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

ČÚZK (Český úřad zeměměřický a katastrální) is the official Czech government authority responsible for land surveying, cadastral data management, and geospatial information services. The website serves as a portal for citizens, professionals, and government officials to access cadastral maps, property records, geodetic foundations, and open geospatial data. It holds a strong market position as the authoritative source for cadastral and geospatial data in the Czech Republic. Technically, the website is built on legacy ASP.NET WebForms technology with jQuery and Fancybox libraries. While functional, the technology stack is somewhat outdated, with moderate performance and basic mobile optimization. The site uses a custom CMS tailored for government use. Navigation and content structure are clear, but accessibility and SEO optimizations are basic. From a security perspective, the site enforces HTTPS and uses CSRF tokens in forms, but lacks modern security headers and uses an outdated jQuery version with known vulnerabilities. No explicit vulnerability disclosure or security policy pages were found. Privacy compliance is partially addressed with a comprehensive privacy policy page, but no cookie consent mechanism is visible. Overall, the website is trustworthy and professional, reflecting its government status. However, technical modernization and enhanced security practices are recommended to improve resilience and user experience.

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.

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

ČÚZK operates as an essential government entity within the public sector, focusing on cadastral and geospatial data services. Its business model revolves around providing authoritative land registry data, geodetic services, and open data access to a broad audience including citizens, surveyors, real estate professionals, and researchers. The organization benefits from a strong government mandate and a monopoly on cadastral data in the Czech Republic. The website ecosystem includes related portals for cadastral access, digital maps, and public data services, indicating a well-integrated service offering. Growth indicators include ongoing updates and public tenders. The presence on social media and RSS feeds supports communication and transparency. Strategic partnerships appear limited to internal government-related domains.

Security posture

The security posture of the website is moderate. HTTPS is enforced, and anti-CSRF tokens are implemented in forms, indicating basic security hygiene. However, the use of an outdated jQuery version exposes the site to potential client-side vulnerabilities. The absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web attacks. No public incident response or vulnerability disclosure mechanisms were identified, which limits transparency and responsiveness to security issues. Privacy compliance is addressed through a detailed privacy policy, but cookie consent mechanisms are lacking. Overall, the site would benefit from modernization of libraries, implementation of security headers, and formalized incident response processes.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  3. Introduce a visible cookie consent banner to comply with GDPR and enhance user privacy transparency.
  4. Create and publish a security.txt file and vulnerability disclosure policy to improve incident response readiness and trust.
  5. Enhance mobile responsiveness and accessibility features to improve user experience and compliance with standards.

Technical notes

Notes

The website is built on ASP.NET WebForms, a legacy Microsoft web framework, combined with jQuery 1.12.4 and Fancybox for UI components. The CMS appears custom-built for government use, with server-side form handling and CSRF protection. Performance is moderate, with no explicit optimization for mobile devices beyond basic CSS. SEO and accessibility features are basic but functional. The site lacks modern frontend frameworks or progressive web app features. Hosting details are not disclosed. The technical stack is stable but dated, suggesting opportunities for modernization to improve security, performance, and user experience.
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.
