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

Základní umělecká škola Rosice is a small educational institution based in the Czech Republic, providing foundational arts education in music, visual arts, and dance primarily to children and young people in the local community. The school is operated under the Jihomoravský kraj regional authority and offers various programs including student concerts, exhibitions, and competitions. The website reflects a well-structured and professionally designed platform that supports enrollment and provides information about the school's offerings and events. Technically, the site uses common web technologies such as jQuery, Bootstrap, and FontAwesome, with integration of Google Analytics for visitor tracking. Security-wise, the site implements cookie consent mechanisms but lacks visible security headers and detailed privacy or security policies. WHOIS data is unavailable, which limits domain trust assessment, but the website content and contact details appear legitimate and consistent with a local educational institution. Overall, the site is safe, accessible, and provides a good user experience, though improvements in security posture and privacy transparency are recommended.

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

9 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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"

      • 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 occupies a niche in the regional education sector, focusing on arts education for youth. Its business model is non-commercial, likely funded by regional government resources, with a focus on community engagement and cultural development. The website supports this mission by providing clear information on enrollment, programs, and events. The presence of social media and external links to regional government sites indicates an integrated partnership ecosystem. Growth indicators are limited but the site shows active event updates and engagement. The lack of WHOIS data is a minor concern but does not detract significantly from the institution's credibility given its public sector nature.

Security posture

The website demonstrates a basic security posture with HTTPS implied but no explicit security headers detected in the provided data. Cookie consent is implemented with granular user controls, indicating awareness of privacy regulations. However, the absence of a privacy policy page, security policy, and incident response contacts suggests gaps in compliance and readiness. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party scripts like Google Analytics and FontAwesome is standard but should be regularly audited. Overall, the security maturity is moderate with room for improvement in policy transparency and technical safeguards.

Recommendations

  1. Implement and publish a comprehensive privacy policy page to enhance GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve security posture.
  3. Ensure HTTPS is enforced site-wide with strong SSL/TLS configuration and regularly monitor for vulnerabilities in third-party scripts.
  4. Provide clear incident response contact information and consider establishing a security policy page.
  5. Regularly review and update cookie consent mechanisms and data retention policies to align with evolving privacy regulations.

Technical notes

Notes

The website is built on a standard stack including jQuery 3.5.1, Bootstrap, Owl Carousel, Lightbox, and FontAwesome, which are widely used and supported. Google Tag Manager is used for analytics, indicating a moderate level of digital maturity. The site is mobile responsive and has good navigation clarity. Performance is moderate, with no major issues detected in the HTML content. There is no evidence of a CMS or hosting provider from the data. Accessibility features are basic but present. SEO optimization is basic with meta tags and Open Graph tags included but no structured data (JSON-LD) detected. Technical risks include the lack of security headers and missing WHOIS data which could impact trust and security assessments.
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.
