0–100, higher is better. How it is calculated

Schleswig-Holstein Netz GmbH operates as a regional energy network operator serving Schleswig-Holstein and parts of Nordniedersachsen in Germany. The company provides essential services including electricity and gas network connections, energy feed-in, and customer support portals. The website is professionally designed, well-structured, and targets both residential and commercial customers in the energy sector. The presence of multiple customer portals and detailed service information indicates a mature digital presence. Technically, the site leverages modern JavaScript frameworks like React, integrates consent management via Usercentrics, and uses analytics tools such as Matomo and Google Tag Manager, reflecting a good level of digital maturity. Security posture is strong with HTTPS enforced, consent mechanisms in place, and no obvious vulnerabilities detected. However, the absence of publicly available WHOIS registration data for the domain www.sh-netz.com raises concerns about domain legitimacy and ownership transparency. This discrepancy should be addressed to improve trust. Overall, the site is a reliable and professional resource for energy network customers but would benefit from clearer domain registration information and enhanced security policy disclosures.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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 is positioned as a key regional player in the energy distribution sector, likely under the umbrella of the E.ON group, as suggested by related domains and middleware URLs. Its business model focuses on infrastructure management and customer service for electricity and gas networks. The website supports multiple customer engagement channels including online portals and contact forms, indicating a customer-centric approach. The integration of a dedicated shop domain suggests diversification into product sales related to energy infrastructure. The company targets a broad customer base including private households, commercial clients, and energy producers. The digital ecosystem is integrated with identity management and API services, reflecting a sophisticated operational infrastructure. Strategic partnerships with E.ON and use of advanced web technologies position the company well for future growth and regulatory compliance.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and modern security headers implied by CSP hash scripts. The use of a consent management platform ensures compliance with GDPR cookie regulations. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness. The missing WHOIS data for the domain is a notable risk factor that could impact trust and domain ownership verification. Overall, the security posture is good but could be improved by publishing detailed security and incident response information and establishing a vulnerability disclosure program.

Recommendations

  1. Publish a clear and accessible security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Verify and update domain WHOIS registration to ensure transparency and trustworthiness.
  4. Enhance website accessibility to meet higher standards for users with disabilities.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and improve privacy compliance.

Technical notes

Notes

The website is built on a modern technology stack including React and Adobe Experience Manager CMS, supported by various client libraries and JavaScript frameworks. It integrates third-party services such as Usercentrics for consent management and Matomo for analytics, indicating a focus on privacy-aware tracking. The site uses Google Tag Manager for marketing and analytics tag management. Performance is moderate with room for optimization, and mobile responsiveness is good. The presence of CSP hash scripts suggests attention to content security policies. Hosting appears to be managed internally or via E.ON group infrastructure, ensuring reliability. Technical risks are minimal but include dependency on multiple external domains and scripts which require ongoing security monitoring.
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.
