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

Viessmann Clean & Cold Solutions operates as a leading European manufacturer specializing in energy efficient and sustainable cold and cleanroom solutions. Their website showcases a broad portfolio including cold and freezer rooms, total energy solutions, cleanroom solutions, and refrigerated cabinets, targeting industries such as food services, healthcare, convenience stores, and other segments requiring specialized refrigeration. The company positions itself strongly within the energy sector with a large-scale business model supported by the Viessmann Group. Technically, the website is built on the Scrivito CMS platform and integrates modern marketing and analytics tools such as Google Tag Manager, Microsoft Clarity, Pardot, and Usercentrics for consent management. The site is mobile optimized with good SEO practices and a professional design, although some accessibility features could be improved. Performance is moderate with no blocking or WAF detected. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, but lacks visible security headers in the HTML source. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, although the website content and branding are consistent with the Viessmann Group. Overall, the security posture is good but could be enhanced by adding security headers and explicit incident response information. The overall risk assessment is moderate with recommendations to verify domain registration status, implement additional security headers, and maintain compliance with privacy regulations. The website is trustworthy and professional, serving its business audience effectively.

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

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. 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

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

Viessmann Clean & Cold Solutions holds a strong market position as a leading European manufacturer in the energy-efficient refrigeration and cleanroom sector. Their business model focuses on manufacturing and lifecycle services including installation and maintenance, targeting commercial and industrial clients in food services, healthcare, and retail convenience sectors. The company benefits from the backing of the Viessmann Group, enhancing credibility and market reach. Strategic partnerships with companies like Vitec and Epta Finland expand their product offerings. The website reflects a mature digital presence with integrated marketing and analytics tools, indicating a focus on customer engagement and lead generation. Growth indicators include active press releases and an academy for training, suggesting investment in expertise and brand loyalty.

Security posture

The website demonstrates a good security maturity level with mandatory HTTPS and cookie consent management via Usercentrics. The use of reputable analytics and marketing tools is balanced with privacy compliance efforts. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No incident response or security policy pages were found, which limits transparency and readiness communication. The missing WHOIS data for the domain is a notable concern, potentially indicating privacy protection or registration issues. Overall, the site is secure for typical business use but would benefit from enhanced header implementation and documented security policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish explicit security policy and incident response information to improve transparency and preparedness.
  3. Verify and document domain registration details to ensure legitimacy and trustworthiness.
  4. Conduct regular audits of third-party scripts and marketing tools to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built using the Scrivito CMS platform, leveraging modern JavaScript frameworks and asynchronous loading of analytics and marketing scripts such as Google Tag Manager, Microsoft Clarity, Pardot, and ActOn. The site uses Usercentrics for GDPR-compliant cookie consent management. Performance is moderate with good mobile optimization and SEO metadata including Open Graph and Twitter cards. The site lacks visible security headers in the HTML source, which is a technical debt. Hosting provider details are not explicitly identified. The site uses video backgrounds and responsive images, indicating a modern design approach. Overall, the technical infrastructure supports a professional and scalable digital presence but could be improved by adding security headers and enhancing accessibility.
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.
