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

Stiftung Zewo operates as a Swiss non-profit foundation dedicated to certifying charitable organizations with the Zewo quality seal, ensuring donor confidence through adherence to 21 standards. The website serves as a comprehensive platform for donors and NPOs, offering search capabilities, certification information, and educational resources. It holds a strong market position as a trusted certifier within Switzerland's charitable sector. Technically, the site is built on WordPress with modern search integration via Algolia and uses several JavaScript libraries and frameworks to enhance user experience. However, the absence of a valid SSL certificate and HTTPS support is a critical security shortfall, exposing users to potential risks and undermining trust. Security headers are minimal, and no advanced security policies or incident response information is publicly available. Privacy compliance is addressed with a cookie consent mechanism and a comprehensive privacy policy, reflecting GDPR awareness. Overall, the site is professionally designed and content-rich but requires urgent security improvements to align with best practices and protect user data.

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. 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 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.

Business context

Business profile

Zewo's business intelligence reveals a focused niche in non-profit certification, leveraging trust and transparency as competitive advantages. Its business model centers on providing certification services and donor education, supported by a well-structured online presence. The platform targets donors and NPOs primarily within Switzerland, with multilingual support enhancing accessibility. The foundation maintains active social media channels and regularly updates content, indicating engagement and growth orientation. Partnerships with recognized platforms like Microsoft Outlook for mail protection and Algolia for search enhance operational reliability. The absence of visible monetization beyond certification and informational services aligns with its non-profit status. Strategic observations suggest opportunities to strengthen security posture and expand digital trust signals to further solidify market leadership.

Security posture

The current security posture is weak due to the lack of HTTPS and valid SSL certificates, which is a critical vulnerability for any modern website, especially one handling donor information. While some security headers like X-Frame-Options are present, the absence of HSTS, OCSP stapling, and modern TLS protocols significantly reduces the site's defense against common web threats. No public incident response or vulnerability disclosure policies were found, indicating limited transparency in security management. The cookie consent mechanism and privacy policy demonstrate some compliance with data protection regulations, but the overall security maturity is low. This exposes the organization to risks including data interception, phishing, and loss of user trust. Immediate remediation is necessary to protect both the foundation and its users.

Recommendations

  1. Implement a valid SSL/TLS certificate and enforce HTTPS site-wide immediately.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable outdated protocols.
  3. Configure HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Add additional security headers such as Content-Security-Policy and X-Content-Type-Options.
  5. Publish a clear security policy and vulnerability disclosure program to enhance transparency.
  6. Conduct regular security audits and penetration testing to identify and mitigate risks.
  7. Improve accessibility features and mobile optimization for broader user inclusion.
  8. Enhance privacy compliance by detailing data retention policies and DPO contact information.
  9. Optimize website performance to improve load times and user experience.
  10. Maintain consistent branding and trust signals across all digital channels.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO Premium for search optimization, Algolia for advanced search capabilities, and Foundation framework for responsive design. It uses several JavaScript libraries such as jQuery, Slick Carousel, and Selectize.js to enhance interactivity. Hosting appears to be managed via Swiss DNS providers (nine.ch) with mail protection through Microsoft Outlook services. Despite a rich feature set, the site lacks HTTPS, which is a major technical deficiency. Performance metrics are not available, but the large page size and zero load time reported suggest potential performance issues. The site is mobile-optimized and includes accessibility considerations, though these could be improved. SEO is well addressed with proper meta tags, Open Graph, and structured data markup. Overall, the technical infrastructure is solid but requires urgent security upgrades and performance tuning.
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.
