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

Dopravní podnik města Brna, a. s. (DPMB) is the primary public transportation operator in Brno, Czech Republic, providing bus, trolleybus, tram, and boat services to tens of thousands of daily passengers. The company maintains a professional and comprehensive website built on Drupal 10, offering detailed transport information, ticketing options, and service updates. The site is well-branded, mobile-optimized, and accessible, targeting residents and visitors of Brno. Technically, the website employs modern web technologies including Google Tag Manager and CookieHub for analytics and cookie consent management. Security posture is good with HTTPS enforced and cookie consent implemented, though some security headers and explicit security policies are absent. WHOIS data is unavailable due to privacy protection, which is common and justified for this type of public entity. Overall, the website demonstrates a mature digital presence with strong business credibility and compliance with privacy regulations.

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

  2. Security headers

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

DPMB holds a strong market position as the essential public transport provider in Brno, serving a large urban population. Its business model focuses on transportation services, ticket sales, and related offerings such as charter transport and merchandise sales via subdomains. The company leverages partnerships with local cultural and recreational entities, enhancing community engagement. The website's content and structure indicate a focus on transparency and customer service, with multiple channels for information dissemination including social media. The absence of direct contact emails or phone numbers on the main pages suggests a preference for controlled communication via contact forms. The company appears to be well-established and professionally managed, with a clear digital strategy supporting its operational goals.

Security posture

The website benefits from HTTPS encryption and cookie consent mechanisms, reflecting compliance with GDPR and modern privacy standards. However, the lack of visible security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the overall security robustness. No explicit security policy or incident response information is published, which could be improved to enhance transparency and preparedness. There is no evidence of vulnerability disclosure programs or security.txt files, which are recommended best practices. No vulnerabilities or exposed sensitive data were detected in the analysis. The security posture is solid but could be strengthened by adopting additional security headers and publishing formal security policies.

Recommendations

  1. Implement standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response information on the website to improve transparency and user trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Consider providing direct company contact emails or phone numbers for security and support inquiries to improve communication channels.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS platform, ensuring a solid foundation for content management and security updates. The use of Google Tag Manager and CookieHub indicates an integrated approach to analytics and privacy compliance. The site is mobile-optimized with responsive design and accessibility features, providing a good user experience across devices. Performance is moderate, with deferred styles loading and asynchronous script loading to improve page speed. The site structure is clear with well-organized navigation menus and search functionality. Technical risks are minimal, but the absence of some security headers and explicit hosting provider information suggests opportunities for further infrastructure hardening and transparency.
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.
