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.

Priority findings

7 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

      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

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 theatre holds a strong market position as a key cultural institution in Prague, targeting theatre enthusiasts and the general public interested in arts and culture. Its business model is primarily public funding supplemented by ticket sales, subscriptions, and venue rentals. The organization benefits from partnerships with the City of Prague and maintains active engagement through social media and newsletters. Growth indicators include active event programming and educational offerings. The theatre's digital ecosystem is modern and well-maintained, supporting its operational and marketing needs effectively.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Cookie consent is implemented in compliance with GDPR. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident and should be added to enhance protection against common web attacks. No incident response or security policy pages are found, which could improve transparency and preparedness. The use of third-party scripts like Google Tag Manager is standard but requires ongoing monitoring for vulnerabilities. Overall, the security measures are adequate for the business type but could be improved with additional best practices.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.
  4. Enhance user trust by providing more detailed business and compliance information on the website.
  5. Maintain and monitor GDPR compliance with periodic reviews and updates to privacy and cookie policies.

Technical notes

Notes

The website is built on a modern React and Next.js framework, hosted on Google Cloud, which supports scalability and performance. The use of Firebase Storage for media assets indicates a cloud-native approach. The site is mobile-optimized with responsive design and good accessibility features. SEO is well addressed with proper meta tags and Open Graph data. Performance is fast with asynchronous script loading. There is no indication of legacy or vulnerable libraries. Opportunities exist to improve security headers and add structured data for enhanced SEO and accessibility.
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.
