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. 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 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';…

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

DVTV holds a strong market position as the first internet television in the Czech Republic, leveraging subscription and donation revenue streams. Its competitive advantage lies in exclusive political interviews and multimedia content accessible via web and mobile apps. The company maintains active social media engagement and transparent legal documentation, supporting customer trust. While the domain WHOIS data is privacy protected, the business legitimacy is supported by consistent branding and professional content. Growth opportunities include expanding digital services and enhancing security transparency.

Security posture

The website exhibits a mature security posture with enforced HTTPS and no exposed sensitive data. Use of Google Tag Manager and DoubleClick indicates controlled third-party script management. However, the absence of explicit security headers and incident response information suggests room for improvement. No vulnerability disclosures or security.txt files were found, which could enhance transparency and readiness. GDPR compliance is evident, but ongoing audits of third-party scripts and enhanced accessibility features are recommended to strengthen security culture.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy and X-Frame-Options.
  2. Publish an incident response policy and consider adding a security.txt file for vulnerability disclosures.
  3. Enhance accessibility compliance to improve inclusivity and SEO benefits.
  4. Regularly review and audit third-party scripts to mitigate supply chain risks.
  5. Increase transparency around data retention policies and user privacy controls.

Technical notes

Notes

The website is built on a modern React and Next.js stack with Material-UI for styling, ensuring responsive design and good user experience. Integration with Firebase Storage supports media content delivery. Google Tag Manager and Google Ads are used for analytics and advertising, reflecting a mature digital marketing approach. Performance is moderate with deferred script loading and prefetching techniques. No CMS was detected, suggesting a custom or headless architecture. Hosting provider details are not explicit. Technical risks include reliance on multiple third-party scripts which require regular security reviews.
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.
