and interactive user experience. Hosting is managed via Cloudflare, offering DNS and security benefits. Performance is moderate with asynchronous loading of scripts and deferred JavaScript execution. Accessibility features include font size adjustments and dyslexia-friendly options. SEO is basic with meta tags present but no advanced structured data like JSON-LD detected. The site lacks a detectable CMS, suggesting a custom or static site architecture. Technical risks include missing security headers and absence of cookie consent, which could affect compliance and security posture.
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.
