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

The website www.datalk.cz is a modern data portal operated by the Krajský úřad Libereckého kraje (Regional Office of Liberec Region) providing comprehensive open data and information about the Liberec region. It serves both professional and general public audiences with interactive data presentations, open datasets, analyses, and thematic articles covering diverse sectors such as transportation, health, social services, environment, and culture. The portal acts as a central hub for regional data and related applications. Technically, the site is built on the ArcGIS Hub platform using Ember.js and Calcite Components, indicating a mature and specialized GIS-focused infrastructure. The site is well-structured, mobile-optimized, and includes SEO best practices. HTTPS is enforced, but some security headers are missing, and no cookie consent mechanism is detected, which are areas for improvement. Security posture is generally good with enforced HTTPS and browser blocking for unsupported browsers, but the absence of WHOIS data for the domain reduces trustworthiness from a domain registration perspective. No direct contact emails or phone numbers are exposed, with contact facilitated via forms. Privacy policy and terms of service are present and appear GDPR compliant. Overall, the site is a trustworthy and professional government data portal with moderate technical and security maturity. Strategic recommendations include adding security headers, implementing cookie consent, and verifying domain registration details to enhance trust and compliance.

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

9 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

    • 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"

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 portal is positioned as an essential government service providing open data and analytics for the Liberec region. Its competitive advantage lies in official backing by the regional government and integration with ArcGIS Hub, enabling rich geospatial data visualization. The business model is public sector service provision without direct revenue streams, targeting government officials, researchers, educators, and the general public. Growth indicators include extensive content and partner ecosystem with regional agencies and ministries. The partnership network includes regional development agencies and educational ministries, reinforcing its authoritative role in regional data dissemination.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and browser compatibility checks redirecting unsupported browsers. However, the lack of common security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection is a gap. No incident response or security policy information is published, and no vulnerability disclosure or security.txt files are found. Privacy compliance is indicated by a privacy policy and GDPR references, but cookie consent is missing. The absence of WHOIS data for the domain is a concern for domain legitimacy and trust. Overall, the security posture is adequate but could be improved with enhanced headers, transparency, and domain registration clarity.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-XSS-Protection) to mitigate common web attacks.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Verify and publish domain registration information to improve trust and legitimacy perception.
  4. Publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and analytics to ensure no vulnerable or privacy-invasive components are included.

Technical notes

Notes

The website leverages a modern GIS-focused technology stack based on ArcGIS Hub and Ember.js, providing a robust platform for interactive data visualization and management. The use of Calcite Components indicates adherence to modern UI standards. Performance is moderate with external CDN usage for assets. The site is mobile-optimized and SEO-friendly with comprehensive meta tags and Open Graph data. However, the absence of some security headers and cookie consent mechanisms indicates areas for technical improvement. The WHOIS data absence suggests a need for domain management review. Overall, the technical infrastructure is solid but can benefit from enhanced security and privacy features.
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.
