Risk levelMedium

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

Viessmann Climate Solutions operates as a leading global provider of sustainable climate technology solutions, specializing in heating, cooling, ventilation, water and air quality, and renewable energy systems. The company is part of Carrier Global Corporation and has a strong market presence with a comprehensive portfolio of products and digital services. The website is professionally designed, content-rich, and targets both B2C and B2B customers in Poland and beyond. Technically, the site uses modern web technologies including Adobe Experience Manager CMS, lazy loading, and consent management tools, ensuring good performance and compliance with privacy regulations. Security posture is strong with HTTPS, security headers, and no visible vulnerabilities, though explicit security policies and incident response information are not publicly available. The absence of WHOIS data reduces domain registration transparency but does not detract from the overall legitimacy indicated by the website content and branding.

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.

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

Viessmann Climate Solutions holds a strong position in the energy sector, focusing on climate-friendly and renewable energy technologies. Their business model integrates manufacturing with digital services and partner ecosystems, including trade partners and installers. The company targets residential and commercial customers seeking energy-efficient heating and cooling solutions. The website supports this with detailed product catalogs, financing options, expert consultations, and partner portals. The presence of multiple external partner domains and social media channels indicates a mature and well-connected business operation.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and consent management for cookies, aligning with GDPR requirements. However, there is no publicly available security policy or incident response contact information, which are recommended best practices. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses reputable third-party services for analytics and consent management, minimizing risk. Overall, the security maturity is good but could be enhanced by publishing explicit security and incident response policies.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate reporting of security issues.
  3. Implement and publish a vulnerability disclosure program or security.txt file.
  4. Add explicit contact details for the Data Protection Officer to enhance GDPR transparency.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Notes

The website is built on Adobe Experience Manager, leveraging modern web technologies such as lazy loading for images and videos, and uses Usercentrics for consent management and Google Tag Manager for analytics. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with room for improvement in loading speed. The technical infrastructure supports a professional and scalable digital presence suitable for an enterprise-level company. No critical technical debt or risks were identified, but ongoing monitoring of third-party dependencies is advised.
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.
