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

Citeo is a French eco-organization specializing in the Extended Producer Responsibility (REP) for household packaging and graphic papers. It plays a key role in promoting recycling and environmental sustainability for producers and businesses in France. The website is professionally designed, primarily in French, and targets businesses involved in packaging and paper production. Technically, the site uses modern frameworks such as Nuxt.js and integrates multiple analytics and tracking tools with a clear cookie consent mechanism, reflecting a mature digital infrastructure. Security posture is good with HTTPS and security headers in place, though explicit security policies and incident response contacts are not published. The absence of WHOIS data for the domain reduces trustworthiness slightly, but the overall professional presentation and compliance with privacy regulations indicate a legitimate and established organization.

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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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

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

Citeo holds a leading position in the French environmental sector, focusing on recycling and producer responsibility. Its business model revolves around facilitating compliance with environmental regulations for packaging and paper producers. The company targets a B2B audience, including manufacturers and distributors. The website content and structure suggest a large organization with a clear branding strategy and consistent messaging. The use of advanced analytics and marketing tools indicates a focus on data-driven decision-making and user engagement. However, the lack of visible direct contact details and WHOIS transparency may be areas for improvement in business credibility and customer trust.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement and multiple security headers. Cookie consent is managed via a recognized tool (Tarteaucitron), and analytics scripts are loaded with privacy considerations. No obvious vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response information, and vulnerability disclosure mechanisms limits transparency and preparedness perception. The domain's missing WHOIS data is a concern for domain ownership verification and trust. Overall, the security posture is good but could be enhanced by publishing formal policies and contact channels for security incidents.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Provide clear incident response contact information, including abuse and security emails.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Regularly review and audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website is built on a modern JavaScript framework (Nuxt.js) with server-side rendering capabilities, improving SEO and performance. It uses several third-party analytics and marketing tools such as Piano Analytics, Hotjar, Google Tag Manager, and social media tags. The site is mobile-optimized with responsive design and includes accessibility considerations, though these could be improved. Performance is moderate, with many preloaded scripts and assets. No CMS was explicitly detected, suggesting a custom or framework-based solution. Hosting provider details are not evident from the HTML content. Overall, the technical infrastructure is robust and supports the business needs effectively.
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.
