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

The website zsvelhartice.cz represents the official portal of Základní škola a mateřská škola Velhartice, a small educational institution in the Czech Republic founded in 2008. The site provides important information about school events, documents, forms, and contacts primarily targeting parents and the local community. The business model is that of a public educational institution serving primary and kindergarten education needs. Technically, the website uses standard web technologies including HTML5, CSS3, JavaScript, and FontAwesome icons. It is hosted with Cloudflare DNS services, ensuring reliable domain resolution and basic security. The site is moderately optimized for performance and mobile devices, with basic accessibility and SEO features. From a security perspective, the site employs HTTPS and Cloudflare DNS but lacks advanced security headers such as Content-Security-Policy and HSTS. There are no visible vulnerabilities or exposed sensitive data. However, the absence of privacy and cookie policies indicates a compliance gap with GDPR requirements. Overall, the website is professional and trustworthy for its educational purpose, but improvements in privacy compliance and security headers are recommended to enhance user trust and regulatory adherence.

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.

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

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

Základní škola a mateřská škola Velhartice operates as a local public school providing primary and kindergarten education services. Its market position is focused on serving the local community in the Czech Republic. The website content and metadata indicate a clear target audience of parents and local residents seeking school-related information. The business model is non-commercial, funded likely by public sources. There is no indication of subsidiaries or parent companies. The site maintains consistent branding and provides trust signals such as official domain registration and contact forms. The partnership ecosystem is minimal, with external links primarily to Cloudflare and FontAwesome resources.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, and DNS is managed via Cloudflare, providing foundational security benefits. However, the site lacks several recommended security headers that could mitigate risks such as clickjacking, MIME sniffing, and cross-site scripting. No incident response contacts or vulnerability disclosure policies are present, which limits transparency in security management. The absence of privacy and cookie policies also represents a compliance risk under GDPR. No third-party tracking or advertising scripts were detected, reducing privacy concerns. Overall, the security posture is adequate for a small educational site but could be improved with enhanced headers and compliance documentation.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Establish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Include explicit contact information such as official emails and phone numbers for better user trust and communication.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using standard web technologies with a custom or unknown CMS. It uses FontAwesome for icons and Cloudflare for DNS management. The site is responsive and moderately optimized for mobile devices. Performance is average with no major issues detected. SEO is basic with meta tags for keywords and description present. Accessibility features are minimal but present. There is no evidence of advanced frameworks or platforms. The site could benefit from modernizing its tech stack and improving accessibility and SEO 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.
