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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 prominent position as a public research entity in France, with a diversified portfolio spanning energy (nuclear and renewables), defense, digital innovation, and health sciences. Its business model centers on research excellence, technology transfer, industrial partnerships, and support for startups. The organization leverages its governmental backing and extensive expertise to maintain leadership in scientific innovation. The website's content and linked domains indicate a strong ecosystem of research institutes and operational centers. The absence of direct contact emails or phone numbers on the main site suggests controlled communication channels, typical for governmental entities. The presence of social media channels enhances outreach and public engagement. The site supports recruitment and educational initiatives, indicating growth and talent development focus.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCAPTCHA to mitigate automated abuse. Matomo analytics is used, favoring privacy over intrusive tracking. No security incident response or vulnerability disclosure pages were found, which is a common gap but recommended for transparency. The lack of explicit security headers like Content-Security-Policy or X-Frame-Options is a minor weakness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses SharePoint, which requires regular patching to avoid known vulnerabilities. Overall, the security posture is solid but could benefit from enhanced header policies and published incident response information.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear vulnerability disclosure and incident response policy to improve transparency and trust.
  3. Enhance mobile optimization and accessibility compliance to improve user experience for all visitors.
  4. Regularly audit and update SharePoint and all dependencies to mitigate potential vulnerabilities.
  5. Consider providing verified contact information for security and general inquiries to facilitate communication.

Technical notes

Notes

The website is built on Microsoft SharePoint, leveraging its content management and collaboration features. It uses JavaScript libraries including HLS.js for adaptive video streaming and Matomo for analytics, indicating a focus on multimedia content and privacy-aware tracking. Google reCAPTCHA integration helps prevent automated abuse. The site is served over HTTPS with a valid SSL certificate, ensuring secure data transmission. Performance is moderate, with some room for improvement in mobile responsiveness and accessibility. SEO is well addressed with comprehensive meta tags and Open Graph data. The site structure is clear and consistent, supporting good navigation and user experience. Hosting details are not explicitly identified but likely managed by a governmental or institutional provider.
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.
