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

ČEZNET s.r.o. operates the ČEZNET TV internet television service, offering a variety of HD TV program packages and additional content bundles tailored to different user preferences. The service targets residential customers in the Czech Republic and the EU, providing flexible IPTV solutions accessible on multiple devices including smart TVs, set-top boxes, and mobile devices. The website demonstrates a professional digital presence with clear branding, comprehensive content about service offerings, and user-friendly navigation. Technically, the site uses modern JavaScript libraries and Google Analytics for tracking, with HTTPS enforced and cookie consent mechanisms implemented, reflecting a mature digital infrastructure. Security posture is solid with no visible vulnerabilities, though the absence of security headers and explicit security policies suggests room for improvement. The lack of WHOIS registrant data reduces transparency but does not significantly detract from the overall trustworthiness given the professional presentation and active domain maintenance. Overall, the site is well-positioned in its market niche with a good balance of content quality, technical implementation, and privacy compliance.

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

9 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

ČEZNET s.r.o. holds an important position in the Czech IPTV market, offering tiered subscription packages and add-ons such as sports, film, and adult content bundles. Their business model relies on monthly subscriptions with clear pricing and customer support via phone. The company leverages partnerships within the ČEZNET ecosystem, linking to related domains for internet and other services. The target customer segment includes households seeking flexible and modern TV viewing options without traditional antennas or satellite dishes. Growth potential is supported by multi-device compatibility and EU-wide service availability. The company maintains a moderate size and focuses on telecommunications and media sectors. Strategic observations include the need to enhance transparency through WHOIS data and publish terms of service and security policies to strengthen customer trust and compliance.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms aligned with GDPR requirements, indicating a baseline of security and privacy awareness. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options suggests potential exposure to common web vulnerabilities. No security.txt or incident response contacts are published, limiting transparency in vulnerability handling. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses reputable third-party analytics tools with moderate user tracking. Overall, the security maturity is good but could be enhanced by adopting additional security headers, publishing security policies, and establishing formal incident response channels.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear terms of service page to provide legal clarity and user agreement terms.
  3. Create and publish a security policy or security.txt file with contact information for vulnerability reporting and incident response.
  4. Enhance WHOIS transparency by ensuring registrant data is publicly available or justified with clear privacy protection statements.
  5. Regularly review and update third-party libraries and analytics configurations to minimize tracking and comply with evolving privacy regulations.

Technical notes

Notes

The website employs a modern front-end stack including jQuery, AOS for animations, and Magnific Popup for UI elements, supported by Google Tag Manager and Google Analytics for marketing and analytics. The site is mobile-optimized and supports a wide range of platforms including smart TVs and mobile devices. Performance is moderate with no major issues detected. The absence of a detected CMS suggests a custom or proprietary solution. Hosting provider details are not disclosed. SEO is well addressed with proper meta tags and Open Graph data. Accessibility is basic but functional. Opportunities exist to improve technical security and performance monitoring.
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.
