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

Viessmann Technologies GmbH operates as a specialized provider of cleanroom and controlled air solutions targeting industries such as healthcare, life sciences, high-tech manufacturing, and indoor growing. The company positions itself as a competent partner for industry-specific cleanroom technology applications, supported by a professional website that highlights their solutions, project management expertise, and references. The website reflects a medium-sized business with a clear affiliation to the Viessmann Group, enhancing its market credibility. Technically, the website is built on the Scrivito CMS platform and integrates modern analytics and marketing tools such as Microsoft Clarity and Pardot. The site is mobile-optimized with good SEO practices and a cookie consent mechanism compliant with GDPR. However, some security headers are not explicitly detected, and the WHOIS data for the domain is missing, which raises concerns about domain registration transparency. From a security perspective, the site enforces HTTPS and employs cookie consent tools, but lacks visible security policy pages or incident response contacts. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of WHOIS data and security headers suggests areas for improvement to enhance trust and compliance. Overall, the website is professional and trustworthy in appearance but would benefit from improved transparency in domain registration and enhanced security header implementation. Strategic recommendations include adding explicit security policies, incident response contacts, and regular third-party script audits to strengthen security posture 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

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 Technologies GmbH leverages its affiliation with the Viessmann Group to serve niche markets requiring cleanroom and climate control solutions. Their business model focuses on B2B engagements with hospitals, life science companies, and industrial clients. The company demonstrates competitive advantages through specialized project management and pre-engineered cleanroom offerings. The website's references and case studies indicate a solid partnership ecosystem and a focus on quality and reliability. Growth indicators include active content updates and social media engagement. However, the lack of transparent WHOIS data may impact trust among new clients or partners.

Security posture

The website exhibits a moderate to good security maturity level with enforced HTTPS and GDPR-compliant cookie consent. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. The lack of a published security policy or incident response contact limits transparency and readiness for security incidents. Compliance with GDPR is indicated but could be strengthened with explicit documentation. Overall, the security culture appears cautious but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  3. Conduct regular audits of third-party scripts and libraries to identify and remediate potential vulnerabilities.
  4. Enhance WHOIS domain registration transparency to build trust with visitors and partners.
  5. Develop a long-term security strategy incorporating continuous monitoring, employee training, and compliance updates.

Technical notes

Notes

The website is built on a modern CMS platform (Scrivito) with integration of advanced analytics and marketing tools such as Microsoft Clarity and Pardot. The site demonstrates good mobile optimization and SEO practices, contributing to a positive user experience. Performance is moderate, with potential for improvement through optimization of media assets and script loading. The absence of explicit hosting provider information limits full infrastructure assessment. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring. Overall, the technical infrastructure supports the business needs but could benefit from enhanced security configurations and performance tuning.
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.
