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

The Métropole du Grand Nancy website serves as the official digital presence for the metropolitan government of the Grand Nancy region in France. It provides comprehensive information about metropolitan governance, urban planning, public transportation, cultural events, and citizen services. The site targets residents, visitors, and local businesses, offering a broad range of public sector services and information. The website is well-positioned as a trusted government resource with a consistent brand and professional content. Technically, the site is built on TYPO3 CMS with modern front-end frameworks including Bootstrap and Vue.js, ensuring a responsive and user-friendly experience. It integrates analytics via Matomo and manages cookie consent effectively with the Tarteaucitron tool. The site demonstrates good mobile optimization and SEO practices, although some accessibility improvements could be made. From a security perspective, the website enforces HTTPS and employs cookie consent mechanisms, but lacks some advanced security headers and a published security policy or vulnerability disclosure program. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data is privacy-protected, which is typical for government-related domains, and no suspicious patterns were found. Overall, the website presents a low-risk profile with strong business credibility and good technical implementation. Strategic recommendations include enhancing security headers, publishing a security policy, and improving accessibility compliance to further strengthen trust and 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

3 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 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. GDPR outside view

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

    • 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

  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

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 Métropole du Grand Nancy operates as a public sector entity focused on metropolitan governance and public services. Its market position is that of an essential government authority serving a large regional population. The business model is non-commercial, centered on providing information and services to citizens and stakeholders. Key competitive advantages include official status, comprehensive service offerings, and integration with local digital services and applications. The website supports growth and engagement through event promotion, citizen participation, and digital service access. Partnerships with local service providers and integration with social media enhance its ecosystem. The site reflects a mature digital presence aligned with public sector standards.

Security posture

The website exhibits a mature security posture with mandatory HTTPS enforcement and cookie consent management aligned with GDPR requirements. Security headers are partially implemented, and no sensitive data leakage or vulnerable libraries were detected. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and incident readiness. The use of third-party scripts such as Facebook Pixel and Matomo is managed with user consent, reducing privacy risks. Overall, the site maintains a secure environment appropriate for a government portal but should enhance security communication and controls.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and user trust.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance website accessibility to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly audit and update third-party scripts and libraries to minimize security risks and maintain compliance.

Technical notes

Notes

The website leverages TYPO3 CMS, a robust open-source content management system, combined with Bootstrap for responsive design and Vue.js for interactive components. The integration of Matomo analytics and Tarteaucitron for cookie management reflects a commitment to privacy and data protection. The site loads multiple CSS and JS assets from both its own domain and trusted CDNs, indicating a distributed but controlled infrastructure. Performance is moderate, with opportunities to optimize asset loading and caching. The site is mobile-optimized and SEO-friendly, with proper meta tags and structured navigation. Technical debt appears low, but ongoing maintenance of dependencies and security updates is recommended to sustain operational stability.
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.
