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

    • 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 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

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 institution holds a unique market position as a regional provider of artistic education in Ostrava, supported by the city government. Its business model is that of a public organization funded by municipal resources, focusing on cultural and aesthetic education for a broad demographic. The website supports this with detailed program offerings, event announcements, and multiple physical locations. The presence of social media channels and Google Analytics indicates engagement with modern marketing and analytics tools. There is no evidence of commercial revenue streams or partnerships beyond city affiliation. Growth indicators include new facility openings and active event programming.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is properly implemented, and cookie consent mechanisms comply with basic privacy requirements. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No vulnerability disclosures or incident response contacts are published, which limits transparency in security management. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate for a public educational site but could be improved with formal policies and enhanced header configurations.

Recommendations

  1. Implement and publish a comprehensive privacy policy detailing GDPR compliance.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  3. Publish a security policy and incident response contact information to improve transparency.
  4. Clarify WHOIS registration details or ensure domain registration data is publicly available.
  5. Regularly review and update cookie consent and analytics practices to maintain privacy compliance.

Technical notes

Notes

The website uses a custom or unknown CMS with modern front-end technologies including minified CSS and JavaScript assets, SVG icons, and asynchronous loading of Google Tag Manager scripts. Performance is moderate with good mobile responsiveness and accessibility features such as skip links and ARIA attributes. SEO is supported by proper meta tags and structured navigation. Hosting provider details are not discernible from the content. There is no evidence of legacy or vulnerable libraries. The site could benefit from enhanced technical SEO and security header implementation to reduce technical risks.
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.
