Security score

70/100

Risk levelMedium

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

Auchan Retail is a large, established French retail company focused on food commerce, local products, franchising, and energy partnerships. The website presents a professional and consistent brand image with a clear mission to improve quality of life through healthy and sustainable food. The digital infrastructure uses modern technologies including Bootstrap and a CMS named Snowboard, delivering a good user experience with mobile optimization and structured navigation. Security posture is solid with HTTPS and secure form handling, though some security headers are missing and no cookie consent mechanism is detected. The absence of WHOIS data for the domain is unusual and slightly reduces trust, but the website content and social media presence strongly support legitimacy. Overall, the site is well-built and credible but could improve privacy compliance and security header implementation.

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. 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

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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 Retail operates in the retail sector with a strong focus on food and local sourcing, supported by franchising and energy partnerships. The company is part of the Association Familiale Mulliez group, indicating a large enterprise with a broad market presence. The website targets consumers, partners, and collaborators, emphasizing sustainability and community engagement. Key revenue streams likely include retail sales, franchise fees, and energy projects. The company maintains active communication through a newsroom and social media channels, supporting brand trust and market positioning. The lack of WHOIS transparency is a minor concern but does not detract significantly from the business credibility.

Security posture

The website enforces HTTPS and uses secure forms with CSRF tokens, indicating good baseline security practices. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected in the provided data, which are recommended to mitigate common web attacks. There is no visible incident response or vulnerability disclosure information, which could be improved to enhance security culture and transparency. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is good but could be strengthened by adding security headers and formalizing incident response contacts.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web vulnerabilities.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish a security policy and incident response contact information to improve trust and readiness for security events.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.

Technical notes

Notes

The website uses a modern tech stack with Bootstrap CSS and JavaScript, supported by the Snowboard CMS platform. The site is mobile optimized and has good SEO practices with proper meta tags and Open Graph data. Performance is moderate, with video content and image assets used for rich media presentation. The site lacks visible security headers which is a technical gap. Hosting provider details are not available from the data. Overall, the technical implementation is solid with room for security and privacy enhancements.
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.
