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

Vzdělávací centrum Planeta Hlinsko, p.o. is a local educational and cultural institution in the Czech Republic focused on providing engaging educational experiences about Earth sciences and natural phenomena. The website serves as an official portal offering information about their exhibitions, lectures, programs for schools and seniors, and event calendars. It targets a broad audience including families, students, and seniors, positioning itself as a community educational center. Technically, the website is built on a CMS platform by Galileo Corporation, utilizing modern JavaScript libraries such as jQuery, Bootstrap, and Leaflet for maps. The site is mobile-optimized, accessible, and provides a good user experience with clear navigation and relevant content. Security posture is solid with HTTPS and cookie consent implemented, though it lacks some security headers and formal privacy and terms policies. WHOIS data is unavailable, which slightly impacts trust but the site content and contact details appear legitimate and consistent with a public institution. Overall, the site is professional and trustworthy but could improve compliance and security transparency.

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

7 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 institution operates as a non-profit educational center providing science and cultural education primarily to the local community and schools. Its business model revolves around educational programs, exhibitions, and events, including summer camps and workshops. The website integrates with external ticketing services and maintains social media presence on Facebook and Instagram to engage its audience. The partnership with Galileo Corporation indicates reliance on specialized CMS and web services. The organization appears stable with clear contact information and operational hours, but lacks publicly visible privacy and security policies which are important for compliance and trust. Growth opportunities could include enhanced digital engagement and formalizing data protection practices.

Security posture

The website enforces HTTPS and includes a cookie consent mechanism, indicating awareness of basic security and privacy requirements. However, it lacks visible security headers such as Content-Security-Policy, X-Frame-Options, and others that enhance protection against common web attacks. No incident response or vulnerability disclosure information is provided, which limits transparency and preparedness. The absence of WHOIS data reduces domain trust slightly but does not indicate malicious intent. No vulnerable or outdated libraries were detected in the scripts included. Overall, the security posture is moderate with room for improvement in headers, policies, and incident readiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  2. Implement security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection.
  3. Add a security.txt file to provide vulnerability disclosure and incident response contact information.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by providing data protection officer contact details and GDPR compliance statements.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Bootstrap 4, Swiper.js for sliders, PhotoSwipe for image galleries, Mmenu for mobile menus, and Leaflet.js for map integration. It is built on a CMS platform by Galileo Corporation, which is specialized for municipal and educational websites. The site is mobile responsive and includes accessibility features such as skip links and ARIA labels. Performance is moderate with multiple external scripts but no obvious bottlenecks. SEO is supported by proper meta tags and structured navigation. Technical risks include missing security headers and lack of formal privacy and security documentation. The site is well-structured and professionally maintained but could benefit from enhanced security and compliance features.
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.
