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

Heckert Solar Shop is a German-based e-commerce and service provider specializing in photovoltaic modules, storage systems, inverters, and related solar technology products. The company targets a broad audience including private consumers, professional partners, investors, and commercial clients. The website demonstrates a professional and consistent brand presence with a good range of products and services, positioning itself as a reliable expert in the solar energy sector. Technically, the site is built on the Shopware platform, uses modern JavaScript libraries, and integrates multiple advertising and analytics tools, indicating a mature digital infrastructure. Security posture is adequate with HTTPS and domain protection statuses, but lacks advanced DNS security and explicit security policies. Privacy compliance is partial, with cookie consent implemented but no visible privacy or terms policies. Overall, the website is trustworthy and well-maintained but could improve transparency and security 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. 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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. 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 business operates in the renewable energy sector, focusing on solar technology products and services. It leverages an e-commerce model combined with consulting, training, and support services. The company appears to have a medium-sized operation with a well-defined target market in Germany. The product portfolio includes solar modules, inverters, storage solutions, mounting systems, and e-mobility products. The presence of specialized product brands and service offerings suggests a competitive positioning. The website's integration with multiple ad networks and tracking services indicates active marketing efforts. No direct contact information or detailed corporate data was found, which could be improved to enhance customer trust and engagement.

Security posture

The website uses HTTPS with a valid SSL certificate and domain registration protections such as clientDeleteProhibited and clientTransferProhibited statuses, which help prevent unauthorized domain changes. However, DNSSEC is not enabled, which is a recommended security enhancement. No security headers were detected in the provided data, and there is no published security policy or incident response information. The site uses multiple third-party tracking and advertising scripts, which may raise privacy concerns if not properly managed. No vulnerabilities or exposed sensitive data were identified in the analysis. Overall, the security posture is moderate but could benefit from improved security headers, DNSSEC, and transparency about security practices.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  3. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and HSTS.
  4. Provide clear security policy and incident response information, including contact channels for security issues.
  5. Review and optimize third-party tracking scripts to ensure GDPR compliance and minimize privacy risks.

Technical notes

Notes

The website is built on the Shopware CMS platform, utilizing modern JavaScript libraries including jQuery and various Shopware extensions. It integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is mobile-optimized with responsive design and includes accessibility features such as skip links. Performance appears moderate with multiple sliders and media content. The domain is hosted with DNS servers from DomainControl (GoDaddy). There is no evidence of outdated or vulnerable libraries in the provided data. The site uses a cookie consent mechanism, indicating awareness of privacy regulations. Technical debt appears low, but improvements in security headers and DNSSEC would enhance the overall technical robustness.
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.
