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

SONNENENERGIE is the official professional magazine of the Deutsche Gesellschaft für Sonnenenergie e.V. (DGS), focusing on solar energy topics in Germany. Established since 1975, it serves as a reputable source of information for solar energy professionals and enthusiasts. The website is built on WordPress with modern SEO practices using the Yoast SEO plugin, indicating a mature digital presence. The technical infrastructure includes common libraries such as jQuery and Swiper.js, with good mobile optimization and accessibility features. Security posture is solid with HTTPS enabled and no visible vulnerabilities, though security headers and incident response information are lacking. Privacy compliance is weak due to missing explicit privacy and cookie policies. Overall, the site is professional and trustworthy but could improve transparency and compliance aspects.

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

4 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

    • 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

  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 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.

Dark web exposure

Add-on

Leaked records that mention sonnenenergie.de, from OffSeq Breach.

No leaked records found

Breach holds no records for sonnenenergie.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website targets the renewable energy sector, specifically solar energy, and caters to a German-speaking audience interested in solar technology and policy. Its business model revolves around publishing and disseminating expert content, likely supported by subscriptions or memberships via the DGS. The site benefits from a long-standing market presence and association with a recognized industry organization. There is no evidence of aggressive advertising or tracking, suggesting a focus on content quality and user trust. The lack of explicit contact details and privacy policies may limit user engagement and regulatory compliance. The domain's WHOIS data is minimal but not suspicious, aligning with typical domain registration practices for professional organizations.

Security posture

The website employs HTTPS with a presumably good SSL configuration, uses deferred loading for scripts to optimize performance, and avoids exposing sensitive data in the HTML. However, it lacks visible security headers such as Content Security Policy (CSP), HSTS, or X-Frame-Options, which are recommended best practices. There is no public vulnerability disclosure or incident response information, which could be a gap in security transparency. Forms are present but no detailed analysis of their security was possible due to limited form data in the HTML snippet. Overall, the security posture is adequate but could be enhanced by implementing additional headers and formal security policies.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to improve security posture.
  3. Publish a vulnerability disclosure policy and incident response contact information to enhance transparency.
  4. Include clear contact information such as company emails and phone numbers to improve trust and compliance.
  5. Regularly audit and update all plugins and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using the Gutenberg block editor and Yoast SEO plugin, indicating a modern and SEO-friendly architecture. It uses jQuery and Swiper.js for interactive elements, with scripts deferred to improve load times. The site is mobile optimized and accessible, with structured data (JSON-LD) implemented for SEO and social sharing. Hosting appears to be managed via domaincontrol.com (GoDaddy DNS), a common provider. Performance is moderate, with room for optimization. No major technical debt or outdated technologies were detected, but the absence of security headers and privacy compliance features suggests areas for modernization.
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.
