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

Centrum experimentálního divadla, p.o. is a public cultural institution based in Brno, Czech Republic, dedicated to fostering professional and experimental live theater arts. It operates several theaters including Divadlo Husa na provázku, HaDivadlo, and Terén, and publishes a quarterly magazine called CEDIT. The institution is supported financially by the city of Brno and the Ministry of Culture of the Czech Republic, positioning it as a key player in the regional cultural landscape. The website reflects this mission with rich content about performances, projects, and educational activities targeting a general audience interested in experimental theater and culture. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript with jQuery, and Mapbox GL JS for interactive maps. It features a responsive design with good mobile optimization and basic accessibility features. The site includes a cookie consent mechanism and uses Google Analytics for traffic analysis, indicating moderate digital maturity. However, the absence of a privacy policy and terms of service pages represents a compliance gap. From a security perspective, the site uses HTTPS and implements cookie consent but lacks visible security headers and does not provide incident response or vulnerability disclosure information. The WHOIS data for the domain is unavailable, which limits the ability to verify domain legitimacy and age, slightly reducing trustworthiness. Nonetheless, the presence of official city support logos and consistent branding enhances credibility. Overall, the website is professionally designed and functional, serving its cultural mission effectively. Strategic improvements in privacy compliance, security headers, and domain registration transparency would enhance trust and security posture, supporting long-term institutional credibility and user confidence.

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

11 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

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 public cultural entity in Brno, leveraging partnerships with established theaters and government bodies. Its business model centers on cultural event production, theater performances, educational initiatives, and publishing. Revenue streams likely include public funding and ticket sales. The target audience includes theater enthusiasts, cultural consumers, and the local community. The partnership ecosystem includes theaters under its umbrella and governmental cultural agencies, reinforcing its legitimacy and operational capacity. Growth indicators include active programming and a quarterly magazine launch. Strategic observations suggest focusing on digital compliance and security to maintain public trust and expand outreach.

Security posture

The current security maturity is moderate. HTTPS is enforced, and cookie consent is implemented, reflecting basic privacy awareness. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response contacts are provided, limiting transparency and readiness. The absence of WHOIS data complicates domain legitimacy verification. Compliance gaps include missing privacy and terms of service documents, which are critical under GDPR. The institution should prioritize publishing these policies, enhancing header security, and establishing clear incident response channels to improve security culture and regulatory compliance.

Recommendations

  1. Publish comprehensive privacy policy and terms of service pages to address compliance gaps.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen security posture.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file for transparency.
  4. Verify and update WHOIS domain registration information to improve trustworthiness.
  5. Conduct regular security audits of third-party libraries and scripts to mitigate vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, JavaScript, jQuery 3.5.1, and Mapbox GL JS for mapping features. It loads asynchronously and defers scripts to optimize performance. The design is responsive and mobile-friendly with good navigation clarity. SEO is basic with meta description and viewport tags but lacks Open Graph or JSON-LD structured data. No CMS is detected, suggesting a custom or static site. Hosting provider details are not available. Performance is moderate, with some room for optimization. Accessibility is basic, with no explicit ARIA roles or landmarks detected. Overall, the technical implementation supports the business goals but could benefit from enhanced SEO and accessibility improvements.
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.
