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

Městské kulturní středisko Třebíč operates as a local government cultural center providing comprehensive information on cultural events such as cinema, theater, concerts, and exhibitions in Třebíč, Czech Republic. The website serves residents and visitors by offering event listings, ticket sales, and venue rental information, positioning itself as a key cultural hub in the region. The business model is public-sector focused, emphasizing community engagement and cultural promotion. Technically, the website employs a modern JavaScript stack including jQuery, Modernizr, Swiper.js, and Fancybox, alongside Google Analytics and Tag Manager for analytics and marketing. The site is mobile-optimized with good SEO practices and a cookie consent mechanism compliant with GDPR. Hosting details are not explicit, but the site is professionally designed and performs moderately well. From a security perspective, HTTPS is enforced, and cookie consent is implemented, but security headers are not explicitly detected, and no security.txt or incident response policies are published. No vulnerabilities or exposed sensitive data were found in the HTML content. Privacy compliance is good with a clear privacy policy and cookie management. Overall, the website is trustworthy and professional, though the absence of WHOIS data due to privacy protection slightly reduces transparency. The site is safe for general audiences and does not contain adult or explicit content. Strategic improvements include enhancing security headers, publishing security policies, and providing clearer contact information to strengthen trust and compliance.

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

6 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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 is a government cultural center focused on promoting and managing cultural activities in Třebíč. It leverages digital channels to engage local and visiting audiences interested in arts and entertainment. The website acts as a centralized platform for event discovery and ticketing, supporting local cultural infrastructure. Partnerships with local tourism and municipal websites indicate a collaborative ecosystem. The business model is service-oriented, funded likely by public budgets, with no evident commercial sales beyond ticketing. Growth indicators include active event promotion and marketing campaigns. The company maintains a consistent brand and digital presence, reinforcing its role as a cultural authority in the region.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent mechanisms in place. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security or incident response policies indicate room for improvement. No vulnerabilities or sensitive data exposures were detected in the analyzed content. The site uses third-party analytics and advertising services, which are disclosed via cookie policies. Incident response readiness and vulnerability disclosure mechanisms are not evident, which could impact rapid mitigation of security incidents. Overall, the security posture is adequate for a public cultural website but should be enhanced to align with best practices and compliance requirements.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate vulnerability reporting and responsible disclosure.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Provide clear and verified contact information including official emails and phone numbers to strengthen business credibility.

Overall, the technical infrastructure supports a professional and functional user experience.
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.
