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 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 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

The company holds a strong market position as a regional energy and transportation provider with multiple subsidiaries covering various aspects of utility and infrastructure services. Its business model focuses on sustainable energy supply and public mobility solutions, targeting both residential and commercial customers in the Bonn region. The presence of multiple related domains and certifications like 'Charta der Vielfalt' and CO2-neutral website certification indicate a well-established corporate structure and commitment to social responsibility. The company leverages digital channels for customer engagement and recruitment, supporting growth and operational efficiency.

Security posture

The website demonstrates good security hygiene with enforced HTTPS, use of Google reCAPTCHA to protect forms, and a cookie consent mechanism aligned with GDPR. However, the absence of published security policies, incident response contacts, and security.txt files suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analysis. Enhancing HTTP security headers and providing clear security governance information would strengthen the security posture further.

Recommendations

  1. Publish a formal security policy and incident response information on the website.
  2. Implement and expose a security.txt file to facilitate vulnerability disclosures.
  3. Enhance HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Increase transparency around data retention policies and privacy compliance.

Technical notes

Notes

The website uses TYPO3 CMS, a robust and widely used content management system, ensuring scalability and maintainability. Integration of Google Tag Manager and reCAPTCHA indicates modern marketing and security practices. The site is mobile optimized with good accessibility and SEO features. Performance is moderate, with potential improvements in loading speed and resource optimization. The technical stack is appropriate for a large utility company, but ongoing modernization and security hardening are recommended to maintain operational resilience.
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.
