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

8 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

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

DPMO holds a strong market position as the primary public transport operator in Olomouc, leveraging partnerships with local government and regional transport systems. Its business model includes core transportation services supplemented by advertising and vehicle rental, supported by digital tools like e-ticketing and an online e-shop. The company targets a broad audience of daily commuters and residents, with growth indicators seen in EU co-financed projects and digital service enhancements. The partnership ecosystem includes city authorities and regional transport associations, reinforcing its operational legitimacy and market reach. The website content and structure reflect a mature organization focused on service quality and customer engagement.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and a cookie consent mechanism ensuring GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. There is no dedicated incident response or security policy page, which could enhance transparency and readiness. The use of third-party scripts like Google Analytics and ShareThis is managed with user consent. Overall, the security measures are adequate for the business type but could be strengthened to mitigate advanced threats and improve compliance.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Create and publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Consider adding terms of service to clarify user rights and obligations.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform using a combination of jQuery and related plugins for UI components such as date-time pickers and enhanced select boxes. Google Tag Manager and Google Analytics are integrated for tracking and marketing purposes. The site loads multiple CSS and JS resources asynchronously to improve performance. Mobile optimization is good with responsive design elements. SEO is supported by meta tags and structured navigation. However, the lack of modern frontend frameworks or CMS platforms may indicate technical debt or limited scalability. Performance is moderate, with potential for optimization in resource loading and caching strategies.
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.
