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

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

ZSSK holds a dominant position in Slovakia's rail transport sector, offering a wide range of passenger services including ticketing, seat reservations, and special accommodations. The company leverages partnerships and integrated transport systems to enhance service offerings. The website reflects a mature digital presence with comprehensive content and user-friendly navigation, supporting customer retention and growth. Revenue streams likely include ticket sales, special service fees, and partnerships. The presence of multilingual support and international travel options indicates strategic market expansion. The company maintains a strong brand identity and trust signals, reinforcing its credibility in the transportation industry.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, multiple security headers, and secure authentication mechanisms. Cookie consent and privacy policies are well implemented, reflecting GDPR compliance. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure program indicates areas for improvement in transparency and readiness. No obvious vulnerabilities or exposed sensitive data were detected. The use of third-party scripts and tracking services is managed with user consent. Overall, the security measures align with industry best practices but could benefit from enhanced documentation and incident management visibility.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to improve transparency and trust.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance monitoring and validation of form inputs to prevent injection and other attacks.

Technical notes

Notes

The website is powered by WordPress 6.7.2 with a modern tech stack including React and jQuery, supported by SEO tools like Yoast SEO Premium. It uses slick carousel for UI elements and integrates a third-party chat widget (Spinoco Webchat) for customer interaction. The site is mobile optimized and accessible, with structured data (JSON-LD) for SEO enhancement. Performance is moderate, with some room for optimization. Hosting details are not explicit but the site uses CDN and external APIs for analytics and marketing. The technical implementation supports a professional user experience but should continue evolving to maintain security and performance standards.
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.
