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

6 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: Facebook, Twitter, Google APIs

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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 OneTicket system holds a strong market position as the national unified railway ticketing solution in the Czech Republic, supported by government entities. Its business model revolves around selling universal train tickets and related services, targeting both individual travelers and corporate/family groups. Revenue streams include ticket sales, discount cards, and supplementary services like seat reservations. The platform shows growth through expanding carrier participation and service offerings. Partnerships with the Ministry of Transport, CENDIS, and tourism portals enhance its ecosystem. The company maintains a medium-sized operational scale with a clear focus on transportation sector digital services.

Security posture

The website exhibits a mature security posture with enforced HTTPS and no exposed sensitive data. The absence of explicit security headers and a public security policy or vulnerability disclosure page suggests room for improvement. No incident response contacts or security@/abuse@ emails are provided, which could hinder rapid response to security issues. The use of modern frameworks and lack of vulnerable libraries indicate good development practices. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security maturity is good but could be enhanced by formalizing security policies and incident response mechanisms.

Recommendations

  1. Implement and publish a formal security policy and vulnerability disclosure page.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Provide explicit incident response contact channels (e.g., security@oneticket.cz).
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by detailing data retention policies and user privacy controls.

Technical notes

Notes

The website is built using React, served with modern JavaScript bundling via Webpack, and uses Google Fonts for typography. The site is mobile-optimized with responsive design and accessible navigation. Performance is moderate, with room for optimization in loading times. The CMS appears custom-built, tailored for the ticketing business. Hosting details are limited but the domain registrar is REG-WEDOS, a Czech provider. SEO is well addressed with proper meta tags and Open Graph data. Accessibility features are present but could be further enhanced with ARIA landmarks and roles. Overall, the technical infrastructure supports a robust user experience with opportunities for performance tuning and security header enhancements.
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.
