Risk levelLow

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

The website represents the official Czech government tax portal operated by the Generální finanční ředitelství (General Financial Directorate). It provides a comprehensive suite of online tax services including the Online Financial Office, electronic submissions, VAT registries, EU VAT refund services, and DAC7 reporting. The portal targets Czech taxpayers and entities interacting with the financial administration, offering secure and user-friendly digital tax management tools. The site is built on a modern Angular framework, ensuring responsive design and accessibility across devices. Security is robust with HTTPS enforced and secure login required for sensitive services, although explicit security headers and incident response contacts are not prominently published. The absence of WHOIS data is unusual but does not detract from the portal's legitimacy given its official branding and government affiliation. Overall, the portal demonstrates a mature digital infrastructure supporting critical government functions with strong privacy and compliance adherence.

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

      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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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 Generální finanční ředitelství operates this portal as a key digital interface for tax administration in the Czech Republic, positioning itself as the authoritative source for tax-related electronic services. Its business model is government service provision, focusing on compliance facilitation and taxpayer convenience. The portal's comprehensive service offerings and integration with official financial systems provide a competitive advantage in government digital services. The target audience includes individual taxpayers, businesses, and tax professionals. The portal's partnership ecosystem includes related government domains such as epodpora.mfcr.cz for technical support. Growth indicators include continuous updates and new service integrations like DAC7 reporting. Strategic observations highlight the importance of maintaining high security and privacy standards to uphold public trust in government digital services.

Security posture

The portal exhibits a strong security posture with mandatory HTTPS, secure authentication for sensitive services, and no visible exposure of sensitive data. However, the lack of explicit security headers such as Content-Security-Policy and absence of a published security policy or incident response contact reduces transparency. No vulnerabilities or outdated libraries were detected in the provided content. GDPR compliance is evident through comprehensive privacy and cookie policies with user consent mechanisms. Incident response readiness and vulnerability disclosure mechanisms are not publicly documented, representing an area for improvement. Overall, the security maturity is high but could benefit from enhanced transparency and formalized security communication.

Recommendations

  1. Implement and publish comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information, including a security.txt file, to improve transparency and facilitate vulnerability reporting.
  3. Regularly audit and update third-party libraries and dependencies to mitigate risks from known vulnerabilities.
  4. Enhance user awareness and trust by providing clear information on data protection officer contacts and data retention policies.
  5. Consider integrating advanced monitoring and alerting systems to detect and respond to phishing or impersonation attempts targeting users.

Technical notes

Notes

The website is built using Angular 17.3.2, leveraging modern web technologies including Material Icons and CSS custom properties for styling. The application is modular and optimized for mobile responsiveness and accessibility. Performance is moderate, with deferred and module-based script loading. The site uses no detectable CMS, indicating a custom or government-developed platform. Hosting details are not explicitly available, but the domain is under the Czech Ministry of Finance's subdomain. Technical risks are minimal, though the absence of some security headers and WHOIS data represent potential areas for operational improvement. Overall, the technical infrastructure supports a secure, scalable, and user-friendly government service 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.
