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

5 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

  3. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  4. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Zewo's market positioning as a trusted certifier of non-profits in Switzerland provides it with a competitive advantage in the charitable sector. Its business model revolves around enhancing donor confidence and supporting NPOs in meeting high standards. Revenue streams likely include certification fees and partnerships. The target customers are donors seeking trustworthy organizations and NPOs aiming for certification. The website's partnership ecosystem includes social media and marketing tools, enhancing outreach. Growth indicators include regular news updates and events like the Zewo-Tagung. Strategic observations highlight the importance of maintaining transparency and expanding digital services to support NPOs and donors.

Security posture

The website exhibits a mature security posture with enforced HTTPS, cookie consent, and no visible sensitive data exposure. Use of third-party tracking scripts is managed with consent, though the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a minor gap. No vulnerabilities or malware indicators were detected. Compliance with GDPR is supported by a comprehensive privacy policy and cookie banner. Incident response and security policies are not publicly disclosed, which could be improved to enhance trust. Overall, the security maturity is good but could benefit from formalized policies and additional headers.

Recommendations

  1. Implement and publish a formal security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance transparency by providing contact details for security incidents or abuse reporting.
  5. Continue improving privacy compliance by detailing data retention policies and user rights.

Technical notes

Notes

The website leverages a robust WordPress CMS with modern front-end frameworks like Foundation and Slick Carousel, ensuring responsive and interactive user experience. Integration with Algolia provides efficient search capabilities. SEO is enhanced via Yoast SEO Premium and structured data (JSON-LD). Performance is moderate, with potential optimization in script loading and caching. Accessibility features are present but could be further audited for compliance. The technical stack is well-maintained, though reliance on multiple third-party scripts necessitates ongoing security vigilance. Hosting details are not explicit, but no performance or uptime issues were detected.
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.
