Risk levelHigh

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

Heizungsbau Sprich GmbH is a German small business specializing in customized solutions for heating, sanitation, and ventilation systems, including solar energy installations. The company offers services such as renovation and new installations of heating systems, bathroom renovations, and apprenticeships. The website reflects a professional and consistent brand image, targeting private and commercial customers seeking energy-efficient and sustainable heating and sanitary solutions. Technically, the website is built on WordPress using Elementor and TheGem theme, with SEO optimization via Yoast and standard plugins for contact forms and GDPR compliance. The hosting provider is likely Strato, inferred from plugin usage. Security posture is good with HTTPS enforced, but lacks visible security headers and explicit security policies. No vulnerabilities or suspicious elements were detected. Overall, the website is well-structured, mobile-optimized, and trustworthy, though it could benefit from enhanced security headers and incident response documentation.

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

8 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 positions itself as a regional specialist in the energy sector, focusing on heating and sanitation services with an emphasis on sustainable and renewable energy solutions like solar and heat pumps. Partnerships with recognized brands such as Buderus and Brötje enhance credibility. The business model revolves around service provision, including consultation, installation, and training apprentices. The website content and testimonials indicate a customer-centric approach with good communication and quality execution. Growth potential is supported by ongoing apprenticeship programs and market partnerships. The absence of explicit parent or subsidiary companies suggests an independent operation. The company maintains a professional digital presence with moderate technical sophistication.

Security posture

The website employs HTTPS, ensuring encrypted communication. No security headers were detected in the provided data, which is a potential area for improvement. The use of standard WordPress plugins like Contact Form 7 and GDPR-compliant cookie management indicates attention to privacy compliance. However, there is no visible security policy or incident response information, which could hinder rapid response to security incidents. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is adequate for a small business website but could be enhanced by implementing security headers, publishing security policies, and establishing a vulnerability disclosure process.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and preparedness.
  3. Regularly audit and update all WordPress plugins and themes to mitigate vulnerabilities.
  4. Consider adding a security.txt file and vulnerability disclosure guidelines to encourage responsible reporting.
  5. Enhance accessibility features and conduct periodic performance optimizations to improve user experience and SEO.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor page builder and TheGem theme, which provides a flexible and visually appealing design. The presence of Yoast SEO plugin indicates good SEO practices. The site uses jQuery and LayerSlider for interactive elements. Hosting appears to be with Strato, a reputable German hosting provider. Performance is moderate with lazy loading implemented for images. Mobile optimization is good, ensuring usability across devices. Accessibility is basic but could be improved. No advanced analytics or tracking scripts were detected, indicating minimal user tracking. Overall, the technical infrastructure is solid for a small business but could benefit from enhanced security and accessibility improvements.
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.
