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

Wikimedia Česká republika is a non-profit organization dedicated to supporting Wikimedia projects such as Wikipedia, Wikimedia Commons, and Wikidata within the Czech Republic. It focuses on community building, educational programs, partnerships with cultural and public institutions, and advocacy for free knowledge. The organization operates as the official Czech chapter of the Wikimedia Foundation, providing a trusted and recognized presence in the region. The website reflects this mission with comprehensive program descriptions, event calendars, and community news, targeting volunteers, educators, and cultural partners. Technically, the website is built on WordPress, leveraging modern JavaScript libraries like Leaflet.js for maps and Flickity for carousels. It integrates Google Analytics and Tag Manager for analytics and uses a cookie consent management platform to comply with privacy regulations. The site is mobile-optimized, accessible, and SEO-friendly, providing a good user experience. From a security perspective, the site enforces HTTPS and uses a consent mechanism for cookies, but lacks explicit security headers such as Content-Security-Policy or X-Frame-Options. No vulnerabilities or exposed sensitive data were detected. WHOIS data is unavailable, which is common for .cz domains, but the website's content and branding strongly indicate legitimacy and trustworthiness. Overall, the site demonstrates a mature digital presence with strong alignment to its non-profit mission, good technical implementation, and a solid security posture. Strategic improvements could include enhancing security headers and expanding transparency around privacy and incident response policies.

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

6 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Wikimedia Česká republika holds a strong position as the official Czech chapter of the Wikimedia Foundation, serving a niche non-profit sector focused on free knowledge dissemination. Its competitive advantage lies in its official status, community engagement, and partnerships with educational and cultural institutions. The business model is non-commercial, relying on donations and grants, with revenue streams likely from fundraising campaigns and partnerships. The target customer segments include volunteers, educators, cultural institutions, and the general public interested in free knowledge. Growth indicators include active event programming and educational initiatives. The partnership ecosystem includes Wikimedia Foundation and local institutions. The organization's operations are transparent and community-focused, with a clear mission and consistent branding.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and no visible sensitive data leaks. The use of a cookie consent platform indicates awareness of privacy compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No incident response or vulnerability disclosure information is provided, which could be a gap in security readiness. The site does not expose vulnerable libraries or insecure forms. Overall, the security posture is solid for a non-profit organization but could benefit from enhanced header policies and documented incident response procedures.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear incident response policy and provide contact channels for security issues to improve transparency and readiness.
  3. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  4. Enhance privacy policy details to explicitly cover data retention and user rights to strengthen GDPR compliance.
  5. Consider adding terms of service and vulnerability disclosure policies to improve trust and legal clarity.

Technical notes

Notes

The website is built on WordPress CMS version 6.8.3, using modern JavaScript libraries such as Leaflet.js for interactive maps and Flickity for carousel functionality. It integrates Google Analytics and Google Tag Manager for user behavior tracking and performance monitoring. The site uses a cookie consent management platform (CookieScript) to comply with privacy regulations. The design is responsive and optimized for mobile devices, with good accessibility features. Performance is moderate, with external resources loaded from reputable CDNs. The site does not reveal hosting provider details explicitly. Technical risks include reliance on third-party scripts and lack of some security headers, which should be addressed to reduce attack surface.
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.
