High risk. 9 critical or high findings in GDPR outside view, Security headers and 3 other checks.

Security score

44/100

Risk levelHigh

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

Stoehr Haustechnik is a small German company operating in the energy sector, specializing in solar technology and building technology services. The website is built on Joomla CMS using the Helix Ultimate template framework and incorporates modern technologies such as Bootstrap, jQuery, and Google Maps API. Usercentrics is used for cookie consent management, indicating some level of GDPR compliance awareness. However, the site lacks explicit privacy policy, terms of service, and visible contact information, which are critical for full compliance and user trust. Security posture is good with HTTPS and CSRF protections in place, but there is room for improvement in transparency and user communication. Overall, the website is functional and moderately professional but would benefit from enhanced compliance documentation and clearer contact channels.

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

9 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

    • 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

  2. 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
  • 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

The company targets residential and commercial customers interested in solar energy solutions within Germany. Its business model focuses on providing installation and consulting services in the solar energy domain. The market position appears local or regional with a focus on energy efficiency and building technology. The website content is basic but relevant, supporting the company's service offerings. There is no evidence of partnerships or subsidiaries from the provided data. The use of Usercentrics for consent management suggests an understanding of regulatory requirements, though implementation is partial.

Security posture

The website employs HTTPS and includes CSRF token usage in AJAX requests, which are positive security indicators. Cookie consent is managed via Usercentrics, supporting privacy compliance. No security.txt or incident response contacts are found, which limits the ability to report vulnerabilities or incidents. No vulnerable libraries or exposed sensitive data were detected in the provided content. Security headers are minimal but include CSRF protections. Overall, the security posture is moderate but could be enhanced with explicit security policies and incident response mechanisms.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the homepage.
  2. Add terms of service and security policy pages to improve transparency and legal compliance.
  3. Include clear and verified contact information such as company email addresses and phone numbers.
  4. Implement a security.txt file to facilitate vulnerability reporting and incident response.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses Joomla CMS with the Helix Ultimate template framework, leveraging Bootstrap and jQuery for responsive design and interactivity. Google Maps API integration suggests location-based services or contact information display. Usercentrics is integrated for cookie consent management, indicating GDPR compliance efforts. The site is hosted on servers indicated by the nameservers your-server.de and second-ns.de. Performance is moderate with deferred script loading and responsive design considerations. Accessibility and SEO optimizations are basic and could be improved with semantic markup and enhanced metadata. The technical stack is modern but could benefit from additional security headers 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.
