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

9 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

      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

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

Business profile

PreventionBTP.fr occupies a strong position in the French construction safety market as an authoritative source backed by OPPBTP. Its business model focuses on providing free and paid prevention tools, training, and informational resources to construction companies and professionals. The site leverages partnerships with related domains and social media channels to extend reach and engagement. The organization benefits from ISO 9001 certification, reinforcing quality and trust. Growth indicators include active content updates, webinars, and a broad suite of online tools. The target customer segments are construction firms, safety coordinators, and trainers. The site’s ecosystem includes partner sites for project owners and safety coordinators, enhancing its comprehensive service offering.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of a consent management platform (Didomi), and integration of reputable analytics tools with privacy considerations. No exposed sensitive data or vulnerable libraries were found in the HTML content. However, explicit security headers such as Content-Security-Policy and X-Frame-Options were not confirmed and should be verified. The absence of a published security policy or incident response page is a gap in transparency. No vulnerability disclosure or security.txt files were detected. Overall, the site aligns well with GDPR compliance and best practices but could improve by publishing explicit security policies and incident response contacts.

Recommendations

  1. Verify and explicitly implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response page with contact information for security issues.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities.
  4. Enhance contact information visibility, including official company emails and phone numbers for support and inquiries.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and user expectations.

Technical notes

Notes

The website is built using modern front-end technologies, primarily React with Tailwind CSS for styling and Goober for CSS-in-JS animations. It leverages multiple analytics and tracking services including Matomo, Hotjar, and Google Tag Manager, integrated with a consent management platform (Didomi) to ensure GDPR compliance. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. Performance is moderate, likely due to multiple external scripts and rich media content. No CMS was explicitly detected, suggesting a custom or headless architecture. Hosting provider details are not available from the HTML content. Overall, the technical infrastructure supports a professional and user-friendly experience with room for performance optimization.
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.
