Risk levelMedium

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

Boutique CentraleSupélec is an official e-commerce merchandise store serving the CentraleSupélec community, including students, alumni, faculty, and partners. The website offers branded textiles, accessories, and goodies to reinforce the institution's identity and community belonging. The site is built on the Shopify platform, leveraging standard Shopify technologies and integrations, hosted on Google Cloud infrastructure. It features a cookie consent mechanism and privacy policy compliant with GDPR, presented in French. However, no explicit contact information or terms of service pages are found, which could be improved for transparency and trust. The domain WHOIS data shows an anomalous future creation date, which may be a data error but warrants attention. Security posture is generally good with HTTPS and domain transfer protections, but lacks DNSSEC and security headers. Overall, the site is professional, accessible, and trustworthy for its niche audience.

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. 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 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
    • 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 operates in the education and e-commerce sectors, focusing on official merchandise for a prestigious engineering school. Its market position is niche but authoritative, leveraging the CentraleSupélec brand. The business model is direct retail via an online store, targeting community members who value institutional identity. Partnerships include form services and an internal boutique site. The site shows consistent branding and good content quality, supporting a positive user experience. Growth potential lies in expanding product offerings and enhancing customer engagement through improved contact and policy transparency.

Security posture

The website employs HTTPS with valid SSL and domain status protections, indicating a baseline secure setup. However, the absence of DNSSEC and security headers like Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No incident response or security policy information is published, limiting transparency in case of security events. The cookie consent mechanism and privacy policy indicate GDPR awareness, but no vulnerability disclosure or security.txt is present. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is moderate but could be strengthened with additional controls and disclosures.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Publish clear contact information including support emails and phone numbers to enhance trust and customer service.
  4. Add terms of service and security policy pages to improve legal transparency and compliance.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.

Technical notes

Notes

The website is built on Shopify, a mature e-commerce platform, using modern web technologies including JavaScript, CSS, and HTML5. It uses Google Fonts and is hosted on Google Cloud infrastructure, ensuring reliable performance and scalability. The site is mobile-optimized and includes accessibility features such as skip links and ARIA roles. SEO is supported by proper meta tags and structured data (JSON-LD). Performance is moderate, with deferred and async loading of scripts. Technical debt appears low, but improvements could be made in security headers and DNS configuration. Overall, the technical implementation is solid and appropriate for the business needs.
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.
