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

11 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

      Missing Strict-Transport-Security header

      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

      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

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 transparency tools for municipal finances. Its competitive advantage lies in direct integration with municipal accounting systems and detailed invoice-level data visualization. The business model is service-oriented, likely funded by government budgets or grants, targeting a niche audience of Czech municipalities and their stakeholders. The partnership ecosystem includes the Ministry of Finance and Otevřená města, enhancing credibility and reach. Growth potential exists through onboarding more municipalities and expanding data coverage. The platform's strategic positioning as a transparency enabler aligns with public sector digital transformation trends.

Security posture

The website demonstrates a moderate security posture with HTTPS usage and no visible exposed sensitive data. However, it lacks visible security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended best practices. There is no published security policy, incident response contact, or vulnerability disclosure information, which limits transparency on security governance. The absence of privacy and cookie policies also indicates compliance gaps with GDPR requirements. Overall, the security maturity is adequate for a public informational site but could be improved to enhance trust and compliance.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Implement and configure security headers (CSP, HSTS, X-Frame-Options) to strengthen security posture.
  3. Provide clear contact information for security incidents and vulnerability disclosures.
  4. Enhance accessibility features to improve inclusivity and compliance with standards.
  5. Regularly audit third-party scripts and tracking to ensure minimal privacy impact.

Technical notes

Notes

The website is built using modern JavaScript frameworks, specifically Vue.js, with modular JavaScript files and CSS. It uses Google Fonts for typography and serves SVG images for graphics, ensuring scalability and performance. Hosting is provided by WEDOS, a Czech hosting provider, consistent with the domain registration. The site is mobile-optimized and has good SEO meta tags including Open Graph for social sharing. However, no CMS is detected, suggesting a custom or static site build. Performance is moderate, with deferred script loading improving page load times. Technical risks include lack of security headers and missing privacy compliance features, which should be addressed to reduce operational risks.
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.
