CZECH NEWS CENTER a.s. (CNC) is a leading media house in the Czech Republic and Central Europe, publishing a wide range of print and digital media including newspapers, magazines, websites, and radio partnerships. The company is part of the Czech Media Invest group and operates with a strong focus on digital transformation and cross-media advertising. CNC targets a broad audience with diverse content spanning news, sports, lifestyle, technology, and children’s media.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

CNC holds a dominant market position in the Czech media landscape with a portfolio of over 100 titles and digital projects, reaching millions monthly. Its business model leverages multi-channel content distribution and advertising, including print, online, radio, and events. The company benefits from strategic partnerships and subsidiaries such as Gjirafa Tech and Czech Video Center, enhancing its technological capabilities and multimedia offerings. CNC’s growth is supported by digital transformation initiatives and a strong focus on data-driven advertising solutions. The company targets advertisers seeking broad and targeted reach across multiple media types. Its extensive brand portfolio and event organization further diversify revenue streams and audience engagement.

Security posture

The website employs HTTPS and integrates modern consent management frameworks (Didomi, Privacy Center SDK), indicating compliance with privacy regulations like GDPR. However, explicit security headers such as Content-Security-Policy and X-Frame-Options were not detected in the provided data, suggesting room for improvement. No exposed sensitive data or vulnerabilities were found in the analysis. The site uses secure forms and collects user data responsibly with clear privacy policies. Incident response and security policy documentation were not found on the site, which could be enhanced to improve security maturity. Overall, the security posture is solid but could benefit from additional hardening and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response plan accessible to users and partners to enhance trust and preparedness.
  3. Conduct regular security audits of third-party scripts and SDKs to prevent vulnerabilities.
  4. Enhance transparency by providing WHOIS registrant information or justifying privacy protection to improve domain trustworthiness.
  5. Continue investing in privacy compliance and user consent mechanisms to maintain GDPR adherence and user trust.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring fast performance and excellent mobile responsiveness. It uses advanced JavaScript libraries and integrates third-party SDKs for privacy and consent management. The site structure is well-organized with clear navigation and SEO-friendly meta tags. No CMS was explicitly detected, suggesting a custom or headless CMS approach. Hosting provider details are not available. The site demonstrates good accessibility features and a professional design consistent with a large media enterprise. Opportunities exist to improve security headers and provide more detailed technical documentation for transparency.
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.
