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

CB Computers v.o.s. operates the CBCNET.CZ website, providing high-speed internet, next-generation cable TV (IP TV), and VoIP telephony services primarily in the Rakovník region of the Czech Republic. The company has a long-standing presence since 1997 and owns the largest metropolitan optical network in Rakovník, complemented by a dense wireless network for broader coverage. Their target audience includes both residential and business customers seeking reliable telecommunications services. The website reflects a professional and consistent brand image with clear service offerings and contact information. Technically, the website is built on WordPress using the Avada theme and incorporates modern plugins such as Revolution Slider and Contact Form 7 with Google reCAPTCHA for spam protection. The site is mobile-optimized, SEO-friendly, and includes cookie consent mechanisms aligned with GDPR requirements. Performance is moderate, with room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS, integrates Google reCAPTCHA, and provides cookie consent controls, demonstrating good privacy practices. However, it lacks explicit security policies, incident response information, and vulnerability disclosure mechanisms. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, CBCNET.CZ presents a trustworthy and professional telecommunications service website with solid technical and privacy foundations. Strategic enhancements in security headers, incident response transparency, and accessibility would further strengthen its security posture and user trust.

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

11 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"

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

CBCNET.CZ holds a strong market position as the largest metropolitan optical network provider in Rakovník, offering a comprehensive suite of telecommunications services including fiber and wireless internet, digital TV, and VoIP. Their business model focuses on infrastructure ownership and direct service provision to both households and corporate clients. The company leverages local market knowledge and infrastructure to maintain competitive advantages. The website indicates active engagement with customers via social media and provides clear contact channels, supporting customer acquisition and retention. The partnership with digital agency 4WORKS Solutions s.r.o. for website development suggests investment in digital presence. Growth opportunities may lie in expanding wireless coverage and enhancing service portfolios.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, integration of Google reCAPTCHA on forms to prevent spam, and a cookie consent mechanism compliant with GDPR. No security headers were detected in the HTML content, representing an area for improvement. There is no publicly available security policy or incident response contact, which could hinder transparency and trust in case of security incidents. No vulnerability disclosure or security.txt file was found, limiting external security researcher engagement. The absence of exposed sensitive data and use of updated plugins indicate good operational security. Overall, the site is secure for typical user interactions but could benefit from enhanced security documentation and headers.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and user trust.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly update WordPress core, themes, and plugins to the latest versions to reduce vulnerability risks.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a stable and widely used CMS platform, WordPress 5.5.3, with the Avada theme and several popular plugins including Revolution Slider and Contact Form 7. It uses jQuery 1.12.4 and integrates Google reCAPTCHA v3 for form security. The site is SEO optimized with Yoast SEO plugin and includes structured data in JSON-LD format for enhanced search engine understanding. Performance is moderate, with potential improvements in loading speed and accessibility. The hosting provider is not explicitly identified but the domain registrar is REG-WEBGLOBE, a known Czech registrar. The site is mobile responsive and uses modern web fonts and CSS techniques. Overall, the technical infrastructure is solid but could benefit from modernization of some libraries and enhanced security headers.
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.
