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

Donio.cz is a Czech crowdfunding platform established in 2019 that enables users to create fundraising campaigns and donation collections free of charge. The platform targets a general audience in the Czech Republic, focusing on non-profit and charitable causes. The website is professionally designed with excellent content quality and clear navigation, optimized for mobile devices. Technically, the site uses modern JavaScript libraries, Google Tag Manager for analytics, Sentry for error tracking, and Cookiebot for cookie consent management. Hosting and DNS services are provided by Cloudflare, ensuring good performance and security. Security posture is solid with HTTPS enforced and cookie consent implemented, though the absence of explicit privacy policies, terms of service, and security headers indicates room for improvement. No contact information or incident response channels are explicitly provided, which may impact user trust and compliance. Overall, the domain registration data aligns well with the website content, supporting legitimacy and trustworthiness.

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 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Business profile

Donio.cz operates as a regional crowdfunding platform in the Czech Republic, offering free and transparent fundraising services where 100% of collected funds are passed to campaign owners. The business model is based on facilitating social and charitable campaigns, targeting individuals and organizations seeking to raise funds for meaningful causes. The platform's competitive advantage lies in its no-fee policy and user-friendly interface. The company appears to be medium-sized with a focus on non-profit sectors. The website content and branding are consistent and professional, supporting a trustworthy image. Partnerships or subsidiaries are not explicitly identified. The platform leverages third-party services for analytics and cookie management, indicating a mature digital ecosystem.

Security posture

The website enforces HTTPS and uses Cloudflare DNS, providing a secure transport layer. Cookie consent is managed via Cookiebot with blocking mode enabled, demonstrating compliance with cookie regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No vulnerability disclosure or security.txt files are present, and no incident response contacts are provided, which limits transparency and readiness for security incidents. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is moderate but could be enhanced by implementing additional security headers and publishing security policies.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information including emails and phone numbers for general inquiries and security incidents.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced and maintain compliance with GDPR and other regulations.

Technical notes

Notes

The website uses a modern JavaScript-based frontend with integration of Google Tag Manager for analytics and Sentry for error monitoring. Cookiebot is used for cookie consent management with blocking mode enabled, indicating a focus on privacy compliance. Hosting and DNS are managed via Cloudflare, which likely provides CDN and DDoS protection. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with potential improvements possible through optimization of scripts and assets. No CMS was explicitly detected from the HTML content. The site lacks some security headers which could be added to improve security posture. Overall, the technical infrastructure is solid and supports the business needs effectively.
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.
