Security score

48/100

Risk levelHigh

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

ČEZNET s.r.o. operates an IPTV service branded as ČEZNET TV, offering a variety of television packages with HD quality and smart features accessible via multiple devices. The company targets Czech customers seeking flexible and modern internet television solutions. The website is professionally designed, mobile-optimized, and includes clear navigation and content relevant to IPTV services. Technically, the site uses modern JavaScript libraries and Google Tag Manager for analytics, with HTTPS enforced and cookie consent implemented. However, no advanced security headers were detected, and WHOIS data is unavailable, indicating privacy protection. The presence of an adult content package is clearly labeled and separated from general content. Overall, the site demonstrates a good security posture but could improve by adding security headers and explicit vulnerability disclosure mechanisms.

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. positions itself as a regional IPTV provider in the Czech Republic, offering subscription-based television services with multiple tiered packages and add-ons. Its competitive advantage lies in flexible offerings, multi-device support, and cloud recording features. The company appears medium-sized with a focused telecommunications sector presence. The partnership ecosystem includes its main corporate site and streaming platform. Revenue streams are likely subscription fees from various TV packages and add-ons. Growth indicators include recent content updates and new package offerings. The company maintains a professional online presence with clear branding and customer support via phone.

Security posture

The website enforces HTTPS and includes a cookie consent mechanism, reflecting awareness of privacy compliance. However, the absence of visible security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No exposed sensitive data or vulnerable libraries were detected. The lack of a published security policy or incident response contact limits transparency. WHOIS privacy protection is used, which is common but reduces domain registration transparency. Overall, the security maturity is moderate with room for improvement in headers and disclosure.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Consider adding a security.txt file to facilitate vulnerability disclosures.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern front-end stack including jQuery, AOS for animations, Magnific Popup for modals, and Fluidable for layout. Google Tag Manager is used for analytics and marketing tags. The site is mobile-optimized and supports multiple streaming platforms including smart TVs and mobile devices. Performance is moderate with room for optimization. No CMS or hosting provider information was detected. The site uses canonical URLs and meta tags for SEO. Accessibility is basic but could be improved. No critical technical debt or risks were identified, but security header implementation is lacking.
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.
