Low risk. 2 critical or high findings in GDPR outside view and SSL/TLS.

Security score

78/100

Risk levelLow

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

Manufacture Mercier is a heritage French brand specializing in premium cycling apparel, leveraging a century-old legacy dating back to 1919. The company operates an e-commerce platform built on Shopify, targeting discerning cyclists seeking high-quality textiles designed in France and manufactured in Europe. The website reflects a strong brand identity with rich multimedia content and a professional design that enhances user experience and trust. Technically, the site employs modern web technologies and integrates multiple marketing and analytics tools, ensuring robust performance and customer engagement. Security posture is solid with HTTPS enforcement and privacy compliance, although explicit security policies and incident response details are absent. The domain WHOIS data is unavailable, which introduces some uncertainty regarding domain registration legitimacy, but the overall digital presence and branding suggest a credible business. Strategic recommendations include publishing security policies, improving transparency on incident response, and addressing WHOIS data gaps to enhance 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

2 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.

    • 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

  2. 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 business positions itself as a niche player in the premium cycling apparel market, leveraging its historical brand heritage as a competitive advantage. Its business model focuses on direct-to-consumer e-commerce sales, supported by digital marketing via Klaviyo and social media channels. The company targets cycling enthusiasts who value quality and tradition. The website's content and navigation are optimized for conversions, with clear product categories and storytelling elements that reinforce brand loyalty. The absence of direct contact emails or phone numbers suggests a preference for controlled customer interactions via forms. The partnership with Shopify and use of third-party services like Boxtal and Revy indicate a mature digital ecosystem supporting logistics and checkout processes.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, secure payment integrations, and cookie consent mechanisms aligned with GDPR. However, the lack of published security policies, incident response contacts, and vulnerability disclosure channels limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of multiple third-party scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the site is secure for e-commerce operations but could improve trust by publishing formal security documentation and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy and incident response page including contact channels.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Ensure WHOIS data is complete and consistent with business claims to improve domain trust.
  4. Regularly audit third-party scripts and dependencies for security vulnerabilities.
  5. Enhance visible trust signals such as security certifications or badges on the website.

Notes

The website is built on the Shopify platform, utilizing Liquid templates and a modern JavaScript stack including jQuery and lazy loading libraries for performance optimization. It integrates video content hosted on Vimeo and marketing tools such as Klaviyo and Facebook Pixel for customer engagement and analytics. The site is mobile-optimized with responsive design and accessibility considerations. Hosting is via Shopify's CDN ensuring fast global delivery. The technical implementation is robust with good SEO and accessibility practices. Opportunities exist to further optimize security headers and streamline third-party script usage to reduce potential attack surface.
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.
