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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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"

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

The company operates a B2B and B2C business model, providing products and services related to renewable energy heating solutions. It maintains a professional ecosystem with registered business partners and offers extensive product catalogs and training. The website's multi-language structure and partner domains indicate a broad European market presence. The business model leverages direct sales, professional partnerships, and after-sales services, positioning STIEBEL ELTRON as a trusted energy solutions provider in Hungary and neighboring markets.

Security posture

The website enforces HTTPS and employs a cookie consent mechanism compliant with GDPR. Analytics are managed via Piwik PRO with anonymization features enabled, reflecting a privacy-conscious approach. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident, and no public security policy or incident response contacts are provided. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be enhanced by publishing security policies and adding recommended HTTP headers.

Recommendations

  1. Publish a dedicated security policy or security.txt file to improve transparency and incident response readiness.
  2. Implement and enforce additional security headers such as Content-Security-Policy and X-Frame-Options to mitigate common web attacks.
  3. Provide explicit incident response contact information (e.g., security@ or abuse@ email addresses) on the website.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.
  5. Enhance accessibility features and provide a clear terms of service page to improve compliance and user trust.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, utilizing RequireJS for JavaScript module loading and Piwik PRO for analytics and tag management. The site is mobile-optimized with responsive design and includes SEO best practices such as meta tags and Open Graph data. Performance is moderate, with lazy loading of images and asynchronous script loading. The technical stack is modern and well-implemented, though opportunities exist to improve accessibility and security header implementation. Hosting provider details are not explicitly available from the HTML content.
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.
