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

gov.cz is the official Czech government portal for public administration, providing comprehensive digital services and information to citizens and businesses. It serves as a central hub for accessing government services such as digital identity, document issuance, and public records. The portal is well-established, with a domain age dating back to 2001, reflecting its long-standing role in the Czech eGovernment ecosystem. The site is professionally designed with consistent branding and clear navigation, targeting a broad audience of Czech residents and enterprises. Technically, the website employs modern web technologies including JavaScript ES modules, Google Tag Manager for analytics, and Google reCAPTCHA for form security. It uses government-specific design systems (gov-ds3 and gov-ds4) ensuring accessibility and mobile optimization. Performance is fast, and SEO practices are well implemented. However, explicit security headers are not detected, and there is no visible security policy or vulnerability disclosure mechanism. From a security perspective, the portal enforces HTTPS and uses secure form submission methods. The presence of Google reCAPTCHA helps mitigate automated abuse. No vulnerabilities or exposed sensitive data were found in the HTML content. Privacy compliance is strong, with clear privacy and cookie policies aligned with GDPR. Contact information is limited but includes an official government email address. No phone numbers or physical addresses are provided. Overall, gov.cz demonstrates a high level of professionalism, security, and compliance appropriate for a government digital service portal. Recommendations include enhancing security headers, publishing a formal security policy, and implementing a vulnerability disclosure program to further strengthen trust and security posture.

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

6 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

      Missing X-Frame-Options header

      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

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3

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

gov.cz holds a dominant position as the official digital gateway for Czech public administration, serving millions of citizens and businesses. Its business model is government-funded, focusing on delivering digital public services and information dissemination. The portal integrates with multiple government agencies and services, creating a broad partnership ecosystem. Its competitive advantage lies in official status, comprehensive service coverage, and integration with national digital identity and data mailbox systems. The portal targets all Czech residents and enterprises requiring government services, indicating a large and diverse user base. Growth indicators include continuous updates, integration of new digital services, and active social media presence. Strategic observations highlight the importance of maintaining high security and privacy standards given the sensitive nature of government services.

Security posture

The security posture of gov.cz is solid, with mandatory HTTPS and secure form handling. The use of Google reCAPTCHA adds protection against automated attacks. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap that could be exploited in certain attack scenarios. No incident response or security contact information is published, which limits transparency and responsiveness to security issues. Privacy policies are comprehensive and GDPR compliant, indicating good data protection practices. No vulnerabilities or suspicious patterns were detected in the website content. Overall, the portal shows a mature security culture but could improve in formalizing security policies and vulnerability disclosure.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Expand contact information to include phone numbers or physical addresses for better user support and trust.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize user tracking.

The technical implementation reflects a mature and well-maintained infrastructure suitable for a high-traffic government portal.
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.
