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

EDF is a leading French energy company specializing in electricity production and supply, with a strong commitment to decarbonization and sustainable energy solutions. The website serves multiple audiences including individual consumers, businesses, communities, and job seekers, providing comprehensive information and services. The digital infrastructure is built on Drupal 10 with modern analytics and privacy management tools, reflecting a mature and professional technical setup. Security posture is strong with HTTPS and cookie consent mechanisms, though explicit security policies and incident response contacts are not publicly visible. The absence of WHOIS data is likely due to privacy protection and does not detract from the site's legitimacy.

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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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

EDF holds a dominant position in the French energy market, leveraging its extensive infrastructure and brand recognition. The business model focuses on electricity generation, customer service, and innovative energy solutions such as electric mobility. The website ecosystem includes dedicated subdomains for different customer segments and recruitment, indicating a segmented and targeted approach. The company benefits from strong branding consistency and trust signals, including official logos and comprehensive privacy policies. Growth indicators include emphasis on sustainability and digital engagement. Partnerships appear to be internal or closely related entities, reinforcing a cohesive corporate structure.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, cookie consent, and use of reputable third-party analytics and privacy tools. However, the lack of published security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the content. Security headers are not explicitly visible in the provided data, and adding them would enhance protection. Overall, the security posture is good but could be elevated by formalizing policies and communication channels.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add and enforce security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Enhance accessibility compliance from 90% to 100% to meet best practices and legal requirements.
  5. Regularly audit third-party scripts and tracking tools to minimize security and privacy risks.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, ensuring a robust content management framework. Integration with Google Tag Manager, TrustCommander, and Boomerang indicates a focus on analytics, privacy compliance, and performance monitoring. The site is mobile-optimized with responsive images and accessibility features, though some improvements are possible. Performance is moderate, likely influenced by third-party scripts and rich media content. The technical stack is well-chosen for an enterprise-level corporate site, balancing functionality and compliance. Opportunities exist to optimize loading speed and enhance security headers for improved resilience.
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.
