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

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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 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';…

  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.

Add-on

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

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 targets private investors seeking to invest in European renewable energy infrastructure with a strong ESG and impact focus. The business model centers on managing an open infrastructure fund (QEEE) that invests primarily in wind, solar, and water energy projects. The partnership with EB-SIM enhances asset management capabilities. The website content and structure indicate a small-sized, specialized firm with a clear market niche. The absence of phone numbers and physical addresses on the site suggests a focus on digital contact via email. The company leverages regulatory frameworks such as the EU Disclosure Regulation to build investor confidence. The partnership ecosystem includes Doric and EB-SIM, reinforcing operational and risk management strengths.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism aligned with GDPR requirements. Use of Matomo analytics is privacy-conscious. However, the absence of explicit security policies, incident response information, and security headers like Content-Security-Policy or X-Frame-Options indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is good but could be enhanced by publishing formal security documentation and adding security headers. Incident response readiness is not publicly documented, which could impact trust in case of security incidents.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Consider implementing and publishing a vulnerability disclosure policy or security.txt file.
  4. Include more comprehensive contact information such as phone numbers or physical addresses to enhance trust.
  5. Regularly audit and update third-party libraries and scripts to ensure no vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible open-source content management system. It uses Matomo for analytics, which is self-hosted and privacy-friendly. The site loads CSS and JavaScript assets efficiently and includes a cookie consent mechanism. Mobile optimization is good, and SEO meta tags are properly set. Hosting provider details are not explicitly available from the HTML content or WHOIS data, but DNS name servers indicate professional DNS management. Performance is moderate, with no obvious technical debt or deprecated technologies. Opportunities exist to improve accessibility and security headers to enhance overall technical robustness.
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.
