JOJ.sk is the official website of a major Slovak television broadcaster offering live streaming, TV program schedules, episodes, and exclusive video content. The site targets a general audience interested in Slovak media content. Technically, the website employs modern web technologies including Google Tag Manager, Facebook Pixel, Prebid.js for advertising, and a consent management platform (DIDOMI) to comply with GDPR. The site is well-optimized for mobile and SEO, with good performance and user experience. Security posture is solid with HTTPS and some security headers, though additional headers could enhance protection. Privacy compliance is supported by a consent mechanism, but explicit privacy and terms of service pages were not found in the provided content. Overall, the domain registration data aligns well with the business profile, indicating legitimacy and transparency.

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

      Detected services: Google Analytics, Facebook, Twitter, YouTube, Cloudflare

      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

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

JOJ operates in the media sector as a large Slovak TV broadcaster with a strong online presence. Its business model revolves around content broadcasting and monetization through advertising, leveraging multiple ad networks and advanced header bidding technologies. The target market is Slovak-speaking general audiences. The company uses multiple analytics and marketing tools to optimize user engagement and ad revenue. The absence of direct contact or detailed corporate information on the site suggests a focus on content delivery rather than direct customer interaction online. The partnership ecosystem includes advertising and analytics providers, with no suspicious or unrelated domains detected.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, GDPR-compliant consent management, and no visible exposure of sensitive data. However, security headers are minimal, and no explicit security or incident response policies are published. The use of multiple third-party scripts and ad networks introduces potential risk vectors, but no vulnerable libraries or critical issues were detected in the analyzed content. The site would benefit from publishing a vulnerability disclosure policy and enhancing HTTP security headers to improve defense in depth.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear privacy policy and terms of service accessible from the homepage.
  3. Add a vulnerability disclosure or security.txt file to facilitate responsible security reporting.
  4. Provide visible contact information for security incidents or general inquiries.
  5. Regularly audit third-party scripts and ad networks for security and privacy compliance.

Technical notes

Notes

The website uses a modern tech stack with asynchronous loading of scripts to optimize performance. It integrates multiple advertising technologies including Prebid.js for header bidding and several ad networks. Consent management is handled by DIDOMI CMP, ensuring GDPR compliance. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. Hosting and CMS details are not explicitly identified but the infrastructure supports video streaming and interactive content. Performance is moderate, with room for improvement in accessibility and security headers. The technical implementation supports a professional media content delivery platform.
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.
