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

Téčko is a cultural organization based in Rožnov pod Radhoštěm, Czech Republic, providing a wide range of cultural events including concerts, exhibitions, workshops, and cinema programs. The organization targets local citizens and visitors interested in cultural and educational activities. The website presents a professional and well-structured platform with event calendars, ticket sales, and multimedia galleries, supporting its role as a community cultural hub. Technically, the site uses established JavaScript libraries and cookie consent tools, with HTTPS enabled ensuring secure communication. However, the absence of WHOIS data raises concerns about domain registration legitimacy, though the website content and social media presence suggest a legitimate entity. Privacy compliance is well addressed with GDPR-aligned policies and cookie consent mechanisms. Security posture is moderate, with room for improvement in security headers and incident response transparency. Overall, the site is functional, user-friendly, and trustworthy from a content perspective but would benefit from enhanced security practices and domain registration clarity.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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 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';…

  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 organization operates as a non-profit cultural entity, focusing on delivering cultural and educational programs to the local community. Its business model revolves around event organization, ticket sales, and educational workshops, targeting schools and the general public. Téčko maintains partnerships, notably with Klub Vrátnice, enhancing its event offerings. The website's content quality and social media integration indicate a medium-sized organization with a stable market position in the local cultural sector. The lack of explicit company registration or contact details on the website limits deeper business intelligence insights. The organization appears to prioritize community engagement and cultural enrichment over commercial activities.

Security posture

The website enforces HTTPS and implements cookie consent aligned with GDPR, reflecting a baseline security and privacy awareness. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates potential vulnerabilities to common web attacks. No incident response or vulnerability disclosure information is provided, limiting transparency and preparedness for security incidents. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The security score is moderate, with recommendations to enhance header implementation and provide clear security contact channels to improve resilience and trust.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web vulnerabilities.
  2. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Provide explicit incident response contact information to improve transparency and readiness.
  4. Verify and update WHOIS domain registration information to ensure legitimacy and trustworthiness.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and security posture.

Technical notes

Notes

The website uses a traditional jQuery-based tech stack with plugins for UI components such as carousels and modal dialogs. Cookie consent is managed via a third-party script from FreePrivacyPolicy.com. The site is mobile responsive with a clear navigation structure and SEO-friendly meta tags including Open Graph metadata. Performance is moderate, with no major blocking scripts detected. No modern frameworks (React, Angular, Vue) or CMS platforms were identified, suggesting a custom or legacy build. Hosting provider details are not discernible from the HTML content. The site could benefit from modernization to improve maintainability and performance.
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.
