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

STIEBEL ELTRON Ireland operates as a regional branch of the established German company STIEBEL ELTRON GmbH & Co. KG, specializing in manufacturing and distributing heat pumps, ventilation systems, electric hot water, and heating products. The website targets homeowners, installers, and partners, providing product information, installer training, and aftersales services. The company has a strong market position in the energy sector with a history dating back to 1924. Technically, the website is built on a modern stack including JavaScript libraries such as RequireJS and Modernizr, with Adobe Experience Manager likely as the CMS. The site is mobile-optimized, well-structured, and uses Piwik PRO for analytics with a comprehensive cookie consent mechanism, reflecting good digital maturity. Security posture is strong with HTTPS enforced and secure form handling, though explicit security headers are not detected. Privacy compliance is robust with a detailed privacy policy and cookie consent. No incident response contacts or vulnerability disclosure pages were found, representing an area for improvement. Overall, the website is professional, trustworthy, and secure with minor recommendations to enhance security headers and incident response transparency. The domain WHOIS data is unavailable, likely due to privacy protection, which is justified for this business type.

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

    • 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

  2. 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

  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
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

STIEBEL ELTRON Ireland benefits from the reputation and resources of its parent company, operating in the renewable energy and heating sector. Its business model combines product manufacturing with strong installer and partner support, including training and aftersales services. The company targets residential and commercial customers seeking energy-efficient heating and ventilation solutions. The website reflects a mature digital presence with multilingual support and localized content. The partnership ecosystem includes multiple country-specific domains, indicating a broad international footprint. Growth indicators include new product launches and training programs. The company maintains a professional brand image with consistent messaging and trust signals such as compliance and privacy policies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure handling of user interactions such as login and contact forms. The presence of a cookie consent popup with granular controls indicates GDPR awareness and compliance. However, the absence of explicit security headers like Content Security Policy and HSTS is a gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of an incident response contact or security.txt file limits transparency in handling security incidents. Overall, the site is secure but could improve by publishing incident response information and enhancing HTTP security headers.

Recommendations

  1. Implement and enforce HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Publish an incident response contact or security.txt file to improve transparency and readiness for security incidents.
  3. Enhance accessibility features to improve compliance with accessibility standards and broaden user inclusivity.
  4. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues arise from external dependencies.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices, ensuring ongoing GDPR compliance.

Technical notes

Notes

The website is built on a modern JavaScript-based front end with asynchronous loading of scripts and use of RequireJS for module loading. The CMS appears to be Adobe Experience Manager, inferred from URL patterns and resource paths. Performance is moderate with lazy loading of images and asynchronous script loading. Mobile optimization is good with responsive images and adaptive layouts. SEO is well addressed with meta tags, Open Graph tags, and hreflang links for multilingual support. Accessibility is basic but could be improved. The use of Piwik PRO analytics indicates a preference for privacy-focused tracking solutions. No major technical debt or legacy technologies were detected.
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.
