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

Divadlo Kalich is a cultural venue based in Prague, Czech Republic, offering a variety of theatrical performances including comedies, musicals, concerts, and children's shows. The website serves as a platform for event listings and ticket sales, targeting a broad audience interested in live theater and cultural events. The site demonstrates a moderate level of digital maturity with the use of modern tracking technologies such as Google Analytics, Facebook Pixel, and Cookiebot for consent management. The technical infrastructure supports HTTPS and responsive design, ensuring accessibility and a good user experience across devices. However, the absence of publicly available WHOIS data limits the ability to fully verify domain legitimacy and registrant information. Security posture is adequate with HTTPS and cookie consent, but could be improved by implementing security headers and publishing clear privacy and security policies. Overall, the website is functional and professional but would benefit from enhanced transparency and security documentation.

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

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

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Divadlo Kalich operates in the hospitality sector, specifically within the cultural and entertainment industry. Its business model revolves around hosting and promoting live theatrical performances and concerts, generating revenue primarily through ticket sales. The venue maintains multiple stages and collaborates with various performers and production teams. The website's event calendar and ticketing system indicate a well-organized operation targeting local and regional audiences. The use of analytics and marketing tools suggests an active approach to audience engagement and promotion. While the site lacks explicit business registration details, the consistent branding and event information support its position as an established cultural institution in Prague.

Security posture

The website employs HTTPS, ensuring encrypted communication between users and the server. Cookie consent is managed via Cookiebot, indicating awareness of privacy regulations such as GDPR. Tracking scripts from Google and Facebook are present, which may raise privacy considerations if not fully disclosed. No security headers were detected in the provided data, representing an area for improvement to mitigate common web vulnerabilities. The absence of a published privacy policy, terms of service, or security incident response information limits transparency and user trust. No vulnerabilities or exposed sensitive data were identified in the analysis. Overall, the security posture is moderate but could be strengthened by adopting best practices in security headers, policy disclosures, and incident response readiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to enhance transparency and compliance.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve security posture.
  3. Provide clear contact information including security or abuse email addresses to support incident reporting and response.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly review and update cookie consent and tracking disclosures to ensure GDPR compliance and user trust.

Technical notes

Notes

The website utilizes a combination of modern web technologies including Google Tag Manager, Google Analytics, Facebook Pixel, and Cookiebot for analytics and consent management. The presence of Owl Carousel indicates use of jQuery-based UI components for interactive content display. The site is served over HTTPS, ensuring secure data transmission. Meta tags and viewport settings support SEO and mobile responsiveness. However, no CMS or hosting provider information was identified. Performance appears moderate with asynchronous loading of scripts. Accessibility features are basic, with room for improvement in semantic markup and ARIA attributes. The technical stack is adequate for the site's purpose but could benefit from modernization and enhanced security configurations.
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.
