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

The Commissariat à l'Énergie Atomique et aux Énergies Alternatives (CEA) is a major French public research organization focused on energy, defense, technology, and healthcare sectors. The website serves as a comprehensive portal for research, innovation, and public information, targeting government, industry, researchers, and citizens. It highlights CEA's role in advancing low-carbon energy, digital transformation, medical technologies, and national security. The site is well-structured, professionally designed, and rich in relevant content, reflecting the organization's authoritative position in its fields. Technically, the website is built on Microsoft SharePoint, leveraging modern web technologies including JavaScript, Matomo analytics, and Google reCAPTCHA for security and user interaction. The platform supports multimedia content and provides a responsive experience. While performance is moderate, the site maintains good SEO and accessibility standards. From a security perspective, the site uses HTTPS with good SSL configuration and standard SharePoint security features like form digest tokens. However, explicit security headers are not clearly visible, and no dedicated incident response or vulnerability disclosure mechanisms are published. Privacy compliance is addressed with a comprehensive privacy policy, though cookie consent mechanisms could be improved. Overall, the website presents a trustworthy and professional digital presence for a large, government-affiliated research entity. The absence of WHOIS data reduces transparency but is likely due to registry policies. Strategic recommendations include enhancing security headers, publishing incident response contacts, and implementing cookie consent for full GDPR compliance.

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

7 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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. 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

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

CEA holds a strong market position as a key public research institution in France, with a broad portfolio spanning energy, defense, healthcare, and digital technologies. Its business model revolves around research and innovation, supporting industrial competitiveness and national sovereignty. The organization engages with multiple stakeholders including government bodies, industrial partners, academic institutions, and the public. The website reflects a mature digital ecosystem with clear communication of services, research domains, and partnership opportunities. Growth indicators include active support for startups and technology transfer. The partnership ecosystem is extensive, involving specialized institutes and military applications divisions. The site’s content and structure support CEA’s strategic objectives and public mission effectively.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS encryption and use of Google reCAPTCHA to mitigate automated abuse. SharePoint’s built-in security mechanisms such as form digest tokens provide CSRF protection. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like X-Frame-Options and Content-Security-Policy is a gap that could be addressed to enhance protection against clickjacking and content injection attacks. The lack of a published incident response contact or security.txt file limits transparency and readiness for vulnerability reporting. Privacy policies are comprehensive, but cookie consent mechanisms are not clearly implemented, which may affect GDPR compliance. Overall, the security maturity is good but could benefit from formalizing vulnerability disclosure and enhancing HTTP security headers.

Recommendations

  1. Implement and verify HTTP security headers such as X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy to strengthen browser security.
  2. Publish an incident response contact or security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  3. Introduce a cookie consent banner or mechanism to comply fully with GDPR and enhance user privacy control.
  4. Regularly audit third-party scripts and analytics tools to ensure no vulnerable or deprecated libraries are in use.
  5. Enhance accessibility features and mobile optimization to improve user experience across all devices.

Technical notes

Notes

The website is built on Microsoft SharePoint, a robust enterprise CMS platform, indicating a mature and scalable infrastructure. It uses JavaScript extensively for UI interactions and multimedia content delivery, including HLS streaming for video. Analytics are handled via Matomo, an open-source privacy-focused tool, and Google reCAPTCHA is used for bot mitigation. The site structure is well-organized with clear navigation menus and semantic HTML elements. Performance is moderate, likely due to the complexity of SharePoint and multimedia content. SEO is supported by comprehensive meta tags and Open Graph data. The site is mobile responsive with basic accessibility features, though improvements are possible. Hosting details are not explicit but likely managed by a government or institutional provider. Overall, the technical stack supports the organization's needs effectively with room for modernization in some areas.
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.
