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

ZŠ Bratrství, příspěvková organizace, is a regional primary school located in the Czech Republic, focusing on fostering creativity, logical thinking, and mutual understanding among students. The website serves as an information portal for students, parents, and the local community, providing updates on school events, educational programs, and community projects. The school positions itself as an inclusive educational institution serving the Podhostýnsko region. Technically, the website employs common web technologies such as jQuery, FontAwesome, and Google reCAPTCHA, with integrations for social media platforms like Facebook and YouTube. The site is mobile-optimized and includes a cookie consent mechanism, reflecting a basic level of privacy compliance. Security-wise, the site uses HTTPS and some best practices but lacks visible security headers and a published incident response policy. The absence of WHOIS data for the domain is a notable concern, reducing trustworthiness and suggesting the need for further verification of domain registration status. Overall, the website is professional, content-rich, and trustworthy from a user perspective but could improve in security transparency and domain legitimacy verification.

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

8 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

    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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      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

The school operates as a public educational institution with a clear focus on primary education and community engagement. Its business model is non-commercial, funded likely through public or municipal sources, serving students and families in the local region. The website highlights partnerships with local organizations and educational support centers, indicating a collaborative ecosystem. The presence of educational projects and Erasmus+ programs suggests active participation in broader educational initiatives. The site’s content and structure support effective communication with stakeholders, though no direct revenue streams or commercial activities are evident. The school maintains a moderate online presence with social media integration and partner logos, reinforcing its community ties and credibility.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and integration of Google reCAPTCHA to mitigate automated abuse. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security reduces its defense-in-depth. No vulnerability disclosure or incident response information is published, which limits transparency and preparedness for security incidents. The cookie consent mechanism aligns with GDPR requirements, but no explicit data protection officer contact or detailed security policies are available. The lack of WHOIS data for the domain is a significant trust concern, potentially indicating registration issues or privacy protection that is not justified for a public institution. Overall, the security posture is adequate for a public school website but could be enhanced with improved headers, transparency, and domain registration clarity.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting and improve transparency.
  3. Verify and update domain WHOIS information to ensure legitimacy and build trust with users and partners.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Consider publishing an incident response policy and contact information to demonstrate preparedness and accountability.

Technical notes

Notes

The website uses a combination of popular JavaScript libraries and plugins such as jQuery, BxSlider, Owl Carousel, and Fancybox for UI components and interactivity. FontAwesome provides iconography, and Google reCAPTCHA v3 is integrated for bot mitigation. The site loads asynchronously scripts from Facebook SDK and Google services, indicating reliance on third-party platforms for social media and security features. The site is mobile responsive with viewport meta tags and uses CSS stylesheets for layout and theming. No CMS is explicitly detected, suggesting a custom or static site architecture. Performance is moderate, with potential improvements in loading optimization and modern framework adoption. The technical stack is stable but could benefit from modernization and enhanced security configurations.
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.
