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, Facebook, Twitter, LinkedIn, YouTube, Google APIs, Google Ads

      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.

    • 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

GRDF operates in the energy sector, specifically in gas distribution, serving a wide range of customers including private individuals, energy suppliers, businesses, and local authorities. Its business model is that of a regulated public utility, with a strong emphasis on ecological transition and renewable gas sources such as biomethane. The company benefits from the backing of ENGIE, a major energy group, enhancing its market position and credibility. The website supports recruitment, customer service, and informational needs, indicating a comprehensive digital strategy. Partnerships and related domains reflect integration within the ENGIE ecosystem.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, multiple security headers, and no exposed sensitive information. The absence of a public vulnerability disclosure policy or security.txt is a minor gap. No incident response contacts are explicitly published, which could be improved. The use of third-party scripts is standard but should be regularly audited. Overall, the security maturity is good for a public utility website, with room for enhanced transparency and formal vulnerability management.

Recommendations

  1. Publish a formal vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  2. Provide explicit incident response contact information on the website for security issues.
  3. Regularly review and audit third-party scripts and libraries to mitigate supply chain risks.
  4. Enhance transparency on security certifications and compliance frameworks if applicable.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and practices.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging JavaScript libraries such as jQuery and Bootstrap for UI components. Google Tag Manager and Google Analytics are used for tracking and analytics, alongside AB Tasty for optimization. The site is mobile responsive and includes accessibility features. Performance is moderate, with potential improvements in load times through optimization of scripts and images. The technical infrastructure appears robust and suitable for a large enterprise public utility website.
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.
