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

Heckert Solar Shop is a German-based specialized provider of photovoltaic (PV) modules, inverters, and storage solutions targeting both private consumers and business customers. The company offers a comprehensive product range including solar modules, balcony power plants, inverters from multiple brands, PV storage systems, commercial storage, mounting systems, e-mobility products, and accessories. The website is professionally designed, mobile-optimized, and built on the Shopware CMS platform, indicating a mature digital infrastructure. The presence of multiple advertising and tracking technologies such as Google Analytics 4, Facebook Pixel, and various ad networks reflects an active marketing strategy. However, the absence of WHOIS data for the domain raises concerns about domain registration legitimacy, which should be verified. The website lacks explicit privacy policy and terms of service pages, though it implements a cookie consent mechanism. Security posture is generally good with HTTPS enforced but could be improved by adding security headers and publishing security policies. Overall, the site presents a trustworthy and professional front for a medium-sized energy sector business in Germany.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  4. GDPR outside view

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

    • 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

    • 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

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

The company operates in the energy sector focusing on solar technology products and services. Its business model combines e-commerce sales with B2B and B2C services including planning, consulting, and training. The target audience includes end consumers, specialized partners, commercial clients, and project developers. The product portfolio is broad and includes well-known brands, indicating strong supplier relationships. The website's content and navigation support a positive user experience and facilitate product discovery. The lack of visible company contact details and absence of WHOIS data may impact customer trust and should be addressed. The company appears to be positioned as a specialized, reliable provider within the German solar market.

Security posture

The website enforces HTTPS and uses standard tracking and advertising scripts. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. There is no visible security policy or incident response contact information, which are important for compliance and trust. The cookie consent mechanism is implemented, supporting privacy compliance. Overall, the security posture is moderate but could be enhanced by implementing recommended headers and publishing security-related policies.

Recommendations

  1. Verify and update WHOIS domain registration information to ensure transparency and trust.
  2. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer.
  3. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to improve security posture.
  4. Add clear contact information for security incidents and consider publishing a vulnerability disclosure policy or security.txt file.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on the Shopware CMS platform and uses a modern JavaScript stack including jQuery and various Shopware-specific scripts. It integrates multiple third-party services such as Google Tag Manager, Facebook Pixel, and Cookie Script for analytics and marketing. The site is mobile-optimized and has good SEO metadata including Open Graph and Twitter card tags. Performance is moderate with deferred loading of scripts. No major technical debt or outdated libraries were detected in the provided HTML content. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports a professional e-commerce experience but could benefit from enhanced security configurations.
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.
