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

1 finding 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • 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.

Business context

Business profile

JUWI operates in the energy sector focusing on renewable energy solutions. Their business model revolves around project development and operational services for wind and solar energy projects, complemented by battery storage solutions. The company serves diverse customer segments including landowners, industrial clients, municipalities, and investors. Their market position is that of an experienced and reputable player in Germany's renewable energy landscape. The website content and structure indicate a mature business with a comprehensive service portfolio and a clear focus on compliance and customer engagement. Partnerships with major platforms like LinkedIn and Facebook for marketing and retargeting are evident, alongside the use of Matomo for analytics, reflecting a balanced approach to data-driven marketing and privacy compliance.

Security posture

The website exhibits a good security posture with HTTPS enforced and a detailed cookie consent mechanism that aligns with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and security headers suggests room for improvement in transparency and defense-in-depth. The use of reputable third-party services like Cookiebot and Matomo indicates a commitment to privacy and security best practices. To enhance security maturity, JUWI should consider publishing a dedicated security policy, providing clear incident response channels, and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Maintain and communicate certifications such as ISO 27001 to strengthen trust and compliance posture.

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system, indicating a stable and scalable infrastructure. Frontend technologies include Tiny Slider for interactive elements and Cookiebot for cookie management and GDPR compliance. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with potential for optimization in loading speed. SEO is well addressed through proper meta tags and structured data (JSON-LD). No hosting provider details were explicitly found, but the domain uses name servers from bw-networx.net, suggesting professional hosting. Overall, the technical stack supports a professional and user-friendly digital experience with opportunities for further modernization and security enhancements.
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.
