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

Cdiscount is a major French e-commerce platform offering a wide range of products including furniture, electronics, home improvement, garden, and sports goods. The website targets French consumers looking for affordable prices and convenient online shopping experiences. It provides services such as secure payment options, installment plans, free delivery over certain amounts, and a loyalty program. The platform also offers mobile plans and travel booking services, indicating a diversified e-commerce ecosystem. Technically, the website employs modern web technologies including React and jQuery, with a responsive design optimized for mobile and desktop users. The presence of JSON-LD structured data and comprehensive meta tags supports good SEO practices. Performance is moderate with extensive use of JavaScript and external resources. Accessibility features and SEO optimizations are well implemented. From a security perspective, the site enforces HTTPS with strong SSL configuration and includes security headers such as Content Security Policy and X-Frame-Options. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, explicit security policies and incident response contacts are not prominently published, which could be improved to enhance transparency and trust. Overall, the website is professional, trustworthy, and compliant with GDPR, featuring clear privacy and cookie policies with consent mechanisms. The lack of WHOIS data reduces domain registration transparency but does not significantly impact the site's legitimacy given its established market presence. Strategic recommendations include publishing detailed security policies, incident response contacts, and vulnerability disclosure information to further strengthen security posture and user trust.

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: Facebook, YouTube

      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 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

Cdiscount holds a strong position in the French e-commerce market, leveraging competitive pricing and a broad product catalog to attract a wide consumer base. Its business model combines direct sales and marketplace offerings, supported by financing options and loyalty programs to increase customer retention. The company maintains partnerships for services such as product repairs and certifications, enhancing its ecosystem. The website's integration with multiple social media platforms and marketing tools indicates a mature digital marketing strategy. Growth indicators include diversified service offerings and continuous promotional campaigns. The absence of explicit company registration details on the site suggests reliance on brand recognition and established market presence rather than transparency of corporate data on the homepage.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, modern security headers, and no visible exposure of sensitive information in the HTML content. The use of Content Security Policy and other headers mitigates common web vulnerabilities. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness for security incidents. GDPR compliance is evident through detailed privacy and cookie policies with consent mechanisms. The extensive use of third-party tracking and advertising scripts introduces potential privacy risks, though these are managed with consent banners. Overall, the security maturity is good but could be enhanced by formalizing incident response and vulnerability disclosure processes.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and user protections.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Review and minimize third-party tracking scripts to reduce privacy risks and improve user trust.
  5. Enhance transparency by including company registration and legal information prominently on the website.

Technical notes

Notes

The website uses a modern tech stack centered on React and jQuery, with extensive use of asynchronous JavaScript and CSS for responsive and interactive user experience. Structured data in JSON-LD format supports SEO and rich search results. The site is mobile-optimized with adaptive layouts and touch-friendly controls. Performance is moderate due to the volume of scripts and external resources, but caching and CDN usage help mitigate latency. Accessibility features such as skip links and ARIA attributes are present, improving usability for assistive technologies. Technical risks include reliance on multiple third-party scripts which may introduce vulnerabilities or performance bottlenecks. Opportunities exist to streamline scripts and enhance security headers further.
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.
