Bosch Home Comfort is a professional and well-established business specializing in heating, air conditioning, and hot water solutions. The website reflects a strong market position as a leading European provider of smart and energy-efficient comfort solutions. The company targets residential customers globally with localized country sites and offers a comprehensive range of services including commercial and industrial heating solutions. Technically, the website employs modern web technologies including JavaScript frameworks, Google Tag Manager, and privacy consent management, indicating a mature digital infrastructure. Security posture is solid with HTTPS enforcement and privacy compliance, though some security headers and explicit security policies could be improved.

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

3 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.

    • 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

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

Bosch Home Comfort operates in the energy sector focusing on heating and cooling solutions. Its business model includes both B2B and B2C segments, supported by a network of regional partner sites and subsidiaries. The company leverages its strong brand reputation and extensive product portfolio to maintain a leading market position in Europe and globally. The website's multilingual and multi-regional structure supports diverse customer segments. The presence of a vulnerability disclosure page and privacy policies indicates a mature approach to compliance and customer trust. The company benefits from strategic partnerships and a broad ecosystem of related Bosch domains, enhancing its market reach and operational resilience.

Security posture

The website demonstrates a good security posture with HTTPS enabled and privacy consent mechanisms in place. It includes a dedicated vulnerability disclosure page, which is a positive indicator of security awareness. However, the lack of visible security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options suggests room for improvement. No exposed sensitive data or vulnerable libraries were detected. The site uses secure forms and manages user consent effectively. Incident response contact channels are limited to a vulnerability reporting page without explicit email contacts. Overall, the security maturity is good but could be enhanced by publishing a formal security policy and adding security headers.

Recommendations

  1. Implement and enforce security headers like CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy or framework statement on the website to improve transparency and trust.
  3. Provide explicit contact information for the Data Protection Officer or security incident response team.
  4. Add a security.txt file to facilitate vulnerability reporting and improve coordination with security researchers.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.

Technical notes

Notes

The website uses a modern tech stack including JavaScript modules, Web Components (StencilJS), Google Tag Manager, and jQuery. It loads fonts and CSS asynchronously and employs responsive images for performance optimization. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate with room for improvement in loading speed and caching strategies. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not evident from the HTML. Overall, the technical infrastructure is robust and supports a professional user experience.
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.
