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

3 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

ENTSO-E operates as a non-profit association essential to the European energy sector, providing regulatory coordination, data services, and policy recommendations. Its market position is authoritative within the electricity transmission domain, supported by extensive publications, consultations, and stakeholder engagement. The business model centers on collaboration among transmission system operators and regulatory bodies. The website's content and external links indicate a mature partnership ecosystem and a focus on transparency and innovation. Growth indicators include active consultations and project submissions. The organization targets energy professionals, regulators, and researchers, emphasizing strategic influence rather than commercial revenue streams.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, no visible sensitive data exposure, and privacy-conscious analytics configuration. However, it lacks publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for transparency and trust. No security headers were detected in the provided data, suggesting room for improvement. The absence of phone contact and physical address on the homepage reduces direct contact options but is consistent with a European association model. Overall, the security posture is good but could be enhanced by publishing formal security and incident response documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response and vulnerability disclosure contacts to improve transparency.
  3. Implement a cookie consent banner/mechanism to comply fully with EU cookie regulations.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Consider publishing data protection officer contact details to enhance GDPR compliance.

Technical notes

Notes

The website uses a modern and performant tech stack with custom web fonts and asynchronous JavaScript loading. Matomo analytics is used with privacy features enabled, reflecting a commitment to user privacy. The site is mobile optimized with responsive design and good accessibility features. SEO is supported by proper meta tags and structured navigation. No CMS or hosting provider information was detected. Performance is moderate, with potential for optimization in loading times. The site structure is clear and well-organized, supporting a positive user experience. Technical risks are minimal, but adding security headers and formalizing security documentation would reduce potential vulnerabilities.
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.
