Risk levelMedium

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

The website www.dub.cz represents the Duchovní universita Bytí, an organization focused on spiritual philosophy and the teachings of Josef Zezulka, particularly in the field of Biotronika and alternative medicine. It serves a niche audience interested in spiritual education, events, and community engagement primarily in the Czech Republic but with multilingual support for international visitors. The site offers lectures, concerts, video content, and publications, positioning itself as a small but dedicated non-profit educational entity. Technically, the website employs a moderate technology stack including jQuery, bxSlider, Google Tag Manager, and reCAPTCHA, ensuring basic interactivity and security. The site is mobile optimized and provides a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS and reCAPTCHA usage, but lacks some security headers and explicit privacy policies, which are areas for improvement. The absence of WHOIS data reduces transparency and trust slightly, but the active and professional nature of the site, along with partner references, supports its legitimacy. Overall, the site is functional, moderately secure, and serves its community well, though it would benefit from enhanced privacy and security disclosures.

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.

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

The organization behind www.dub.cz operates in the spiritual and alternative medicine sector, focusing on education and community events. Its business model is non-commercial, relying on donations, events, and publication sales. The website links to several partner organizations and foundations, indicating a collaborative ecosystem. The target audience includes individuals interested in spiritual growth, alternative healing, and philosophical teachings. The site’s multilingual support suggests an intent to reach an international audience. Growth indicators include active event promotion and multimedia content. Competitive advantages lie in its niche focus and established community presence. The lack of explicit business registration details and WHOIS transparency is a minor concern but does not detract significantly from its community credibility.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and Google reCAPTCHA is implemented on forms to prevent automated abuse. However, the absence of common security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. No direct contact information for security incidents or abuse is provided, which limits incident response readiness. Privacy compliance is partial, with a cookie consent banner present but no detailed privacy policy or GDPR compliance statements. No vulnerabilities or exposed sensitive data were detected in the content. The security posture is adequate for a small non-profit site but should be enhanced to meet higher standards and regulatory requirements.

Recommendations

  1. Implement a comprehensive privacy policy page detailing data collection, processing, and GDPR compliance.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy) to improve security posture.
  3. Provide clear contact information for security incidents and abuse reporting to enhance incident response capabilities.
  4. Regularly update all JavaScript libraries and dependencies to their latest secure versions.
  5. Enhance transparency by publishing WHOIS data or ensuring domain registration information is publicly available.

Technical notes

Notes

The website uses a traditional web stack with jQuery and bxSlider for UI components, Google Fonts for typography, and Google Tag Manager for analytics and marketing tags. The presence of Google reCAPTCHA indicates attention to form security. The site is mobile responsive with CSS media queries and offers multilingual support via hreflang tags. Performance is moderate, with some external dependencies on CDNs and Google services. No CMS was detected, suggesting a custom or static site architecture. Accessibility is basic, with room for improvement in semantic markup and ARIA attributes. SEO is supported by meta tags and Open Graph images but could be enhanced with structured data. Overall, the technical implementation is solid for a small educational site but could benefit from modernization and improved security practices.
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.
