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.

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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

MDPO operates primarily in the transportation sector, targeting local residents and passengers in Opava. The business model focuses on public transit services supplemented by ancillary offerings such as advertising spaces and vehicle-related services. The company leverages partnerships with regional transport systems and e-commerce platforms for ticket sales and related products. The website reflects a medium-sized enterprise with a stable market position supported by a long operational history. The partnership ecosystem includes regional transport authorities and city government entities, enhancing service integration and customer reach. Growth indicators include digital service expansion such as online shops and mobile ticketing. Strategic observations suggest opportunities to enhance security posture and incident response transparency to further strengthen stakeholder trust.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a robust cookie consent mechanism aligned with GDPR requirements. The use of third-party analytics and live chat tools is managed with user consent. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces defense-in-depth. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency for security issues. Overall, the site is secure for general use but could benefit from enhanced security controls and formal vulnerability disclosure mechanisms to improve resilience and compliance.

Recommendations

  1. Implement HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy page including incident response procedures and contact channels to improve transparency and trust.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate risks from external libraries.
  4. Enhance accessibility features to meet WCAG standards and improve usability for all users.
  5. Consider adding a security.txt file to facilitate responsible vulnerability disclosure and engagement with security researchers.

Technical notes

Notes

The website is built on Joomla CMS with the Helix Ultimate template framework, utilizing Bootstrap 5.3.3 and jQuery 3.7.1 for responsive design and interactivity. It integrates third-party services such as Google Tag Manager for analytics and Smartsupp for live chat support. The site is mobile-optimized with responsive layouts and includes search functionality powered by Joomla's finder component. Performance appears moderate with no major blocking scripts detected. The technical stack is modern but could be improved by adding security headers and optimizing accessibility. The hosting provider is not explicitly identified. Overall, the technical infrastructure supports the business needs effectively with room for security and accessibility enhancements.
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.
