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

The Musée Matisse de Nice is a government-affiliated cultural institution dedicated to the life and works of Henri Matisse. The website serves as the official digital presence, providing comprehensive information about exhibitions, collections, visitor information, and educational activities. It targets art enthusiasts, tourists, families, and researchers, positioning itself as a key cultural museum within the Ville de Nice museum network. The business model is primarily non-profit and government-supported, focusing on cultural preservation and public engagement. Technically, the website is built on WordPress with modern frameworks such as Bootstrap and jQuery, integrating Matomo for analytics and Complianz for GDPR-compliant cookie management. The site demonstrates good mobile optimization, accessibility, and SEO practices, with a moderate performance profile. The use of trusted third-party services for ticketing and online shop enhances user experience. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms, but lacks explicit security headers and a public security policy or vulnerability disclosure page. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain trust assessment, but the presence of official certifications and government logos supports legitimacy. Overall, the website is professional, secure, and compliant with privacy regulations, offering a trustworthy platform for visitors and stakeholders. Strategic improvements in security headers and incident response transparency could further enhance its security posture.

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

5 findings rated critical or high. Fix these first.

  1. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. 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

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 market position as a recognized cultural institution in Nice, supported by the local government. Its competitive advantage lies in its unique collection dedicated to Henri Matisse and its integration within the network of 11 museums in Nice. Revenue streams likely include ticket sales, online shop purchases, and public funding. The target customer segments include local and international tourists, art scholars, and families seeking educational activities. Growth indicators include active exhibition programming and digital engagement via newsletters and social media. Partnerships with ticketing platforms and cultural organizations strengthen its ecosystem. The website reflects a mature digital presence aligned with its cultural mission.

Security posture

The current security maturity level is moderate to good. HTTPS is enforced site-wide, and cookie consent is managed in compliance with GDPR. The use of Matomo analytics respects user privacy with consent requirements. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a gap. No public incident response or vulnerability disclosure information is available, which could hinder rapid mitigation of security issues. Data protection practices appear sound with no exposed sensitive data. Overall, the security culture is adequate but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party plugins and scripts to ensure no vulnerable libraries are in use.
  5. Enhance WHOIS domain registration transparency by ensuring accurate and accessible registrant information.

Technical notes

Notes

The website leverages a well-established CMS (WordPress) with a modern tech stack including Bootstrap and jQuery for responsive design and interactivity. Performance is moderate, with room for optimization in image loading and script management. Accessibility features such as skip links and ARIA labels are present, supporting inclusive user experience. SEO is supported by proper meta tags, Open Graph, and structured data in JSON-LD format. The integration of GDPR-compliant cookie management and analytics tools reflects a mature approach to privacy and data governance. Technical risks are minimal but include potential plugin vulnerabilities and missing security headers.
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.
