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. 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

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.

Add-on

Leaked records that mention gruenerstromlabel.de, from OffSeq Breach.

No leaked records found

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The organization operates in the energy sector with a focus on sustainability and environmental protection. Its business model revolves around certifying energy tariffs and providing labels that serve as trust signals for consumers and energy providers. The partnership ecosystem includes leading environmental NGOs, enhancing credibility and market reach. The site promotes a tariff comparison portal, indicating a service-oriented approach to facilitate consumer decisions. Growth indicators include active content updates, social media engagement, and a clear focus on expanding renewable energy adoption. The organization's operations are transparent, with clear contact points and no suspicious patterns detected.

Security posture

The website employs HTTPS and uses modern web technologies, reducing exposure to common web vulnerabilities. No sensitive data leakage or vulnerable libraries were detected in the provided content. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident and should be implemented to enhance protection against clickjacking and cross-site scripting attacks. There is no visible incident response or vulnerability disclosure information, which could be improved to demonstrate security maturity. Privacy compliance is strong, with comprehensive privacy and cookie policies and consent mechanisms in place.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Provide explicit incident response contact information to enhance trust and readiness.
  4. Regularly audit and update all WordPress plugins and themes to mitigate potential vulnerabilities.
  5. Enhance monitoring and logging to detect and respond to security incidents promptly.

Technical notes

Notes

The website is built on WordPress with Elementor page builder and uses several plugins including Yoast SEO and TranslatePress for multilingual support. The tech stack is modern and well-maintained, supporting good SEO and accessibility standards. Performance is moderate, with lazy loading and caching mechanisms implied by WP Rocket usage. The site is mobile optimized and uses responsive design principles. Hosting provider details are not explicit, but DNS uses multiple UI-DNS name servers indicating a stable DNS infrastructure. There is room for improvement in security header implementation and possibly performance tuning.
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.
