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

RTE is the French electricity transmission system operator responsible for managing the national high-voltage electricity network. The website presents RTE as a key public service entity ensuring safe, economical, and clean electricity supply across France. It offers extensive information on its missions, projects, data, publications, and subsidiaries, targeting a broad audience including candidates, journalists, investors, suppliers, and local communities. Technically, the site is built on Drupal CMS with Bootstrap framework, uses modern web technologies, and is mobile-optimized. Security posture is strong with HTTPS and cookie consent mechanisms, though explicit security headers and policies are not evident. WHOIS data is unavailable or protected, which slightly impacts trust but the professional presentation and linked subsidiaries support legitimacy. Overall, the site is well-structured, content-rich, and trustworthy for its domain.

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

2 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.

    • 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

  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

RTE holds a dominant position in the French energy sector as the national electricity transmission operator. Its business model focuses on public service, network management, and facilitating the energy transition. The company maintains several subsidiaries and partners, enhancing its operational scope. The website reflects a mature digital presence with comprehensive data sharing, publications, and project transparency. The target customers include energy professionals, government entities, and the general public. The presence of detailed reports and data portals indicates a commitment to transparency and stakeholder engagement. Growth indicators include ongoing projects in renewable energy integration and network modernization.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS and a cookie consent mechanism indicating GDPR awareness. However, the absence of visible security headers such as Content-Security-Policy or Strict-Transport-Security suggests room for improvement. No direct contact channels for security incidents or vulnerability disclosures are found, which could hinder incident response. The use of Matomo analytics shows a preference for privacy-conscious tracking. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is good but could be enhanced by publishing explicit security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide explicit contact information for security incidents and data protection officer details to improve transparency and compliance.
  5. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website uses Drupal CMS with Bootstrap 4.5.0 framework, ensuring responsive design and accessibility. Lazy loading of images via Lazysizes improves performance. Matomo analytics is used for user tracking, favoring privacy over commercial trackers. The site includes multiple CSS components and modular JavaScript, indicating a well-structured front-end. The presence of canonical and hreflang tags supports SEO and multilingual support. Performance is moderate with good mobile optimization. No hosting provider details were found, but the site uses HTTPS with a valid certificate. Technical debt appears low, but adding security headers and explicit privacy documentation would improve the technical maturity.
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.
