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

7 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

Auchan operates in the retail and e-commerce sectors with a business model focused on multi-channel shopping experiences. It maintains a strong market presence in France with extensive product offerings and promotional campaigns. The company leverages partnerships for services like catering, travel, ticketing, and photo services, enhancing its ecosystem. Revenue streams include online sales, in-store purchases, and loyalty programs. The target customer base is broad, encompassing everyday consumers seeking convenience and competitive pricing. The website's integration of marketing and tracking tools indicates a mature digital marketing strategy. Certifications such as 'Élu Service Client de l’Année 2025' reinforce customer trust. The absence of WHOIS data is a minor anomaly but does not detract significantly from the overall business credibility.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and integration of cookie consent tools ensuring GDPR compliance. Use of Google Tag Manager and other third-party scripts is managed with consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not confirmed, and no public security policy or incident response information is available. The lack of a vulnerability disclosure or security.txt file is a gap in transparency. Overall, the site follows good security practices but could improve by publishing security policies and enhancing header configurations.

Recommendations

  1. Verify and implement explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Consider adding a vulnerability disclosure program or security.txt file to improve transparency.
  4. Ensure continuous monitoring of third-party scripts for vulnerabilities.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

Auchan.fr uses a modern JavaScript-based front-end with RequireJS for module loading and Axios for HTTP requests. The site employs lazy loading for images and videos, improving performance and user experience. Google Tag Manager is used extensively for analytics and event tracking. The presence of OneTrust scripts indicates a robust cookie consent framework. The website is responsive and optimized for mobile devices with adaptive video sources. The CMS appears proprietary or custom-built, with no common CMS detected. Performance is moderate, with room for optimization in loading times and accessibility features. Overall, the technical infrastructure supports a scalable and user-friendly e-commerce platform.
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.
