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 is strategically positioned as the unified ticketing solution for Czech railway passengers, leveraging partnerships with multiple carriers and government entities. Its business model centers on selling universal tickets valid across carriers, supplemented by add-ons like seat reservations and discount cards. Revenue streams include ticket sales, corporate and family account subscriptions, and ancillary services. The platform appeals to a broad customer base including daily commuters, occasional travelers, families, and corporate clients. Growth indicators include increasing ticket sales and expanding service offerings such as integration with commercial carriers like Leo Express. The partnership ecosystem includes the Ministry of Transport, CENDIS, and tourism agencies, enhancing market reach and service relevance. The system's operational transparency and government backing provide competitive advantages in trust and regulatory compliance.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and no exposed sensitive data in the HTML content. While explicit security headers like Content-Security-Policy and X-Frame-Options are not visibly declared, the platform likely relies on backend configurations. No vulnerable or outdated libraries are detected in the client-side code. The absence of a published security policy or incident response contact limits transparency in vulnerability handling. Cookie consent is implemented, supporting privacy compliance. Overall, the security measures are adequate for the service type but could be enhanced by publishing formal security policies and adopting additional HTTP security headers. No critical vulnerabilities or malware indicators are present.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts to improve transparency and trust.
  2. Implement and explicitly declare HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Consider adding a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  4. Enhance cookie consent mechanisms with granular user controls and detailed data retention disclosures.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities or privacy risks.

Technical notes

Notes

The website is built using React, leveraging modern JavaScript and CSS chunking for performance. Google Fonts and SVG icons are used for consistent branding and UI clarity. The site is mobile-optimized with responsive design and accessible navigation. Hosting is provided by REG-WEDOS, a known Czech hosting provider, consistent with the domain WHOIS data. Performance is moderate, with room for optimization in script loading and caching. SEO is well addressed through meta tags, Open Graph, and JSON-LD structured data. No CMS is detected, indicating a custom or framework-based solution. Technical risks are minimal, but explicit security headers and formal security documentation are recommended to reduce potential attack surface and improve compliance.
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.
