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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 holds a strong market position as the primary government service platform in the Czech Republic. It offers essential services such as public administration services for individuals and entrepreneurs, life event information, and links to related government services and agencies. The business model is government-funded, focusing on service delivery rather than commercial revenue. The portal maintains partnerships with related government domains and agencies, enhancing its ecosystem. Its content and services are tailored to meet the needs of the Czech population, supporting digital government adoption and accessibility.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of Google reCAPTCHA for form protection, and no visible exposure of sensitive data. However, explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options are not detected, which could enhance security further. There is no published security policy or incident response contact information, which are recommended best practices for transparency and readiness. Overall, the portal follows good security practices appropriate for a government service platform but could improve in formalizing and publishing security policies.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and user trust.
  3. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance contact information by including phone numbers and physical addresses where appropriate to improve user support.
  5. Regularly review and update privacy and cookie policies to maintain GDPR compliance and reflect any changes in data processing.

Technical notes

Notes

The portal uses a modern technology stack including JavaScript ES modules, HTMX for dynamic content, and Sortable.js for UI interactions. It employs Google Tag Manager for analytics and Google reCAPTCHA for bot protection. The site uses custom government design systems (gov-ds3 and gov-ds4) ensuring consistent branding and accessibility. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and language alternates. Hosting details are not explicitly identified, but the site is stable and professionally maintained. Opportunities exist to improve performance and security headers to reduce technical 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.
