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

Základní škola Jablůnka is a small primary educational institution located in the Czech Republic, serving approximately 200 students from grades 1 through 9. The school is municipally operated by the local government of Jablůnka and offers comprehensive educational services including daycare and a school canteen. The website reflects a well-maintained digital presence with regular updates on school activities and events, targeting students, parents, and the local community. Technically, the site employs common web technologies such as jQuery, Bootstrap, and Swiper.js, ensuring a responsive and user-friendly experience across devices. However, the site lacks advanced security headers and formal privacy and terms of service documentation, which are important for compliance and trust. The absence of WHOIS data limits domain legitimacy verification, but the presence of official contact details and local government affiliation supports the site's authenticity. Overall, the website demonstrates a good balance of content quality and technical implementation but would benefit from enhanced security and privacy compliance measures.

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 school operates as a public educational entity under the municipality of Jablůnka, focusing on providing quality primary education with a personal approach due to small class sizes. Its business model is non-commercial, funded by local government resources. The website serves as an information hub for students, parents, and staff, offering access to educational support, school news, and administrative documents. Partnerships with local institutions such as the municipality and nearby kindergartens strengthen its community integration. The site’s content and structure indicate a stable, community-focused operation with limited commercial ambitions but a strong emphasis on transparency and communication.

Security posture

The website benefits from HTTPS encryption and a cookie consent mechanism, indicating baseline security and privacy awareness. However, it lacks critical security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No vulnerability disclosure or incident response policies are publicly available, which could hinder timely security issue reporting. The absence of privacy and terms of service pages represents a compliance gap, especially under GDPR regulations. No analytics or tracking scripts were detected, reducing privacy risks but also limiting user behavior insights. Overall, the security posture is moderate but requires improvements to align with best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy policy and terms of service pages to enhance compliance and user trust.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen web security.
  3. Publish a security.txt file and establish a clear vulnerability disclosure process to improve incident response readiness.
  4. Regularly audit and update third-party libraries to prevent vulnerabilities from outdated components.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website uses a combination of established JavaScript libraries and frameworks such as jQuery, Bootstrap 4, Swiper.js, and jQuery.mmenu, providing a responsive and interactive user interface. The CMS appears to be a custom or EduPage-based system, common for educational institutions in the region. Performance is moderate with no major issues detected, though optimization opportunities exist. Mobile optimization is good, ensuring usability across devices. Accessibility is basic, with room for improvement to meet modern standards. SEO practices are present but could be enhanced with richer metadata and structured data. The lack of advanced security headers and absence of analytics tools suggest a conservative approach to tracking and security, which aligns with the institution's non-commercial nature but may limit insights and protection.
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.
