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

Michelin is a globally recognized leader in the manufacturing of composites and mobility experiences, with a history spanning over 130 years. The company focuses on innovation in material science and sustainable mobility solutions, targeting a broad audience including consumers, investors, and media. The website reflects a mature digital presence with comprehensive content, professional design, and consistent branding. Technically, the site leverages modern frameworks such as Astro and Svelte, integrates advanced analytics and consent management tools, and is hosted on reliable cloud infrastructure. Security posture is strong with HTTPS and GDPR compliance, though there is room for improvement in security headers and incident response transparency. The absence of WHOIS data is a notable anomaly but does not detract significantly from the overall trustworthiness given the corporate nature and quality of the site.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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: Facebook, Twitter, LinkedIn, YouTube

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

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

Michelin operates in the transportation and manufacturing sectors, offering products and services related to composites, tires, polymer solutions, and connected mobility. The company maintains a strong market position as a pioneer in material science and sustainable mobility. Its business model is centered on innovation, quality, and sustainability, appealing to a wide range of stakeholders including individual consumers, institutional investors, and industry partners. The website supports this positioning with detailed governance, investor relations, and product information. The use of multiple analytics and marketing tools indicates a sophisticated approach to customer engagement and data-driven decision making.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS and a GDPR-compliant cookie consent mechanism managed by Didomi. Integration of analytics tools like Piano Analytics, Mouseflow, and Kameleoon is done with user consent. However, the site lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms, which are best practices for corporate websites. Security headers are not explicitly detected in the provided data, suggesting potential improvements. No vulnerabilities or exposed sensitive data were identified. Overall, the security posture is good but could be enhanced by publishing security policies and adding security.txt files.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page including contact information for reporting security issues.
  3. Add a vulnerability disclosure program or security.txt file to encourage responsible reporting of security vulnerabilities.
  4. Enhance accessibility features to improve compliance with standards and user experience for all visitors.
  5. Provide clear terms of service and contact information to improve transparency and business credibility.

Technical notes

Notes

The website is built using modern web technologies including the Astro framework and Svelte components, indicating a forward-looking technical infrastructure. Content is served via Azure Blob Storage, ensuring scalability and reliability. The site integrates multiple third-party analytics and marketing tools with consent management, reflecting a mature approach to data privacy and user tracking. Performance is moderate with room for optimization, particularly in accessibility and SEO. The CMS identified is ApostropheCMS, a robust platform for content management. Overall, the technical stack supports a high-quality user experience but could benefit from enhanced security configurations and performance tuning.
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.
