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

Cityvizor.cz is a government-backed application focused on providing transparent and detailed financial data about municipalities in the Czech Republic. It serves a broad audience including citizens, municipal officials, and journalists by visualizing municipal budgets, invoices, investments, and official documents. The site is supported by the Ministry of Finance and partners such as Otevřená města, indicating strong institutional backing and trustworthiness. The platform leverages modern web technologies, primarily Vue.js, and is hosted by a reputable Czech hosting provider, WEDOS. The technical infrastructure supports a responsive and user-friendly experience, although some accessibility features could be improved. Security posture is adequate with HTTPS usage and no visible vulnerabilities, but lacks explicit security headers and formal security policies. Privacy compliance is weak due to absence of privacy and cookie policies or consent mechanisms. Overall, the site is professional, trustworthy, and serves an important public transparency function, but could enhance its privacy and security documentation to improve compliance and user trust.

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

10 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

  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

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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
  • 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

Cityvizor operates in the government sector, providing a specialized transparency tool for municipal finance in the Czech Republic. Its competitive advantage lies in direct integration with municipal accounting systems, offering detailed and comprehensible financial visualizations. The business model is service-oriented, likely funded or supported by government budgets and partnerships. The target customers include citizens interested in local governance, municipal employees, elected officials, and media professionals. The platform's partnerships with the Ministry of Finance and Otevřená města strengthen its market position and credibility. Growth potential exists through onboarding additional municipalities and expanding data coverage. The ecosystem includes related city finance portals such as cityvizor.praha.eu, enhancing network effects and data richness.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, ensuring encrypted communications. However, the absence of explicit security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No security or incident response policies are published, and no dedicated security contact channels are provided. There is no evidence of vulnerability disclosure programs or security.txt files. The site does not expose sensitive data or use vulnerable libraries based on the provided HTML. Privacy compliance is limited, with no visible cookie consent or privacy policy, which may pose regulatory risks under GDPR. Overall, the security posture is functional but could be significantly improved by formalizing policies, enhancing headers, and increasing transparency around data protection and incident response.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a cookie consent mechanism to inform users and obtain consent for tracking.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide explicit contact information for security incidents and consider publishing a security.txt file.
  5. Enhance accessibility features to improve compliance with WCAG standards and user inclusivity.

Technical notes

Notes

The website is built using modern JavaScript frameworks, specifically Vue.js, and includes modular JavaScript chunks for optimized loading. It uses Google Fonts for typography and includes a PWA manifest for enhanced mobile experience. Hosting is managed by WEDOS, a reputable Czech hosting provider. Performance is moderate with deferred script loading and responsive design. SEO is supported by proper meta tags and Open Graph data. However, no CMS is detected, indicating a custom or framework-based solution. Accessibility is basic but could be improved. No major technical debt or obsolete technologies are evident. The site lacks explicit security headers which is a technical risk. Overall, the technical implementation is solid 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.
