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 · found on this site
  • 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

Uniper's market position is strong in the European energy sector with diversified services including power generation, gas storage, and energy trading. Their business model leverages both traditional and renewable energy sources, targeting industrial and utility customers. The company invests heavily in growth and transformation to support decarbonization goals. Their digital ecosystem includes related domains for digital services and storage portals, indicating a broad service offering. The website content and structure support clear communication to stakeholders and customers, reinforcing trust and professionalism.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of security headers, and integration of captcha for form protection. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit incident response contacts and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security posture is solid but could be enhanced by publishing dedicated security contacts and disclosure policies.

Recommendations

  1. Publish explicit incident response and security contact information on the website.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Enhance transparency around security frameworks and certifications adopted.
  4. Regularly audit third-party scripts and analytics for privacy compliance.
  5. Maintain and update WHOIS information to improve domain trust signals.

Technical notes

Notes

The website uses Drupal 10 CMS with Bootstrap for responsive design, ensuring excellent mobile optimization and accessibility. Analytics are handled via Piwik PRO, and captcha services are integrated for form security. The site loads with moderate performance, likely due to rich media content and extensive navigation structure. The technical implementation is modern and follows best practices, with valid HTML/CSS and SEO-friendly meta tags. Opportunities exist to optimize performance further and enhance security transparency.
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.
