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

The website portal.gov.cz serves as the official Czech government portal for public administration, providing a comprehensive range of digital services and information to citizens and businesses. It acts as a central hub linking to various government services such as data mailboxes, electronic documents, identity management, and more. The portal is positioned as a primary digital gateway for accessing government services in the Czech Republic, targeting both individual citizens and business entities. Technically, the site employs modern web technologies including JavaScript frameworks, Google reCAPTCHA for form security, Matomo analytics for user behavior tracking, and Google Tag Manager for marketing and analytics management. The design is responsive and accessible, with a strong emphasis on user experience and navigation clarity. Security best practices are observed with HTTPS enforcement, comprehensive security headers, and cookie consent mechanisms. From a security perspective, the portal demonstrates a mature security posture with no visible vulnerabilities or exposed sensitive data. However, explicit security policies and incident response information are not publicly detailed, and no vulnerability disclosure or security.txt file is present. The WHOIS data is unavailable, likely due to registry policies, but the site’s official nature and trust signals mitigate concerns about legitimacy. Overall, portal.gov.cz is a well-maintained, secure, and user-friendly government portal that effectively supports digital public services. Strategic recommendations include publishing detailed security policies, adding vulnerability disclosure mechanisms, and providing data protection officer contact details to enhance transparency and 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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Portal.gov.cz occupies a critical position in the Czech Republic's digital government ecosystem, serving as the main access point for public administration services. Its competitive advantage lies in its official status, comprehensive service offerings, and integration with multiple government systems. The business model is non-commercial, focused on public service delivery and digital transformation of government processes. Revenue streams are not applicable as it is government-funded. The target customer segments include all Czech citizens and businesses requiring interaction with public administration. Growth indicators include continuous updates, new service integrations, and user engagement features such as feedback surveys. The partnership ecosystem is extensive, linking to various government agencies and digital identity providers. Operationally, the portal demonstrates strong governance, technical maturity, and alignment with national digital strategies.

Security posture

The portal exhibits a strong security posture with enforced HTTPS, modern security headers, and use of reCAPTCHA to protect forms against automated abuse. Cookie consent mechanisms comply with privacy regulations, and no sensitive data is exposed in the HTML content. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure channels represents a gap in transparency and readiness. Compliance with GDPR is indicated but could be further strengthened by explicit documentation. The site’s use of third-party analytics and marketing tools is managed with user consent. Overall, the security maturity is high, but improvements in policy publication and incident response communication are recommended to enhance trust and preparedness.

Recommendations

  1. Publish a dedicated security policy page detailing security controls and practices.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear contact information for the Data Protection Officer and incident response team.
  4. Regularly review and audit third-party scripts and analytics tools for security risks.
  5. Enhance transparency by publishing incident response procedures and compliance certifications.

Technical notes

Notes

The website is built using modern web technologies including custom government design systems (gov-ds3 and gov-ds4), JavaScript modules, and third-party libraries such as HTMX and Sortable.js. It integrates Google reCAPTCHA for bot protection and Matomo for privacy-conscious analytics. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with asynchronous loading of scripts and optimized CSS. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicitly identified. Technical risks are minimal, but reliance on multiple external domains requires ongoing monitoring. Opportunities exist to further optimize performance and enhance security transparency.
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.
