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

The website www.visiterlyon.com serves as the official tourism portal for Lyon and its metropolitan area, operated by the Office du Tourisme et des Congrès de la métropole de Lyon. It provides comprehensive tourism information, online booking services for hotels, restaurants, leisure activities, and city passes such as the Lyon City Card. The site targets tourists, families, business travelers, and groups, positioning itself as an authoritative and trusted source for visiting Lyon. The content is rich, professionally presented, and available in multiple languages, enhancing accessibility and user experience. Technically, the website employs modern web technologies including Alpine.js for interactivity, Swiper.js for sliders, and MapLibre GL for mapping. It integrates Google Tag Manager and Google reCAPTCHA for analytics and security. The site is mobile-optimized, accessible, and SEO-friendly, with good performance metrics. Security best practices are observed with HTTPS enforcement, security headers, and secure forms, although explicit security policy and incident response information are not published. The security posture is strong with no detected vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with clear privacy and cookie policies, GDPR adherence, and consent mechanisms. However, WHOIS data for the domain is missing or unavailable, which is unusual for an official entity and slightly impacts trustworthiness. Despite this, the website's certifications, social media presence, and comprehensive content support its legitimacy. Overall, the website is a high-quality, secure, and user-friendly platform for promoting tourism in Lyon. Strategic recommendations include publishing a dedicated security policy, incident response contacts, and a vulnerability disclosure policy to further enhance trust 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

4 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 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn

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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 Office du Tourisme et des Congrès de la métropole de Lyon operates www.visiterlyon.com as a central hub for tourism promotion in Lyon. The business model revolves around providing tourism information and facilitating online sales of city passes, guided tours, and leisure activities. The site serves a broad audience including leisure tourists, families, business travelers, and groups. It leverages partnerships with related domains for professional tourism, press, and events. The presence of multiple certifications and quality labels underscores its commitment to service excellence. The website's multilingual support and comprehensive content indicate a mature digital strategy aimed at maximizing visitor engagement and satisfaction.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented. Use of Google reCAPTCHA on forms mitigates automated abuse. No sensitive data is exposed in the HTML content. However, the absence of a publicly available security policy and incident response contact information represents a compliance gap. No vulnerability disclosure or security.txt file is found, limiting transparency for security researchers. Overall, the site is secure but could improve by publishing explicit security governance documents and contact channels for incident reporting.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update WHOIS information to ensure transparency and trust.
  5. Enhance privacy compliance by detailing data retention policies and user rights more explicitly.

Technical notes

Notes

The website uses a modern and performant technology stack including Alpine.js for reactive UI components, Swiper.js for interactive sliders, and MapLibre GL for map rendering. Google Tag Manager and reCAPTCHA are integrated for analytics and security. The site is mobile responsive with good accessibility features and SEO optimization. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is moderate, likely due to rich media content and external dependencies. Hosting provider details are not available from the data. Overall, the technical infrastructure supports a robust and user-friendly experience with opportunities for further optimization.
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.
