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

Základní umělecká škola Jeseník is a well-established educational institution in the Czech Republic, providing artistic education in music, literature, drama, and visual arts since 1948. The website serves as a portal for students, parents, and the community to access information about courses, cultural events, and school news. The institution maintains a regional presence with a focus on family and youth engagement through specialized courses and orchestras. Technically, the website is built on the Noteo Engine CMS, uses modern web technologies such as HTML5, CSS, JavaScript, and FontAwesome icons, and is served over HTTPS ensuring secure communication. However, the absence of explicit security headers and privacy policy pages indicates room for improvement in security and compliance. The site includes a cookie consent mechanism that denies ad and analytics storage by default, reflecting a privacy-conscious approach. Contact information is clearly presented, enhancing business credibility. Overall, the website is functional, informative, and trustworthy for its target audience.

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

11 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

      Missing X-Frame-Options header

      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 entity focused on arts education, targeting families, children, and young adults in the Jeseník region. Its business model revolves around providing structured artistic education and organizing cultural events, which likely generate community engagement and public funding. The website highlights partnerships with local orchestras and cultural groups, indicating a collaborative ecosystem. The institution's long history and active event calendar position it as a key cultural player in the region. Revenue streams are presumably from public funding, tuition fees, and donations, as indicated by the financial aid request section. The presence of social media channels supports outreach and community building. Strategic observations suggest the school could enhance digital presence by improving privacy and security compliance and expanding online services.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, ensuring encrypted data transmission. The login form for user authentication is present but lacks visible advanced security features such as multi-factor authentication. Security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, which could expose the site to clickjacking, MIME sniffing, and cross-site scripting risks. The cookie consent mechanism is implemented with default denial of ad and analytics storage, aligning with privacy best practices. No vulnerabilities or malware indicators were found in the provided data. The absence of WHOIS information reduces trust signals but does not directly impact site security. Recommendations include implementing missing security headers, regular library updates, and publishing a privacy policy to enhance compliance and user trust.

Recommendations

  1. Implement a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  3. Regularly audit and update JavaScript libraries and dependencies to mitigate vulnerabilities.
  4. Enhance login security by considering multi-factor authentication and secure password policies.
  5. Publish terms of service and incident response contact information to improve transparency and preparedness.

Technical notes

Notes

The website is built on the Noteo Engine CMS platform, utilizing standard web technologies including HTML5, CSS, JavaScript, and jQuery. FontAwesome is used for iconography, and Adobe Typekit fonts are loaded for typography. The site loads asynchronously scripts for form validation and cookie management. Performance is moderate with some optimization opportunities in caching and script loading. Mobile optimization is good, with responsive design elements and viewport meta tags. Accessibility features are basic, with room for improvement in ARIA roles and keyboard navigation. SEO optimization is basic, with meta tags present but lacking detailed descriptions and keywords. Hosting provider details are not disclosed. Overall, the technical infrastructure supports the business needs 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.
