Risk levelHigh

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

EBERLE Controls GmbH is a German-based manufacturer specializing in heating, climate, and building technology products. Their offerings include a wide range of thermostats, relays, and smart home compatible devices designed for energy-efficient temperature regulation. The company targets both private and commercial customers, emphasizing quality, reliability, and modern design. Their market position is that of an established medium-sized enterprise with a strong focus on innovation and customer service. Technically, the website is built on TYPO3 CMS and integrates modern web technologies including Usercentrics for cookie consent management. The site is well-structured, mobile-optimized, and provides comprehensive product information and support resources. Performance is moderate with good SEO and accessibility basics in place. From a security perspective, the site enforces HTTPS, uses consent management for cookies, and does not expose sensitive data. However, it lacks explicit security policies and incident response contacts, and could improve by adding security headers and formal documentation. Overall, the security posture is solid but could be enhanced with additional transparency and controls. The overall risk assessment is low with no critical vulnerabilities detected. Strategic recommendations include publishing a formal security policy, providing incident response contacts, enhancing security headers, and maintaining regular audits of third-party scripts to ensure ongoing security 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

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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. 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

  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 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"

    • 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 · 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

EBERLE Controls GmbH operates in the energy sector, focusing on heating and climate control solutions. Their competitive advantage lies in combining traditional heating technology with modern smart home integration, such as Matter WiFi compatibility. The business model centers on manufacturing and direct sales supported by a comprehensive online presence including product catalogs, replacement search tools, and customer support. The company shows growth indicators through recent awards and active participation in trade fairs. Their partnership ecosystem includes digital agencies and consent management providers, enhancing their digital maturity. Strategic observations suggest a focus on innovation, quality, and customer-centric services to maintain and grow market share in a competitive industry.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent managed via Usercentrics. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies and incident response contacts indicates room for improvement in transparency and preparedness. Compliance with GDPR is evident through privacy policies and consent mechanisms. The site would benefit from implementing additional security headers such as Content-Security-Policy and X-Frame-Options to mitigate common web threats. Overall, the security culture appears adequate but could be strengthened by formalizing policies and communication channels.

Recommendations

  1. Publish a formal security policy and make it accessible on the website.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts to minimize vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience.

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.
