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

Hoval Aktiengesellschaft operates as a leading provider of advanced indoor climate control solutions, specializing in heating, ventilation, and energy-efficient systems for a broad range of building types including residential, commercial, and industrial sectors. The company maintains a strong international presence with a well-structured website that clearly communicates its product offerings and corporate philosophy focused on sustainability and energy responsibility. Technically, the website leverages modern web technologies and SAP Commerce platform, supported by Google Tag Manager and OneTrust for privacy compliance. However, the security posture is weakened by an invalid SSL certificate and lack of modern TLS protocol support, which poses risks to user trust and data security. Privacy compliance is robust with clear policies and consent mechanisms in place. Overall, the website reflects a mature digital presence but requires urgent remediation of SSL and TLS issues to enhance security and trust.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Hoval is positioned as a large enterprise in the energy sector, targeting building owners, architects, and HVAC professionals with a comprehensive portfolio of heating and climate control products and services. The business model centers on manufacturing and selling technologically advanced HVAC solutions, complemented by consulting and customer service. The company demonstrates strong branding consistency and trust indicators including social media engagement and detailed corporate information. Partnerships and service domains such as hoval-energyrecovery.com and recruitment platforms indicate a well-integrated ecosystem supporting growth and operational efficiency.

Security posture

The website exhibits basic security best practices including security headers and HSTS, but suffers from critical SSL certificate issues and absence of modern TLS protocols, significantly undermining its security posture. No explicit incident response or vulnerability disclosure policies are found, indicating potential gaps in security governance. The presence of secure cookie flags and CSRF tokens in forms is positive, but overall security maturity is moderate and requires improvements to meet industry standards and compliance requirements.

Recommendations

  1. Immediately replace or renew the SSL certificate to ensure it is valid and trusted by browsers.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) to secure communications.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Publish a clear security policy and incident response plan accessible on the website.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and trust.
Technical notes

Notes

The website is built on SAP Commerce platform with a modern front-end using JavaScript and templating engines. It integrates Google Tag Manager and OneTrust for analytics and privacy management. Hosting appears to be on Microsoft Azure infrastructure. Performance data is unavailable, but the site shows good mobile optimization and SEO practices. Technical debt is indicated by the lack of valid SSL and outdated TLS support, which should be prioritized for remediation to avoid operational risks.
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.
