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

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

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

ZUŠ Jihlava holds a strong position as a regional educational institution specializing in arts education. Its business model is primarily public and grant-funded education, supplemented by donations and community support. The school demonstrates active participation in national and international competitions, enhancing its reputation and appeal. The website's extensive content and event documentation indicate a vibrant community and strong stakeholder engagement. The lack of explicit privacy and cookie policies suggests an area for compliance improvement. The domain age and WHOIS data confirm legitimacy and consistency with the school's identity. The school maintains partnerships with local cultural and educational organizations, as evidenced by linked domains and event collaborations.

Security posture

The website employs HTTPS, ensuring encrypted communication, which is a fundamental security measure. However, the use of an outdated jQuery version (1.7) introduces potential vulnerabilities that could be exploited. The absence of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the site's defense against common web attacks like clickjacking and cross-site scripting. No incident response or security policy information is publicly available, indicating limited transparency in security governance. No forms or input fields were detected that might require additional security controls. Overall, the security posture is moderate but could benefit significantly from updates and enhanced security practices.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against web attacks.
  4. Conduct regular security audits and vulnerability assessments of the Drupal installation and modules.
  5. Enhance transparency by publishing security policies and incident response procedures on the website.

Technical notes

Notes

The website is built on Drupal 7, a mature but aging CMS platform, using modules like Views Slideshow and Colorbox for enhanced UI features. The JavaScript stack includes jQuery 1.7, which is outdated and may pose security risks. The site loads multiple CSS and JS assets from its own domain, indicating self-hosted resources. Mobile optimization is good with responsive menus and media queries. SEO is basic with meta tags and Open Graph properties but lacks advanced structured data like JSON-LD. Performance is moderate, with potential improvements by updating libraries and optimizing assets. Accessibility is basic, with no explicit ARIA roles or landmarks detected. Hosting is via REG-INTERNET-CZ registrar with DNS servers ns.forpsi.net and ns.forpsi.it, consistent with Czech hosting providers.
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.
