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. 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Eneco operates in the energy sector with a strong emphasis on sustainability and climate goals. Their business model revolves around providing renewable energy and related services to both private and commercial clients. The company benefits from a well-established brand and a clear market position in the Netherlands. Partnerships with dedicated news and recruitment domains enhance their ecosystem. Revenue streams likely include energy sales, sustainable energy projects, and consulting. The company’s strategic focus on climate neutrality and biodiversity aligns with growing market demand for green energy solutions. Their digital infrastructure supports scalability and customer engagement through modern web technologies and analytics.

Security posture

Eneco exhibits a mature security posture with enforced HTTPS, robust security headers, and adherence to ISO 27001 standards. No exposed sensitive data or vulnerable libraries were detected in the website content. Privacy policies and cookie consent mechanisms comply with GDPR requirements. However, the absence of a public vulnerability disclosure policy and explicit incident response contact channels suggests room for improvement in transparency and readiness. The use of third-party scripts like Google Tag Manager is managed with privacy compliance in mind. Overall, the security posture supports business continuity and customer trust but could benefit from enhanced incident response visibility.

Recommendations

  1. Publish a dedicated vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  2. Provide explicit incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet higher standards and improve user inclusivity.
  5. Maintain and communicate ongoing security certifications and compliance efforts to strengthen trust.

Technical notes

Notes

The website is built using a modern tech stack including React and Next.js frameworks, integrated with Sitecore CMS for content management. Hosting on Microsoft Azure provides scalability and reliability. Performance is optimized with preloading of CSS and images, asynchronous loading of scripts, and responsive design for mobile devices. SEO is supported by proper meta tags and sitemap inclusion. Accessibility features such as focus outlines and skip links are implemented, though further enhancements could be made. The technical infrastructure reflects a well-maintained and modern digital platform suitable for a large enterprise energy company.
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.
