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

5 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The company is positioned as the essential national rail operator in the Czech Republic, leveraging a public transportation business model with additional e-commerce for ticketing. Its competitive advantage lies in its extensive network, brand recognition, and integrated digital services. Revenue streams primarily come from passenger ticket sales and related services. The target customers include general public travelers, business clients, and group travel organizers. The company maintains partnerships with related entities such as CD Nostalgie for historical train services. The website content and structure indicate a mature digital presence with ongoing marketing and customer engagement through social media and mobile applications.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure login forms. Cookie consent is implemented, supporting GDPR compliance. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the content. Security headers are not explicitly visible, suggesting potential enhancement areas. Overall, the security maturity is good but could be strengthened by formalizing security governance and communication.

Recommendations

  1. Publish a dedicated security policy page and incident response contact information to improve transparency and trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance data retention and privacy policy details to explicitly inform users about data handling practices.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with libraries such as Slick Carousel and jQuery UI Autocomplete. Google Tag Manager is used for analytics and marketing tracking. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with potential for optimization in loading times and resource management. No CMS or hosting provider details are explicitly detected. The technical implementation supports a professional user experience but could benefit from enhanced security headers and performance tuning.
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.
