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

DT - Výhybkárna a strojírna, a.s. is a traditional Czech manufacturer specializing in the development, construction, production, assembly, and regeneration of railway and tramway switch components. With decades of experience, the company serves both domestic and international markets, including metro systems. Their business model focuses on manufacturing and servicing railway infrastructure components, supported by a subsidiary in Slovakia. The website reflects a professional and consistent brand image targeting transportation infrastructure clients. Technically, the website employs a moderately modern technology stack including Bootstrap, jQuery, and Google services such as Analytics and reCAPTCHA. The site is mobile-optimized and includes a comprehensive cookie consent mechanism ensuring GDPR compliance. Performance is moderate with room for improvement in accessibility and security headers. From a security perspective, the site uses HTTPS and implements Google reCAPTCHA for form protection. However, it lacks explicit security headers and does not provide visible incident response or security policy information. The WHOIS data is unavailable, likely due to privacy protection, but the website content and contact details support legitimacy. No critical vulnerabilities or suspicious patterns were detected. Overall, the website presents a trustworthy and professional digital presence suitable for its industry. Strategic improvements in security headers, updated libraries, and enhanced accessibility would further strengthen its posture.

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

9 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

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 · found on this site
  • 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 solid market position as a specialized manufacturer in the railway and tramway sector, with a clear focus on infrastructure components. Their subsidiary in Slovakia expands their regional footprint. The business model is product and service-oriented, targeting infrastructure operators and industrial clients. The website content and structure indicate a mature organization with certifications and compliance adherence. The presence of a spare parts configurator and multilingual support suggests a customer-centric approach. Partnerships and certifications reinforce credibility, while the use of Google Analytics and cookie consent reflects awareness of digital marketing and privacy regulations.

Security posture

The security posture is moderate to good. HTTPS is enforced, and Google reCAPTCHA is used to protect forms, reducing spam and automated attacks. The cookie consent mechanism aligns with GDPR requirements, enhancing privacy compliance. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain attacks. No incident response or security contact information is provided, which limits transparency in case of security events. The use of somewhat outdated JavaScript libraries could pose risks if not regularly updated. Overall, the site is secure for typical business use but could benefit from enhanced security controls and transparency.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Provide explicit security policy and incident response contact information on the website to improve transparency and trust.
  3. Update JavaScript libraries such as jQuery to the latest stable versions to reduce vulnerability exposure.
  4. Enhance accessibility features to improve usability for all users and comply with accessibility standards.
  5. Maintain and regularly audit GDPR compliance mechanisms, including cookie consent and privacy policy updates.

  6. No explicit security headers detected in provided data; recommend adding.
  7. Google Analytics is used with consent mechanism in place.
  8. No terms of service page found.
  9. The site targets transportation and manufacturing sectors, specifically railway infrastructure.
  10. The website is multilingual (CZ, EN, DE).
Technical notes

Notes

The website uses a combination of Bootstrap for responsive design and jQuery 1.11.3, which is an older version but still functional. Additional libraries like Isotope, SmoothScroll, Stacktable, and Fancybox enhance UI/UX. Google Fonts and Font Awesome provide typography and iconography. Google Analytics and reCAPTCHA are integrated for analytics and security. The site is mobile-optimized with good SEO meta tags and multilingual support. Performance is moderate, with potential improvements by updating libraries and optimizing assets. No CMS is detected, suggesting a custom or static site architecture. Hosting provider details are not available from the data. Overall, the technical implementation is solid but could benefit from modernization and enhanced security practices.
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.
