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

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

CNES operates as a government agency with a clear mandate to manage and operate France's space programs. Its business model is non-commercial, focusing on public service and scientific advancement. The website reflects this with no advertising or commercial tracking. The agency's partnerships include European and international space organizations, and it maintains a strong presence in education and public outreach. The domain's long history and consistent registration data reinforce its credibility. The site’s content and structure support strategic communication and stakeholder engagement, with dedicated sections for various audiences including students, scientists, and enterprises.

Security posture

The website demonstrates a good security maturity level with HTTPS and privacy-respecting analytics (Matomo Cloud). Cookie consent is actively managed via Tarteaucitron. No security headers were explicitly detected in the HTML content, and no direct contact information for security incidents is published, which are areas for improvement. There is no evidence of exposed sensitive data or vulnerable libraries. The absence of a published security policy or vulnerability disclosure program suggests room to enhance transparency and incident readiness. Overall, the security posture is solid but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Implement and configure security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide explicit contact channels for security incidents, such as security@ or abuse@ email addresses.
  5. Continue to monitor and minimize third-party tracking and ensure all scripts are up to date.

Technical notes

Notes

The website is built on Drupal CMS with integration of the French government design system (DSFR) ensuring compliance with accessibility and usability standards. It uses modern JavaScript libraries and privacy-focused analytics (Matomo Cloud). Performance is moderate with responsive design and mobile optimization rated excellent. The site uses Tarteaucitron for cookie consent management, reflecting good privacy practices. Hosting appears to be managed by reputable French academic and research networks, consistent with the agency's profile. Opportunities exist to improve technical security by adding security headers and formalizing security policies.
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.
