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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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';…

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

Business profile

SUNfarming holds a leadership position in the agri-photovoltaic sector in Germany, leveraging over two decades of experience and a portfolio of approximately 700 MW solar projects. Its business model integrates renewable energy development with sustainable agricultural practices, promoting dual land use. The company benefits from its affiliation with Cube Green Energy Group, enhancing its market reach and resource base. Key competitive advantages include a fully integrated service platform covering development to asset management, strong partnerships with farmers, and recognized industry awards. The target customers range from agricultural enterprises to private homeowners seeking solar solutions. Recent news and active project updates indicate ongoing growth and innovation. The partnership ecosystem includes reputable organizations and funding bodies, reinforcing operational stability.

Security posture

The website exhibits a solid security foundation with HTTPS encryption and cookie consent mechanisms aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security policies, incident response contacts, and a security.txt file suggests room for improvement in transparency and readiness. Security headers are not explicitly observed, which could enhance protection against common web attacks. The use of reputable WordPress plugins and absence of WAF blocking indicate a balanced security approach. Overall, the security posture is good but could be elevated by formalizing policies and improving header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Enhance website security headers including Content-Security-Policy and X-Frame-Options.
  5. Improve accessibility features to meet higher standards for inclusive user experience.

Technical notes

Notes

The website is powered by WordPress CMS with a modern tech stack including jQuery, Slider Revolution for dynamic content, and Borlabs Cookie for privacy compliance. The site is responsive and optimized for mobile devices, with good SEO practices such as meta descriptions and hreflang tags for multilingual support. Performance is moderate, with potential for optimization in loading speed. Hosting provider details are not explicit but the domain uses multiple authoritative name servers. The technical infrastructure supports a professional and scalable online presence, though accessibility and security header enhancements are recommended to reduce technical debt and improve 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.
