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

The website www.5gvcesku.cz serves as an informational and promotional platform focused on 5G technology deployment and benefits in the Czech Republic, prominently featuring Huawei as a global leader in 5G technology. It targets businesses, technology stakeholders, and the general public interested in the technological advancement and economic impact of 5G. The site provides educational content, news, and resources related to 5G, emphasizing security and innovation. Technically, the website employs a traditional web stack with jQuery, jQuery UI, Swiper.js for UI components, Google Fonts, and Google Tag Manager for analytics. The site is served over HTTPS with embedded YouTube videos and external resources loaded from trusted domains. While the site is mobile-optimized and has good navigation clarity, some libraries are outdated, and there is a lack of advanced security headers. From a security perspective, the site uses HTTPS and avoids exposing sensitive data. However, it lacks visible security headers and does not provide privacy or cookie policies, which are important for GDPR compliance. No WHOIS data is available, which slightly reduces trustworthiness, though the professional presentation and Huawei branding mitigate concerns. No vulnerabilities or malicious content were detected. Overall, the site is a credible and professional resource for 5G information in the Czech Republic but would benefit from enhanced privacy disclosures, updated security practices, and improved transparency regarding domain registration details.

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

14 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

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 · found on this site
  • 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

The website positions Huawei as a key player in the Czech 5G market, leveraging its global experience to influence local adoption. The business model is primarily informational and advocacy-based, aiming to educate and build trust around 5G technology. The site references EU cybersecurity toolkits and local studies, indicating alignment with regulatory frameworks and market needs. The partnership with LD Studio for site creation suggests professional digital marketing support. The absence of direct contact details or transactional elements implies a focus on brand positioning rather than direct sales. Growth indicators include content updates and integration of multimedia resources. The ecosystem includes Huawei, EU institutions, and local digital agencies.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and no visible sensitive data leaks. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. The lack of privacy and cookie policies indicates potential compliance gaps with GDPR and related regulations. No incident response or vulnerability disclosure information is provided, limiting transparency. The use of outdated JavaScript libraries could pose risks if not regularly updated. Overall, the site is secure for informational purposes but should enhance security controls and compliance documentation to improve trust and resilience.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to ensure GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to strengthen web security.
  3. Update JavaScript libraries to the latest stable versions to mitigate vulnerabilities.
  4. Publish contact information for security incident reporting and establish a vulnerability disclosure program.
  5. Monitor WHOIS data and domain registration status to ensure transparency and trustworthiness.

Technical notes

Notes

The website uses a conventional front-end stack with jQuery and jQuery UI, supplemented by Swiper.js for interactive elements. Google Fonts and Google Tag Manager are integrated for typography and analytics respectively. The site is served over HTTPS with embedded YouTube content using secure iframe attributes. Performance is moderate, with room for improvement by updating libraries and optimizing assets. Mobile optimization is good, but accessibility features are basic. SEO is supported by meta tags and Open Graph data. No CMS or hosting provider details are evident. Technical debt is indicated by outdated jQuery versions and missing security headers, suggesting modernization opportunities.
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.
