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

The website paris.fr is the official digital portal for the City of Paris, providing comprehensive information and services to residents, visitors, and businesses. It serves as a central hub for municipal services, citizen participation, cultural events, and practical information about the city. The site is well-positioned as an authoritative source for local governance and community engagement in Paris. Technically, the website employs modern web technologies including Font Awesome for icons, Matomo for privacy-conscious analytics, and Algolia for search functionality. The use of StimulusJS and Turbolinks suggests a modern, responsive, and interactive user experience. The site is well-optimized for mobile devices and accessibility, with good SEO practices and performance. From a security perspective, the site enforces HTTPS, implements strong security headers, and avoids exposing sensitive data. However, explicit security policies and incident response information are not publicly available, and no vulnerability disclosure program or security.txt file was found. Privacy compliance is strong, with clear privacy and cookie policies and consent mechanisms in place. Overall, the site demonstrates a high level of professionalism, trustworthiness, and compliance with relevant regulations. The lack of WHOIS data is consistent with AFNIC policies for .fr domains and does not detract from the site's legitimacy. Strategic recommendations include enhancing transparency around security policies and vulnerability reporting 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

5 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: Facebook, LinkedIn, YouTube, Cloudflare

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

  2. 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

Paris.fr operates as a government entity website, focusing on delivering public services and information to a broad audience including residents, tourists, and businesses. Its competitive advantage lies in its official status and comprehensive coverage of city services and events. The business model is non-commercial, centered on public service and civic engagement. Revenue streams are not applicable. The site supports growth in digital citizen participation and transparency. Partnerships with related city platforms like agir.paris.fr and decider.paris.fr enhance its ecosystem. The site reflects a mature digital presence aligned with municipal objectives.

Security posture

The website exhibits a mature security posture with enforced HTTPS, robust security headers, and no visible vulnerabilities or exposed sensitive data. The use of integrity attributes on external scripts and privacy-focused analytics (Matomo) further enhance security and privacy. However, the absence of a published security policy, incident response plan, and vulnerability disclosure program represents gaps in transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies. The site would benefit from formalizing and publishing security governance documents and establishing clear channels for security incident reporting.

Recommendations

  1. Publish a dedicated security policy and incident response information page to increase transparency.
  2. Implement and publicize a vulnerability disclosure program, including a security.txt file.
  3. Enhance data retention policy disclosures related to analytics and user data.
  4. Regularly audit third-party scripts and dependencies for security vulnerabilities.
  5. Promote security awareness and trust by highlighting certifications or compliance achievements.

Technical notes

Notes

The technical infrastructure is modern and well-implemented, leveraging contemporary JavaScript frameworks and libraries to deliver a responsive and accessible user experience. The use of Algolia for search and Matomo for analytics indicates a focus on performance and privacy. The site appears to be hosted on government infrastructure with no reliance on commercial cloud providers evident. Performance is moderate with room for optimization. Accessibility and SEO are well addressed. Technical risks are minimal but continuous monitoring of third-party components is recommended to mitigate supply chain risks.
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.
