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.

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

The company holds a strong market position as a clearing house in the financial and energy sectors, targeting market participants requiring clearing and risk management services. Its business model revolves around providing essential infrastructure services for trading platforms and energy markets. The nearly 20-year history and EMIR authorization provide competitive advantages. The website indicates a focus on innovation and customer service, with multilingual support via an English subdomain. Partnerships with major exchanges and platforms are implied. Growth potential lies in expanding clearing services across European energy markets. The company maintains a professional digital presence but lacks some transparency in privacy and contact details.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and a cookie consent mechanism integrated with Google Tag Manager. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Compliance with GDPR is partially indicated via cookie consent but lacks a formal privacy policy. Overall, the security posture is solid but could be enhanced by publishing comprehensive security and privacy documentation and providing clear incident response channels.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data handling and GDPR compliance.
  2. Add terms of service and user agreements to clarify legal conditions.
  3. Provide clear contact information including emails and phone numbers for customer and security incident reporting.
  4. Implement and publish a vulnerability disclosure policy or security.txt file.
  5. Enhance website accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring good performance and responsiveness. Google Tag Manager is used for analytics and cookie consent management, indicating a structured approach to user tracking and privacy. The site uses Material UI for consistent styling and layout. Performance appears moderate with asynchronous script loading and preloading optimizations. SEO metadata is present but could be expanded for better search visibility. Accessibility is basic but can be improved. Hosting details are not explicit but the site is served over HTTPS with proper security headers. Overall, the technical infrastructure is modern and well-implemented with opportunities for further optimization and compliance enhancements.
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.
