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

TVN24.pl is a leading Polish news portal operated by TVN S.A. and TVN Media Sp. z o.o., providing comprehensive national and international news coverage, live streaming, and multimedia content. The site targets Polish-speaking audiences interested in current affairs, business, health, technology, and regional news. The business model is primarily advertising-supported with premium subscription offerings under TVN24+. Technically, the website employs a modern tech stack including React-based components, OneTrust for cookie consent, Google Tag Manager, and advanced analytics platforms such as Gemius and Permutive. It uses service workers for performance and supports both desktop and mobile platforms with good accessibility and SEO practices. From a security perspective, the site enforces HTTPS, integrates GDPR-compliant consent mechanisms, and uses reputable third-party services for analytics and advertising. No critical vulnerabilities or exposed sensitive data were detected. However, enabling DNSSEC and additional security headers would enhance the security posture. Overall, TVN24.pl demonstrates a mature digital presence with strong business credibility, good privacy compliance, and a robust technical foundation. Strategic improvements in security headers and incident response visibility are recommended to maintain and enhance trust.

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

3 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 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

TVN24.pl holds a strong market position as a major Polish news media outlet with a large audience base. Its competitive advantages include a wide range of content formats, including live TV, video programs, and regional news. The business model leverages advertising revenues supplemented by subscription services. The site is part of a broader ecosystem including related domains for specialized content and user engagement. Growth indicators include active use of analytics and A/B testing. Partnerships with major ad networks and analytics providers support monetization and audience insights.

Security posture

The website exhibits a good security maturity level with enforced HTTPS and integration of privacy compliance tools like OneTrust. No critical security issues were found in the analyzed content. The use of modern JavaScript modules and deferred loading improves security and performance. However, the absence of DNSSEC and some security headers suggests room for improvement. There is no visible security or incident response policy page, which could be enhanced to improve transparency and readiness. The extensive use of third-party scripts requires ongoing monitoring to mitigate supply chain risks.

Recommendations

  1. Enable DNSSEC to improve domain name system security.
  2. Implement and publish a security policy and incident response information.
  3. Add comprehensive security headers such as Content-Security-Policy and X-Frame-Options.
  4. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  5. Enhance user trust by making data protection officer contact information more visible.

Technical notes

Notes

The website uses a sophisticated custom framework (Yennefer) with modular island components, indicating a modern front-end architecture. It leverages multiple analytics and advertising SDKs, including Gemius, Permutive, and Datadog RUM, for performance and user behavior tracking. Service workers are registered for offline capabilities and performance. The site is optimized for desktop and mobile with responsive design and accessibility considerations. Performance is moderate, with potential improvements in resource loading and caching strategies. SEO is well addressed with proper meta tags and structured data. The hosting provider is not explicitly identified but domain registration is consistent with a professional media company.
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.
