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

Základní umělecká škola Říčany is a Czech educational institution specializing in artistic education for children and youth, including music, dance, visual arts, and drama. The website serves as a communication platform for news, events, and projects related to the school and its community. It holds partnerships with cultural institutions such as the National Theatre and participates in EU-funded educational projects, indicating a stable position in the regional education sector. Technically, the website is built on a custom CMS developed by Vitalex Computers, utilizing a variety of JavaScript libraries including jQuery, Bootstrap, and TinyMCE. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. However, some technical improvements are recommended, such as adding security headers and enhancing accessibility. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms, reflecting awareness of privacy compliance. Nonetheless, the absence of WHOIS data and security headers, as well as missing explicit contact information for security incidents, represent areas for improvement. No vulnerabilities or malicious content were detected. Overall, the website is a trustworthy and professional platform for the school’s community, but it would benefit from enhanced transparency in domain registration and improved security practices to strengthen its credibility and compliance posture.

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

10 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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 · found on this site
  • 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 focused on arts education, targeting children, parents, and educators in the Říčany region of the Czech Republic. Its business model relies on government and EU funding, with strategic partnerships enhancing its cultural offerings. The website reflects a medium-sized institution with a consistent brand and a strong community presence. Growth indicators include active project participation and cultural collaborations. The lack of detailed business registration data online suggests a traditional public institution rather than a commercial enterprise. Competitive advantages include its comprehensive arts curriculum, community engagement, and EU project involvement. The school’s digital presence supports its educational mission but lacks advanced marketing or analytics tools, indicating a focus on service rather than commercial expansion.

Security posture

The website demonstrates a moderate security maturity level, with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense-in-depth posture. The use of older JavaScript libraries like jQuery 1.12.2 may expose the site to known vulnerabilities if not properly patched. No incident response or vulnerability disclosure information is provided, which limits transparency and preparedness for security events. The missing WHOIS data raises concerns about domain registration legitimacy, although the website content and EU funding references support its authenticity. Overall, the site is functional and secure for general use but requires enhancements to meet higher security standards and compliance expectations.

Recommendations

  1. Verify and update domain WHOIS registration to ensure transparency and trust.
  2. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options.
  3. Upgrade JavaScript libraries to latest secure versions to mitigate vulnerabilities.
  4. Publish explicit security policy and incident response contact information.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website uses a custom CMS platform developed by Vitalex Computers, leveraging common web technologies such as jQuery, Bootstrap, and TinyMCE for content management and UI components. The site is mobile responsive and includes interactive elements like sliders, audio players, and fancybox modals. Performance is moderate, with room for optimization in loading times and resource management. SEO is basic, with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility is at a basic level, lacking ARIA roles or enhanced keyboard navigation support. The absence of modern frameworks or platforms suggests a traditional web architecture that could benefit from modernization to improve scalability and maintainability.
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.
