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

Éditions D-BookeR is a small independent French publishing house specializing in IT and open-source related books, offering both digital and printed formats. The website is professionally designed using PrestaShop CMS, featuring a well-structured e-librairie with thematic content and a clear focus on educational materials for French-speaking IT professionals and enthusiasts. The technical infrastructure includes modern JavaScript libraries, Google Analytics, and reCAPTCHA for security on forms. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers and explicit policies could be improved. WHOIS data is missing, which slightly impacts trust but the website content and contact information support legitimacy. Overall, the site is well-positioned in its niche with good user experience and compliance with GDPR.

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

12 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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"

    • 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';…

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 company targets a niche market of French-speaking developers, educators, and open-source advocates, leveraging a direct-to-consumer e-commerce model for selling specialized IT books. The business model is focused on quality content authored by experts, with a strong emphasis on open-source and free software topics. The presence of social media channels and newsletter subscriptions indicates active engagement with its community. The lack of WHOIS data is a minor concern but does not detract significantly from the business credibility given the professional presentation and clear contact details.

Security posture

The website employs HTTPS with a valid SSL configuration and uses Google reCAPTCHA v2 to protect registration forms. A cookie consent banner is implemented to comply with GDPR. However, no advanced security headers were detected, and there is no visible security policy or incident response information. No vulnerabilities or exposed sensitive data were found in the content. The security posture is good but could be enhanced by adding security headers and explicit incident response contacts.

Recommendations

  1. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to enhance transparency and preparedness.
  3. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  4. Consider verifying and publishing WHOIS data or using a registrar that provides transparent domain registration information to improve trust.
  5. Enhance accessibility features to improve usability for all users, including those with disabilities.

Technical notes

Notes

The website is built on PrestaShop CMS, utilizing jQuery, Slick Carousel, and Google services such as Analytics and reCAPTCHA. The site is mobile-optimized with responsive design and good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with asynchronous loading of scripts and use of CDNs for libraries. The technical stack is modern and appropriate for an e-commerce publishing site. Opportunities exist to improve accessibility and implement additional security headers.
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.
