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

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 strong market position as a leading theatre organization in Prague, supported by partnerships with governmental and cultural bodies such as the Ministry of Culture and the City of Prague. Its business model revolves around cultural event production, ticketing, and educational outreach, with revenue streams likely from ticket sales, sponsorships, and grants. The website integrates e-commerce capabilities for ticket purchases and maintains active engagement through social media and media content. The partnership ecosystem includes recognized cultural and governmental entities, enhancing credibility and reach. Growth indicators include active programming, educational initiatives, and digital content expansion. The organization's operations reflect a well-established cultural institution with a clear focus on audience engagement and service delivery.

Security posture

The website exhibits a mature security posture with HTTPS enabled and secure handling of user inputs via POST forms. Tracking and marketing scripts are implemented with user consent mechanisms, reflecting privacy awareness. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not detected, representing an area for enhancement. No vulnerabilities or exposed sensitive data were identified in the HTML content. The absence of a published security policy or incident response contact limits transparency in security governance. The lack of a vulnerability disclosure program or security.txt file suggests opportunities to improve security communication and incident handling readiness. Overall, the security maturity is good but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and trust.
  3. Establish a vulnerability disclosure program and consider adding a security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party libraries and tracking scripts to mitigate potential vulnerabilities.
  5. Enhance data retention and privacy documentation to align with evolving GDPR and NIS2 compliance requirements.

Technical notes

Notes

The website is built on a CMS platform (cms3.nux.cz) and utilizes a modern tech stack including Bootstrap for responsive design, jQuery for DOM manipulation, and specialized libraries for galleries and sliders. Analytics and marketing integrations include Matomo, Google Tag Manager, Facebook Pixel, and Adform, all implemented with asynchronous loading to optimize performance. The site demonstrates good mobile optimization and accessibility features, with semantic HTML and ARIA attributes. Performance is moderate, with potential improvements in resource loading and caching. The technical infrastructure supports a professional and engaging user experience, though opportunities exist to enhance security headers and streamline third-party dependencies for improved security and speed.
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.
