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. 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

      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.

Add-on

Leaked records that mention cnc.cz, from OffSeq Breach.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CNC holds a strong market position as a specialist in video communication solutions in the Czech Republic, leveraging long-term industry experience and a broad client base across multiple sectors including industry, banking, education, and government. Their business model focuses on B2B sales, consultations, equipment rental, and after-sales support. The company’s website reflects a mature digital marketing approach with multi-language support and integration of analytics and tracking tools. No parent or subsidiary companies are identified. The company’s consistent branding, clear contact information, and GDPR compliance enhance its credibility and customer trust.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, CSRF tokens on forms, and Google reCAPTCHA integration to prevent spam. Use of security headers is not evident and no explicit security or incident response policies are published, representing areas for improvement. No vulnerabilities or sensitive data exposures were detected in the HTML content. Tracking scripts from reputable providers are used responsibly with cookie consent mechanisms in place. Overall, the security maturity is good but could be enhanced by publishing formal security policies and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and trust.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet WCAG standards for broader compliance.
  5. Maintain and document data retention policies for analytics and user data to strengthen privacy compliance.

Technical notes

Notes

The website uses a modern and widely adopted technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and Swiper for sliders. It integrates multiple analytics and marketing tools such as Google Analytics, Microsoft Clarity, Facebook Pixel, and LinkedIn Insight Tag, indicating a data-driven marketing approach. The site is hosted likely by Active24, consistent with the registrar information. Performance is moderate with deferred loading of scripts and optimized images. Mobile optimization is good, and SEO practices are evident through meta tags and structured navigation. No CMS is explicitly detected, suggesting a custom or proprietary solution. Opportunities exist to improve accessibility and implement additional security headers to reduce technical risks.
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.
