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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

Green Planet Energy operates in the competitive renewable energy market in Germany, leveraging its Greenpeace heritage as a key differentiator. The company offers a broad portfolio of energy products including eco-friendly electricity tariffs, green gas options, and energy solutions for heating and mobility. Their transparent approach, including public disclosure of supplier power plants and independent environmental audits, strengthens customer trust. The business model integrates direct customer supply with political advocacy for the energy transition. Growth indicators include diversified product lines and partnerships with recognized environmental organizations. The company maintains a medium size with a focused sector presence in energy, targeting environmentally conscious consumers and businesses. Their digital ecosystem includes customer portals and interactive price calculators, enhancing customer engagement and service delivery.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and integration of consent management tools like Usercentrics. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of modern JavaScript libraries and deferred script loading contributes to secure and performant user interactions. However, the absence of a publicly accessible security policy and incident response contact limits transparency in security governance. No security.txt file or explicit vulnerability disclosure program was found, which could be areas for improvement. Overall, the site aligns well with GDPR and privacy best practices, reflecting a responsible security culture appropriate for an energy supplier handling customer data.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide explicit incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance transparency around data retention policies and user data handling.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and scalable content management system suitable for enterprise-level sites. It employs modern JavaScript libraries including jQuery 3.7.1, Parsley.js for form validation, and Swiper.js for interactive UI components. FontAwesome is used for iconography, and Usercentrics manages cookie consent, indicating compliance with privacy regulations. The site uses Google Tag Manager and eTracker for analytics and event tracking, integrated with consent mechanisms. Performance is moderate with deferred script loading and responsive design ensuring good mobile optimization. Accessibility features such as ARIA labels and skip links are implemented, supporting inclusive user experience. The technical stack is modern and well-maintained, though hosting provider details are not explicitly identified. Opportunities exist to further optimize performance 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.
