OneTV.cz is a Czech internet television platform operated by BurdaMedia Extra s.r.o., offering entertaining and viral video content to a broad audience. The website is well-positioned in the Czech media market, targeting general viewers with information and entertainment shows. The platform leverages WordPress CMS with custom video player integrations and employs modern web technologies including Google Tag Manager, Google Analytics, and Facebook Pixel, all gated by a consent management platform to ensure GDPR compliance. The site demonstrates good technical maturity with mobile optimization and SEO best practices. Security posture is solid with HTTPS enforcement and content security policies, though additional security headers could enhance protection.

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

9 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. 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

OneTV.cz operates as an online media content platform focusing on viral and entertaining video content, monetized primarily through advertising networks such as Performax and retargeting via Facebook Pixel. The business benefits from its association with BurdaMedia Extra s.r.o., a recognized media company, which strengthens its market position. The platform targets a general audience in the Czech Republic, with content designed to engage viewers daily. The website's integration with multiple marketing and analytics tools indicates a data-driven approach to audience engagement and advertising effectiveness. The lack of direct contact information on the homepage suggests a focus on content delivery rather than direct customer service. Strategic partnerships with Burda domains and advertising networks support its operational ecosystem.

Security posture

The website exhibits a mature security posture with HTTPS enabled and a Content Security Policy that upgrades insecure requests. The use of a consent management platform (Didomi) ensures compliance with GDPR and user privacy preferences. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the site could improve by adding additional security headers such as X-Frame-Options and X-Content-Type-Options to mitigate clickjacking and MIME sniffing risks. The absence of a security.txt file or explicit incident response contact information limits transparency for vulnerability reporting. Overall, the security measures are appropriate for a media content platform but could be enhanced to align with best practices.

Recommendations

  1. Implement additional HTTP security headers including X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  2. Publish a security.txt file to facilitate vulnerability disclosure and improve incident response transparency.
  3. Enhance accessibility features to improve compliance and user experience for all users.
  4. Provide clear and accessible contact information for business and security inquiries.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website is built on WordPress CMS with a custom theme and uses jQuery 1.9.1, which is an older version and may pose security risks if not updated. It integrates multiple third-party scripts for analytics, advertising, and consent management, including Google Tag Manager, Google Analytics, Facebook Pixel, Didomi CMP, and CPEX CMP. The site uses a custom video player script (BurdaVideoPlayer) for content delivery. Performance is moderate with asynchronous loading of scripts and mobile optimization evident. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data. Accessibility is basic with some navigation aids but could be improved. The hosting provider is not explicitly identified. Overall, the technical infrastructure is modern but could benefit from updating legacy libraries and enhancing 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.
