0–100, higher is better. How it is calculated

STIEBEL ELTRON South Africa operates as a regional branch of the established German company STIEBEL ELTRON GmbH & Co. KG, specializing in manufacturing and distributing renewable energy solutions including heat pumps, solar systems, and electric heating products. The website targets both consumers and businesses in South Africa seeking sustainable energy and heating solutions, positioning itself as a reputable and experienced player in the energy sector with a history dating back to 1924. Technically, the website employs modern JavaScript frameworks and asynchronous loading techniques, with a likely enterprise CMS backend. It is mobile-optimized and SEO-friendly, with good content quality and clear navigation. The site uses Piwik PRO for analytics, indicating a privacy-conscious approach to user tracking. However, some security headers are missing, and no explicit security or incident response policies are published. The security posture is strong with HTTPS enforced and cookie consent mechanisms in place, but improvements can be made by adding security headers and publishing vulnerability disclosure information. WHOIS data is unavailable, likely due to privacy protection, which is common for corporate domains. The website is fully accessible with no WAF or blocking detected. Overall, the website is professional, trustworthy, and well-maintained, with minor technical and security enhancements recommended to further strengthen its posture and compliance.

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

  2. GDPR outside view

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

    • 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

    • 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

STIEBEL ELTRON South Africa benefits from the strong brand and resources of its German parent company, leveraging decades of experience in renewable energy technologies. The business model focuses on manufacturing and distributing energy-efficient heating and hot water solutions, targeting environmentally conscious consumers and commercial clients. The company maintains a broad product portfolio including heat pumps, solar systems, and electric heaters, supporting a sustainable future. The website reflects a mature digital presence with integrated analytics and social media engagement, supporting marketing and customer outreach. The absence of detailed WHOIS data is offset by clear contact channels and corporate branding, reinforcing legitimacy. Growth potential lies in expanding renewable energy adoption in South Africa and leveraging global expertise.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and secure cookie settings. The presence of a cookie consent popup aligns with privacy regulations such as GDPR. However, the lack of visible security headers like Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or security policy pages were found, which could enhance transparency and preparedness. The use of Piwik PRO analytics suggests a privacy-aware approach to data collection. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be elevated by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are in use.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website uses a modern JavaScript stack including RequireJS and Modernizr, with asynchronous script loading to optimize performance. The CMS appears to be an enterprise-grade system, likely Adobe Experience Manager or similar, supporting multilingual content and complex navigation structures. The site is mobile-optimized with responsive images and adaptive layouts. Analytics are handled via Piwik PRO, indicating a focus on privacy-compliant data collection. Performance is moderate with room for improvement in loading speed and accessibility. No major technical debt or deprecated technologies were detected, but security header implementation is lacking. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
