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

Divadlo Oskara Nedbala Tábor is a well-established cultural institution in the Czech Republic offering a diverse range of theatrical, musical, and dance performances, as well as exhibitions and educational programs. It serves a broad audience with over 60,000 visitors annually, positioning itself as a key regional player in the cultural media sector. The website reflects a professional and consistent brand image with clear navigation and relevant content tailored to its audience. Technically, the site employs modern web technologies including Google Analytics, reCAPTCHA, and Google Maps API, ensuring a functional and moderately performant user experience with good mobile optimization. Security-wise, the site uses HTTPS and implements reCAPTCHA for form protection but lacks visible security headers and formal privacy and cookie policies, indicating areas for improvement in compliance and security posture. The absence of WHOIS data for the domain is a notable concern, impacting trust and legitimacy assessments. Overall, the website is safe, professional, and user-friendly but would benefit from enhanced transparency and security practices.

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

8 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"

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 organization operates primarily in the media and non-profit sectors, focusing on cultural event management and community engagement. Its business model revolves around ticket sales, subscriptions, and educational outreach, supported by partnerships with regional government and energy companies. The website's content and structure suggest a medium-sized entity with a stable market position in the Czech cultural landscape. The presence of multiple social media channels and partner logos indicates a well-integrated partnership ecosystem. However, the lack of detailed company registration or VAT information on the site limits deeper business verification. The institution's growth potential is supported by a diverse program offering and active audience engagement through newsletters and social media.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and use of Google reCAPTCHA to mitigate automated abuse on forms. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure policies are published, which could hinder timely handling of security issues. The lack of explicit privacy and cookie policies also indicates partial GDPR compliance gaps. No vulnerabilities or exposed sensitive data were detected in the HTML content. To enhance security posture, the organization should implement comprehensive security headers, formalize incident response procedures, and publish clear privacy and cookie policies.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against web attacks.
  3. Publish incident response and vulnerability disclosure policies to improve transparency and readiness.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Obtain and publish verified WHOIS domain registration information to strengthen trust and legitimacy.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics for tracking, Google reCAPTCHA for form security, and Google Maps API for location services. It loads fonts via Adobe Typekit and uses Popper.js and Font Awesome for UI components. The site is mobile-optimized with responsive design and includes structured navigation menus for desktop and mobile. Performance is moderate with asynchronous loading of scripts. However, no CMS or hosting provider information is discernible from the HTML. The site lacks some accessibility features and security headers, which are recommended for technical modernization and risk reduction.
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.
