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

Energiewendegenossenschaft Region Winterthur (ERW) is a Swiss non-profit cooperative focused on enabling members to build their own photovoltaic solar installations in the Winterthur region. The cooperative operates on a cost-covering basis, leveraging member labor to reduce costs and providing expert support in planning, financing, and regulatory processes. With over 300 projects completed, ERW holds a strong local market position supported by partnerships with organizations like swissolar and sicherheits-charta. The website is built on WordPress with the Divi theme and integrates marketing tools such as HubSpot forms. It offers a good user experience with clear navigation and relevant content tailored to its target audience of environmentally conscious individuals interested in solar energy self-construction. Security posture is solid with HTTPS and no exposed sensitive data, though improvements in security headers and incident response documentation are recommended. Privacy compliance is adequate with a comprehensive privacy policy but lacks a cookie consent mechanism. Overall, the website reflects a trustworthy and professional organization with a clear mission and community focus.

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

7 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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
  • 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

ERW's business model centers on a cooperative approach to solar energy adoption, emphasizing member participation in self-building to minimize costs. This model differentiates ERW from commercial solar providers by fostering community engagement and shared labor. The cooperative's market niche is regional, targeting Winterthur and surroundings, with a strong emphasis on sustainability and renewable energy advocacy. Revenue streams likely include material margins and planning fees, while member labor reduces operational costs. The cooperative maintains strategic partnerships with industry bodies like swissolar, enhancing credibility and access to resources. Growth indicators include over 300 completed projects and active event and course offerings. The website supports these efforts by providing educational content, testimonials, and clear calls to action for membership and participation.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML content. Use of nonce tokens in AJAX calls indicates some protection against CSRF attacks. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. There is no visible incident response or security policy documentation, nor a vulnerability disclosure or security.txt file. Privacy compliance is partially met with a detailed privacy policy but lacks cookie consent mechanisms. Overall, the security posture is adequate for a small cooperative but could be improved to meet higher standards and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and ePrivacy regulations.
  3. Publish an incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ email addresses).
  4. Regularly audit and update all plugins, themes, and scripts to mitigate vulnerabilities.
  5. Consider publishing a security.txt file to facilitate responsible vulnerability disclosure.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Divi theme, which provides a flexible and responsive design. It uses jQuery and integrates marketing and analytics tools such as HubSpot and HappyForms. The site loads with moderate performance and good mobile optimization. SEO is supported by proper meta tags and structured navigation. Accessibility is basic but could be enhanced with ARIA roles and better semantic markup. No major technical debt or deprecated technologies were detected. Hosting details are not explicitly identified but the presence of HTTPS and CDN resources suggests a professionally managed environment. Opportunities exist to improve performance and accessibility further.
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.
