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

8 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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's market leadership is supported by a broad portfolio of print and digital media titles, including flagship newspapers like Blesk and popular magazines. The business model revolves around content publishing and advertising revenue, targeting a general audience interested in news and entertainment. The company ecosystem includes subsidiaries such as Czech Video Center and Active Radio, enhancing multimedia reach. The website's external links and partner domains reflect a strong partnership network. Growth indicators include extensive digital presence and use of advanced consent management tools, positioning CNC well for future digital media trends.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms. However, there is no explicit security policy or vulnerability disclosure page, which could improve transparency and incident readiness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of modern JavaScript frameworks and third-party SDKs is balanced with privacy compliance tools. Incident response contact information is absent, which is a gap in security maturity. Overall, CNC maintains a secure environment appropriate for a media company but could enhance its security communication and incident management capabilities.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ emails.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Increase visibility of official contact information to improve business credibility.

Technical notes

Notes

The website uses a modern tech stack including React and Next.js, enabling server-side rendering and good performance. Google Tag Manager and Didomi SDKs are integrated for analytics and consent management, reflecting compliance with privacy regulations. Hosting is managed via Webglobe, a reputable provider. The site is mobile-optimized with responsive design and prefetching of scripts for performance. SEO is supported by proper meta tags and Open Graph data. Some technical debt may exist in accessibility and explicit security headers, which can be improved. Overall, the technical infrastructure is robust and supports CNC's business goals effectively.
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.
