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

České dráhy, a.s. is the largest Czech railway operator with nearly two centuries of history, providing both passenger and freight transport services. The company operates a broad portfolio of services including IT, certification, vehicle repairs, education, and travel agency services through its subsidiaries. The website reflects a mature, enterprise-level organization with a strong market position in the Czech Republic and expanding European presence. Technically, the site is built on Drupal 10 with modern JavaScript libraries and integrates Google Analytics and Tag Manager for tracking. The site is mobile-optimized, accessible, and professionally designed, offering clear navigation and comprehensive content. Security posture is adequate with HTTPS and cookie consent mechanisms, but lacks explicit security policies and advanced security headers. Overall, the domain registration data aligns well with the company's long history and business claims, supporting high legitimacy and trustworthiness.

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

10 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 holds a dominant position in the Czech transportation sector, operating millions of trains and transporting hundreds of millions of passengers annually. Its business model integrates multiple subsidiaries specializing in various railway-related services, enhancing operational efficiency and market coverage. The target audience includes individual travelers, corporate clients, partners, investors, and potential employees. The company demonstrates strong branding consistency and trust signals such as official contact details, social media presence, and detailed career information. Growth is indicated by ongoing investments in modern rolling stock and digital services. The partnership ecosystem includes several specialized subsidiaries, reinforcing the group's comprehensive service offering.

Security posture

The website employs HTTPS and anonymizes IP addresses in analytics, indicating a baseline security awareness. Cookie consent is implemented, supporting privacy compliance. However, the absence of visible security headers (e.g., CSP, HSTS) and lack of published security policies or incident response contacts suggest room for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. The site uses common third-party scripts which should be regularly audited. Overall, the security posture is moderate but could be enhanced by adopting best practices and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy page including incident response contacts to improve transparency and readiness.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to prevent vulnerabilities from outdated components.
  5. Enhance form security by ensuring anti-CSRF tokens and robust input validation are in place.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, ensuring a solid foundation for content management and security updates. The use of jQuery, Swiper.js, and Glightbox indicates a focus on interactive and responsive user experience. Google Analytics and Tag Manager integration provide detailed user behavior insights. The site is mobile-optimized with responsive design and accessibility features, supporting a broad user base. Performance is moderate, likely influenced by the use of multiple scripts and media assets. There is an opportunity to optimize loading times and implement advanced caching or CDN strategies. The technical stack is modern but requires ongoing maintenance to mitigate risks associated with third-party dependencies.
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.
