VARIOTHERM HEIZSYSTEME GMBH · Energy · Austria

High risk. 10 critical or high findings in GDPR outside view, SSL/TLS and 3 other checks.

Security score

26/100

Risk levelHigh

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

Variotherm Heizsysteme GmbH is an established Austrian company specializing in surface heating and cooling systems for floors, walls, and ceilings, leveraging over 30 years of expertise. Their product portfolio targets contractors, installers, architects, and end customers seeking efficient heating and cooling solutions. The company maintains a professional online presence with multilingual support and a comprehensive product and service offering. Technically, the website is built on TYPO3 CMS served by Apache, with integrated analytics via Matomo and Google Tag Manager. However, the absence of HTTPS and a valid SSL certificate significantly undermines the security posture. While cookie consent mechanisms and privacy policies are in place, the lack of advanced security headers and incident response information indicates room for improvement. Overall, the website is functional and professional but requires urgent security enhancements to protect user data and improve 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

10 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

  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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 · found on this site
  • 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

Variotherm operates in the energy sector, focusing on innovative heating and cooling technologies. Their business model includes manufacturing, distribution, and a partner network for installation and support. The company demonstrates consistent branding and maintains active social media channels to engage customers and professionals. The website content is relevant and well-structured, supporting their market position as a specialized heating system provider in Europe. The presence of multiple language versions and partner domains indicates a broad geographic reach. No parent or subsidiary companies were identified, suggesting an independent medium-sized enterprise.

Security posture

The current security posture is weak due to the lack of HTTPS, no HSTS, and missing critical security headers. The SSL configuration is non-existent, exposing users to potential interception risks. No published security policies or incident response contacts reduce transparency and preparedness. The presence of a suspicious external script domain (svrdntfctn.com) warrants further investigation. Despite these issues, no known vulnerabilities or malware were detected. The website employs cookie consent and privacy policies aligning with GDPR, but overall security hygiene needs significant improvement.

Recommendations

  1. Implement a valid SSL certificate and enforce HTTPS site-wide to secure data in transit.
  2. Enable HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Publish a clear security policy and incident response contact information to enhance transparency and preparedness.
  4. Review and audit all external scripts, especially from less known domains like svrdntfctn.com, to prevent supply chain risks.
  5. Enhance cookie consent mechanisms with detailed data retention policies and user control options to improve privacy compliance.

Technical notes

Notes

The website uses a mature CMS platform (TYPO3) with Apache hosting. The tech stack includes standard web technologies (HTML5, CSS, JavaScript) and integrates Matomo and Google Tag Manager for analytics. Performance metrics are not provided but inferred slow due to zero loadTime/resourceCount data. Mobile optimization is good with responsive design and language toggles. SEO is supported by structured data (JSON-LD) and meta tags. However, the lack of HTTPS and modern TLS protocols is a critical technical debt. The presence of multiple external domains and scripts increases the attack surface and requires careful management.
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.
