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

Zeffy, inc. operates a leading 100% free fundraising platform targeted at nonprofit organizations across North America. The platform offers a comprehensive suite of fundraising tools including ticketing, donations, peer-to-peer campaigns, eCommerce, raffles, auctions, memberships, donor management, and in-person payment acceptance via Tap to Pay. Zeffy’s unique business model relies exclusively on optional tips from donors, allowing nonprofits to keep 100% of the funds raised. The company has established a strong market position with over 50,000 organizations using its services and holds a B Corp certification, underscoring its commitment to social impact. Technically, Zeffy’s website is built on Webflow CMS and hosted via Cloudflare, integrating multiple modern analytics and marketing technologies such as Amplitude, Microsoft Clarity, Hotjar, Facebook Pixel, and HubSpot. The site supports multilingual content through Weglot and employs advanced user tracking and A/B testing frameworks. While the website design, content quality, and user experience are excellent, performance is somewhat slow, and accessibility is basic. From a security perspective, the site has significant shortcomings. The SSL certificate is invalid or missing, resulting in no HTTPS enforcement and no modern TLS protocols enabled. Security headers are minimal, with only SPF and DMARC configured for email protection. No HSTS, OCSP stapling, or session resumption mechanisms are in place, and certificate transparency compliance is lacking. These issues substantially reduce the security posture and expose the site to potential risks. Overall, Zeffy presents a highly credible and professional platform with strong privacy compliance and user trust signals. However, the critical lack of proper SSL/TLS configuration is a major security concern that should be addressed promptly to protect user data and maintain trust. Strategic recommendations include fixing SSL deployment, enabling modern security protocols, and enhancing security headers and monitoring.

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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Zeffy is positioned as a disruptive player in the nonprofit fundraising sector, offering a zero-fee platform that appeals strongly to cost-conscious organizations. Its revenue model based on optional donor tips is innovative and sustainable, evidenced by a large and growing user base. The company leverages partnerships with major payment processors like Stripe and PayPal, positioning itself as a competitive alternative. The platform’s extensive feature set addresses diverse fundraising needs, from events to memberships and eCommerce, enabling broad market penetration. Zeffy’s marketing and analytics investments indicate a data-driven growth strategy, while its B Corp certification enhances brand reputation. The multilingual support and targeted fundraising tips content suggest a focus on North American and bilingual markets. Overall, Zeffy demonstrates strong operational maturity and market insight, with opportunities to expand through enhanced security and technical optimization.

Security posture

The current security posture of Zeffy’s website is moderate to poor due to critical SSL/TLS misconfigurations. The absence of a valid SSL certificate and lack of HTTPS enforcement expose users to risks such as data interception and man-in-the-middle attacks. While email security is addressed with SPF and DMARC records, other security best practices like HSTS, OCSP stapling, and session resumption are missing. The site does not exhibit signs of vulnerable libraries or exposed sensitive data in the HTML content. Privacy compliance is strong, with a comprehensive cookie consent mechanism and GDPR-aligned policies. Incident response and security policy documentation are not evident, indicating potential gaps in security governance. The use of multiple third-party analytics and marketing tools increases the attack surface, necessitating vigilant monitoring. Immediate remediation of SSL issues and enhancement of security headers are essential to elevate the security maturity and protect stakeholder data.

Recommendations

  1. Urgently fix SSL certificate deployment to enable HTTPS and secure communications.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated versions.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Enable OCSP stapling and session resumption to improve SSL performance and security.
  5. Develop and publish a formal security policy and incident response plan accessible to users.
  6. Conduct regular security audits and vulnerability assessments, especially for third-party integrations.
  7. Enhance accessibility features to improve compliance and user experience for all users.
  8. Maintain transparency on data retention policies and update privacy documentation accordingly.
  9. Optimize website performance to reduce load times and improve user engagement.
  10. Leverage trust signals further by displaying certifications and security badges prominently.
Technical notes

Notes

Zeffy’s technical infrastructure is modern and leverages a robust tech stack centered on Webflow CMS, Cloudflare hosting, and a suite of analytics and marketing tools including Amplitude, Microsoft Clarity, Hotjar, and Facebook Pixel. The site supports multilingual content via Weglot and employs advanced user tracking and A/B testing frameworks. However, the website suffers from slow load times (18.4 seconds) and a large page size (~1.9 MB), indicating potential optimization opportunities. The absence of a valid SSL certificate and disabled TLS protocols represent critical technical risks. The site is mobile-optimized with good responsive design but has basic accessibility features. SEO is well addressed with proper meta tags and Open Graph data. Overall, the technical setup is solid but requires urgent security fixes and performance tuning to ensure reliability and scalability.
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.
