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

Vodafone Czech Republic is a major telecommunications provider offering mobile phones, tariffs, high-speed internet including 5G, and television services. The website is professionally designed, mobile-optimized, and provides comprehensive information about their offerings targeted at the Czech market. The digital infrastructure uses modern analytics and tracking technologies such as Adobe Omniture and Tealium, indicating a mature digital presence. Security posture is strong with HTTPS enforced and security headers implemented, though no explicit security policy or incident response information is published. The absence of WHOIS data reduces domain trust slightly but the overall branding and content strongly support legitimacy. Strategic recommendations include publishing security and incident response policies and enhancing accessibility 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

6 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

  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

      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

      • ASVS V3.4.3

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

Vodafone Czech Republic operates as a large enterprise in the telecommunications sector, serving a broad consumer base in the Czech Republic. Their business model focuses on providing mobile and fixed-line communication services, leveraging the Vodafone Group's global brand and infrastructure. The website reflects a strong market position with key services including 5G network access, unlimited tariffs, and bundled TV services. Partnerships such as with oskarta.cz indicate an ecosystem approach. The company maintains a professional online presence with clear navigation and comprehensive service descriptions, supporting customer acquisition and retention.

Security posture

The website demonstrates a good security maturity level with HTTPS, CSP, and other security headers in place. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a publicly available security policy or incident response contact reduces transparency and preparedness perception. GDPR compliance is evident through cookie consent mechanisms and privacy policies. No vulnerability disclosure or security.txt files were found, suggesting room for improvement in vulnerability management and communication. Overall, the security posture is solid but could be enhanced by publishing formal security governance documents.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response and vulnerability disclosure contact information.
  3. Enhance website accessibility to meet WCAG standards for broader compliance.
  4. Regularly audit third-party scripts and tracking tools for privacy compliance.
  5. Maintain updated WHOIS information or provide transparency about domain registration.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Adobe Omniture for analytics, and Tealium for tag management. CSS and JavaScript are minified and fonts are loaded efficiently with localStorage caching. Performance is moderate with good mobile optimization and SEO meta tags including Open Graph for social sharing. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed in the HTML. The site implements cookie consent and privacy banners consistent with GDPR requirements. Technical risks are minimal but monitoring third-party dependencies is advised.
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.
