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

ODISka.cz is a regional public transport card management website serving the Moravian-Silesian region in the Czech Republic. It provides users with services such as card registration, login, ticket purchase, and fare overview, integrating multiple transport modes including bikesharing. The website is professionally designed with consistent branding and clear navigation, targeting public transport users including students and children. The domain is well-established since 2012 and aligns with the business's regional transport focus. Technically, the site uses a modern tech stack including jQuery, Bootstrap, and various UI libraries, hosted likely by Active24. The site is mobile optimized and performs moderately well, though accessibility and SEO optimizations are basic. Security posture is adequate with HTTPS enforced but lacks important security headers such as CSP and HSTS, which should be addressed to improve resilience. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the security posture is stable but could benefit from enhanced headers and explicit GDPR cookie consent. No critical vulnerabilities or suspicious content were found. The site does not expose sensitive data and uses modal dialogs for user interactions, indicating some security awareness. Strategically, the site is a credible and trustworthy regional transport service portal with room for technical and compliance improvements to enhance user trust and security robustness.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

    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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The website represents a key regional transport service provider, Kodis, offering integrated ticketing and card management for public transport users. Its market position is strong within the Moravian-Silesian region, serving a broad audience including students and commuters. The business model focuses on service provision rather than direct sales, with revenue likely from transport authorities and ticket sales. The partnership ecosystem includes regional government and transport operators, as evidenced by linked domains and logos. Growth indicators include new ticket products and integration with bikesharing. The site supports user self-service, reducing operational costs and improving customer experience.

Security posture

The current security maturity is moderate. HTTPS is enforced, which is mandatory, but the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces protection against common web attacks. No incident response or security policy information is publicly available, indicating potential gaps in transparency. The site uses secure modal dialogs for sensitive actions but lacks visible vulnerability disclosure or security contact channels. Compliance with GDPR is partial, with a privacy policy but no cookie consent mechanism. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is functional but can be significantly improved with standard best practices.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and HSTS.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR requirements.
  3. Publish a security policy and incident response contact information to improve transparency and trust.
  4. Regularly audit and update JavaScript libraries to mitigate vulnerabilities.
  5. Enhance accessibility and SEO features to improve user experience and discoverability.

Technical notes

Notes

The website uses a modern and popular technology stack centered on jQuery and Bootstrap, supplemented by UI enhancement libraries such as Slick Carousel and Select2. The site is custom-built without a known CMS, hosted likely by Active24, a reputable Czech hosting provider. Performance is moderate with room for optimization. Mobile responsiveness is good, but accessibility features are basic. SEO meta tags are minimal, and no structured data like JSON-LD or Open Graph tags were detected. The site uses modal dialogs extensively for user interactions, indicating a dynamic and interactive user interface. Technical debt appears low but could be improved with modern security and SEO 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.
