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

Duha is a Czech non-profit organization dedicated to providing leisure, nature, and recreational activities for children and youth. The organization operates through local branches across the country, offering camps, outdoor sports, cultural activities, and volunteer opportunities. Their focus on experiential pedagogy and community engagement positions them as a well-established entity in the youth non-profit sector. The website content is rich with event reports, news, and information about their programs, targeting children, youth, and volunteers. Technically, the website uses standard web technologies such as Bootstrap and jQuery, with a moderate level of mobile optimization and accessibility. However, there is no evidence of advanced CMS or hosting details. The site lacks privacy and cookie policies, and no security headers or HTTPS status information was detected from the provided data, indicating room for improvement in security and compliance. From a security perspective, the absence of WHOIS data reduces transparency, though this is likely due to privacy protection common among non-profits. No forms or sensitive data collection mechanisms were found, reducing immediate risk. The site does not display any signs of WAF or blocking mechanisms, and content is fully accessible. Social media presence and partner logos add to the trustworthiness of the organization. Overall, the website is functional and informative but requires enhancements in security posture, privacy compliance, and transparency to improve trust and protect user data. Strategic improvements in these areas will strengthen the organization's digital maturity and stakeholder confidence.

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

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. Security headers

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

Duha operates in the non-profit sector focused on youth and community engagement in the Czech Republic. Its competitive advantage lies in its experiential pedagogical approach and broad network of local branches offering diverse outdoor and cultural activities. The business model is service-oriented, relying on volunteer participation, grants, and partnerships with foundations and government bodies. Revenue streams likely include donations, grants, and event fees. The target customers are children, youth, families, and volunteers interested in outdoor recreation and social projects. The presence of partner logos from reputable organizations indicates a strong partnership ecosystem. Growth indicators include active event reporting and social media engagement. The organization appears stable with a medium size and consistent branding.

Security posture

The current security maturity level is basic. The website lacks visible HTTPS enforcement and security headers, which are critical for protecting user data and preventing common web attacks. No privacy or cookie policies are published, indicating compliance gaps with GDPR and related regulations. No incident response or security contact information is provided, limiting readiness for security events. The absence of forms reduces attack surface but also limits user engagement features. No known vulnerabilities or exposed sensitive data were detected. The security culture appears minimal, with no explicit security frameworks or certifications mentioned. Improvements in SSL configuration, security headers, privacy compliance, and incident response readiness are recommended to elevate security posture.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with GDPR compliance and implement user consent mechanisms.
  4. Provide clear contact information for security incidents and designate a Data Protection Officer if applicable.
  5. Regularly update all third-party libraries and frameworks to mitigate vulnerabilities.

Technical notes

Notes

The website is built using Bootstrap and jQuery, indicating a traditional front-end stack suitable for responsive design. Google Fonts are used for typography. The site structure is clear with a navigation bar and content sections. No advanced CMS or backend technologies were detected. Performance appears moderate with no explicit optimization indicators. Mobile optimization is basic but functional. Accessibility features are minimal but present. SEO optimization is basic with meta viewport and charset tags but no Open Graph or JSON-LD structured data found. The site lacks modern security and privacy features, which should be addressed to reduce technical debt and improve user trust.
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.
