The website is professionally designed with consistent branding and clear navigation, supporting a medium-sized media business founded in 2007. Technically, the site uses modern web technologies including Google Tag Manager and Google Analytics, with responsive design and lazy loading for performance optimization.

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. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

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

  2. Security headers

    • 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

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 company holds a strong regional position in the Czech and Slovak media market, operating multiple thematic TV channels and offering exclusive local film content. Its business model revolves around content broadcasting and digital streaming, targeting a broad audience of film fans. The presence of multiple subsidiary domains and partner sites indicates a diversified channel portfolio. The company benefits from professional web presence and partnerships, though lacks visible certifications or advanced security policies. Revenue streams likely include advertising and possibly subscription or licensing fees. Growth potential exists through digital expansion and enhanced user engagement.

Security posture

The website demonstrates a mature security posture with HTTPS and no visible sensitive data leaks. However, the absence of key security headers such as Content-Security-Policy and lack of published incident response or security policies represent gaps. No vulnerability disclosures or security.txt files were found, limiting transparency. The use of third-party analytics and tag management is standard but requires careful privacy management. Overall, the site is secure but could improve in formalizing security governance and enhancing user privacy controls.

Recommendations

  1. Implement a cookie consent banner to comply fully with GDPR and enhance user privacy transparency.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  3. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize data exposure.

Technical notes

Notes

The website uses a modern tech stack with asynchronous loading of Google Tag Manager and Analytics scripts, improving performance. Fonts are loaded from Google Fonts with preconnect hints, and images use lazy loading for efficiency. The site is responsive and mobile-optimized with good navigation clarity. No CMS or hosting provider was explicitly detected. Performance is moderate, with opportunities to improve accessibility features and SEO through enhanced metadata and ARIA attributes. The technical implementation supports a professional media platform but could benefit from additional security and privacy enhancements.
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.
