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

Mulhouse.fr is the official municipal website of the city of Mulhouse, France, providing comprehensive information and services to residents and visitors. The site covers a wide range of topics including employment, municipal administration, urban development projects, culture, education, health, and social services. It serves as a central hub for local government communication and citizen engagement, featuring news, interactive maps, and access to various public resources. Technically, the website is built on WordPress CMS with a modern tech stack including Bootstrap for responsive design, jQuery, Swiper.js for interactive elements, and Matomo Analytics configured with privacy by design principles. The site demonstrates good mobile optimization, accessibility, and SEO practices, supported by Yoast SEO plugin and structured data in JSON-LD format. From a security perspective, the site enforces HTTPS and uses a cookie consent management tool (tarteaucitron) to comply with privacy regulations. However, no explicit security headers were detected, and there is no visible security policy or incident response information published. The WHOIS data is unavailable, likely due to registry restrictions or privacy protection, which limits domain registration trust verification but does not detract from the site's legitimacy given its official nature. Overall, Mulhouse.fr presents a professional, trustworthy, and user-friendly platform for municipal services and information. Strategic recommendations include enhancing security headers, publishing a security policy, and adding vulnerability disclosure mechanisms to further strengthen security posture and transparency.

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

8 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

  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 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

Mulhouse.fr operates as a government essential entity serving the public sector in France. Its market position is that of an official city government portal, providing critical services and information to the local population and visitors. The business model is non-commercial, focused on public service delivery and community engagement. Key competitive advantages include comprehensive content coverage, integration with partner cultural and social sites, and a privacy-conscious analytics approach. The site supports multiple user segments including residents, businesses, tourists, and civic participants. Growth indicators include active content updates, digital service expansion (mobile app), and ongoing urban development project communications. The partnership ecosystem includes local cultural institutions, tourism offices, and health organizations, enhancing the city’s digital presence and service reach.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and privacy-respecting analytics via Matomo. The use of tarteaucitron for cookie consent aligns with GDPR compliance. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security represents a gap that could expose the site to certain web-based attacks. No exposed sensitive data or vulnerable libraries were detected, indicating good maintenance practices. The lack of a published security policy or incident response contact limits transparency and preparedness communication. No vulnerability disclosure or security.txt file was found, which could hinder coordinated vulnerability reporting. Overall, the site is secure for general public use but would benefit from enhanced security controls and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party libraries and plugins to mitigate potential vulnerabilities.
  5. Enhance user trust by providing transparency on data retention policies and security practices.

Technical notes

Notes

The website is built on a WordPress platform using a modern and widely supported technology stack including Bootstrap for responsive design and jQuery for interactivity.

Performance is moderate with room for optimization, especially in image loading and script management. Accessibility features are present and the site is mobile optimized.

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.
