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

Security score

80/100

Risk levelLow

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

Librairie Quae operates as a specialized online bookstore focused on scientific literature, offering a broad catalog of printed and digital books, including open access ebooks through its partner platform Quae-open. The website demonstrates a professional e-commerce infrastructure with modern technologies such as jQuery, Google Analytics, Matomo, and Owl Carousel, and is built likely on a Ruby on Rails framework. The site is well-structured with clear navigation and a responsive design, targeting scientists, professionals, and the general public interested in science. However, the absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. Security posture is adequate with HTTPS and CSRF protections, but lacks advanced security headers and explicit policies such as privacy and terms of service. Cookie consent is implemented, indicating some privacy compliance efforts. Overall, the site is functional and trustworthy in content but requires improvements in transparency and security documentation.

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 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. 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

The business positions itself as a niche scientific book retailer with a focus on education and open access content. Its business model revolves around e-commerce sales of printed and digital scientific books, supplemented by multimedia content like blogs, videos, and podcasts to engage its audience. The partnership with Quae-open enhances its market offering by providing free open access ebooks. The company targets a medium-sized market segment primarily in France, catering to both professionals and the general public interested in scientific knowledge. The lack of explicit company registration and contact details on the website suggests a need for improved business transparency to strengthen customer trust.

Security posture

The website employs HTTPS and includes CSRF tokens in forms, indicating baseline security practices. It uses multiple analytics and tracking services, which may raise privacy concerns if not properly disclosed. The absence of security headers such as Content-Security-Policy and lack of a published security policy or incident response contacts indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The missing WHOIS data is a notable risk factor for domain legitimacy. Overall, the security posture is moderate but could be enhanced by implementing comprehensive security headers, publishing privacy and security policies, and establishing clear incident response mechanisms.

Recommendations

  1. Verify and update WHOIS domain registration information to ensure transparency and legitimacy.
  2. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  4. Add a security.txt file and clearly state incident response contacts to improve vulnerability disclosure and response readiness.
  5. Review and disclose data collection and retention policies related to analytics and tracking to improve privacy compliance.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Bootstrap components, Owl Carousel for product display, and multiple analytics platforms (Google Analytics and Matomo). The presence of CSRF tokens and cookie consent mechanisms indicates attention to security and privacy basics. The site is mobile responsive with good navigation clarity and SEO optimization. However, the absence of explicit hosting provider information and security headers suggests potential technical debt. Performance is moderate, with room for optimization in loading speed and accessibility features. The Ruby on Rails framework inferred from form tokens suggests a robust backend platform. Overall, the technical infrastructure supports a professional e-commerce experience but could benefit from enhanced security and privacy technical controls.
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.
