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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

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

Zendesk Foundation positions itself as a socially responsible arm of Zendesk, targeting nonprofits and underserved communities worldwide. Its business model centers on grant giving, volunteering, and software donations, supported by a global network of subsidiaries and offices. The foundation's partnerships and programs indicate a strategic focus on social impact through technology. The website's extensive content, testimonials, and impact reports suggest a well-established operation with strong market positioning in the nonprofit tech support sector. The presence of multiple global offices and contact points supports a large enterprise scale. The foundation leverages Zendesk's brand and resources effectively to enhance credibility and outreach.

Security posture

The website employs HTTPS with strong SSL configuration and includes key security headers such as X-Frame-Options and Strict-Transport-Security. Cookie consent is managed via OneTrust, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, additional headers like Content Security Policy and X-Content-Type-Options could further strengthen security. The use of third-party analytics and marketing scripts is balanced with privacy controls. Incident response and vulnerability disclosure information are not explicitly found, representing an area for potential improvement. Overall, the security posture is strong for a public-facing corporate foundation site.

Recommendations

  1. Implement a comprehensive Content Security Policy (CSP) header to mitigate XSS risks.
  2. Add security headers such as X-Content-Type-Options and Referrer-Policy for enhanced protection.
  3. Publish explicit vulnerability disclosure and incident response policies to improve transparency.
  4. Regularly review and audit third-party scripts to minimize supply chain risks.
  5. Enhance visibility of data protection officer contact information to support GDPR compliance.

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.
