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

The Groupe Caisse des Dépôts is a major French public financial institution dedicated to serving the public interest through investment, social policies, and sustainable development initiatives. The website reflects a mature digital presence with comprehensive content, clear navigation, and multilingual support, targeting French citizens, investors, and public sector entities. The business model focuses on public investment and service provision, positioning the group as a key player in France's financial and governmental sectors. Technically, the site is built on Drupal 10 with modern frontend frameworks such as Bootstrap and various JavaScript libraries enhancing user experience. Hosting is supported by Imperva CDN, ensuring content delivery efficiency. Accessibility and SEO practices are well implemented, though performance metrics are unavailable. Privacy compliance is robust, with clear GDPR-aligned policies and cookie consent mechanisms. Security posture shows strengths in HTTP security headers and policy configurations; however, the absence of a valid SSL/TLS certificate and HTTPS enforcement is a critical vulnerability that significantly impacts the site's security rating. No WAF or blocking mechanisms were detected, allowing full content accessibility. Contact mechanisms are well established, including a dedicated Data Protection Officer email. Overall, the site demonstrates high professionalism and trustworthiness but requires urgent remediation of SSL/TLS issues to ensure secure communications and maintain user trust.

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

6 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

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 Groupe Caisse des Dépôts operates as an essential public financial institution in France, focusing on investment management, social policy support, and public services. Its market position is strong, supported by a large organizational size and extensive service offerings including retirement information, mécénat, and digital trust services. The website's integration with partner domains and government services indicates a broad partnership ecosystem. The business model emphasizes public interest and sustainable development, targeting a diverse audience from citizens to investors and public entities. The digital presence is mature, reflecting strategic investments in content quality and user engagement.

Security posture

The website exhibits a moderate security maturity level with well-configured HTTP security headers such as HSTS, X-Content-Type-Options, and X-XSS-Protection. However, the lack of a valid SSL/TLS certificate and disabled HTTPS protocols represent a critical security gap, exposing users to potential interception and undermining trust. No explicit incident response or vulnerability disclosure policies were found, indicating potential gaps in security governance. The presence of a Data Protection Officer contact suggests some compliance with data protection regulations. Overall, the security posture requires immediate improvement in SSL/TLS deployment and enhanced transparency in security policies.

Recommendations

  1. Install and enforce a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or higher) and configure OCSP stapling and session resumption for improved security and performance.
  3. Publish a clear security policy and vulnerability disclosure program to enhance transparency and incident response readiness.
  4. Review and restrict the Access-Control-Allow-Origin header to trusted domains to reduce cross-origin risks.
  5. Maintain and regularly update privacy and cookie policies to ensure ongoing GDPR compliance and user trust.
Technical notes

Notes

The website is built on a robust Drupal 10 CMS platform, leveraging Bootstrap for responsive design and multiple JavaScript libraries (jQuery, Popper.js, GSAP, ScrollMagic) for enhanced interactivity. Hosting is via Imperva CDN, providing content delivery optimization. Accessibility and SEO are well addressed, with multilingual support and structured navigation. However, performance data is missing, limiting assessment of load times and resource efficiency. The absence of SSL/TLS is a significant technical risk. The site uses modern cookie consent tools (Didomi) and analytics (Dynatrace, Matomo), indicating a mature digital infrastructure with attention to privacy and user tracking.
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.
