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

STIEBEL ELTRON Italia is a localized website for the German-based STIEBEL ELTRON GmbH & Co. KG, a well-established company specializing in energy-efficient building solutions such as heat pumps, thermal storage, and ventilation systems. The company has a strong international presence with multiple production sites and subsidiaries, targeting building professionals and homeowners in Italy. The website reflects a professional and consistent brand image with comprehensive content and clear navigation. Technically, the website uses modern JavaScript libraries and analytics tools, including RequireJS, Modernizr, and Piwik PRO, and is likely built on Adobe Experience Manager CMS. The site is mobile-optimized and performs moderately well, with good SEO and basic accessibility features. Security best practices such as HTTPS enforcement and cookie consent mechanisms are implemented, though some security headers could be improved. The security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is strong, with clear privacy and cookie policies and a consent mechanism aligned with GDPR requirements. However, explicit security policies and incident response contacts are not found, which could be enhanced. Overall, the website presents a low-risk profile with high business credibility and good technical maturity. Strategic recommendations include enhancing security headers, improving accessibility, and publishing explicit security and incident response policies to further strengthen trust 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

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. 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

  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 operates in the renewable energy sector, focusing on heating and ventilation solutions for residential and commercial buildings. The company leverages German engineering and has a global footprint with subsidiaries and production sites worldwide. The Italian website targets local customers and partners, offering product information, training, and customer support. The business model centers on manufacturing and distributing energy-efficient systems, supported by digital tools and training programs. The company maintains a strong brand presence and trust signals through privacy compliance and social media engagement. Growth indicators include ongoing product installations and training initiatives. The partnership ecosystem is broad, with multiple country-specific domains linked from the site.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure cookie settings. Analytics are configured with anonymization options, and a cookie consent banner is present, indicating GDPR awareness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, some security headers like Content-Security-Policy and X-Frame-Options are not explicitly observed and should be implemented to mitigate risks such as clickjacking and cross-site scripting. Incident response and security policy information are absent, which could impact readiness and transparency. Overall, the site aligns well with common security best practices but has room for improvement in header configuration and incident response visibility.

Recommendations

  1. Implement Content-Security-Policy and X-Frame-Options headers to enhance protection against common web attacks.
  2. Publish explicit security policies and incident response contact information to improve transparency and readiness.
  3. Enhance website accessibility features to meet higher compliance standards and improve user experience for all users.
  4. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues arise.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built on a modern technology stack including RequireJS for module loading, Modernizr for feature detection, and Owl Carousel for UI components. It uses Piwik PRO for analytics with tag management and anonymization features, indicating a focus on privacy-aware data collection. The CMS appears to be Adobe Experience Manager, inferred from URL patterns and JCR content references. Performance is moderate with some lazy loading and preload optimizations. Mobile optimization is good, with responsive images and adaptive layouts. SEO is well addressed through meta tags and Open Graph data. Accessibility is basic but could be improved. No major technical debt or risks are evident, though security header enhancements are recommended.
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.
