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

The website finfoveskole.gov.cz is an official Czech government educational portal dedicated to supporting financial literacy and tax education for students and teachers. It is a collaborative project between the Financial Administration and Customs Administration of the Czech Republic, providing comprehensive information and resources related to taxes and customs. The site is well-structured, professionally designed, and targets primarily educational institutions and individuals seeking knowledge in financial matters. The presence of official government domains and partner links reinforces its legitimacy and authoritative position in the market. From a technical perspective, the website employs modern web technologies including HTML5, CSS3, JavaScript, Google Fonts, and integrates Cookiebot for cookie consent management and Matomo for privacy-conscious analytics. The site is mobile optimized, accessible, and demonstrates good SEO practices. However, there is no detected CMS or explicit hosting provider information. Performance is moderate, with room for optimization. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers and explicit security or incident response policies publicly available suggests areas for improvement. The lack of WHOIS data is notable but likely due to registry policies for government domains rather than malicious intent. Overall, the website presents a low-risk profile with strong business credibility and privacy compliance. Strategic recommendations include enhancing security headers, publishing incident response and vulnerability disclosure policies, and improving transparency around contact information for security matters.

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

5 findings rated critical or high. Fix these first.

  1. 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

      Prevents clickjacking attacks

      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';…

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Finfoveskole.gov.cz operates as a government educational platform under the Czech Ministry of Finance, focusing on financial literacy and tax education. Its market positioning is that of an authoritative source for students and educators, leveraging partnerships with key government agencies such as the Financial Administration and Customs Administration. The business model is non-commercial, aimed at public education and awareness. Revenue streams are not applicable, but the site supports government initiatives to improve tax compliance and financial knowledge. The target customer segments include secondary schools, teachers, and students. Growth indicators include ongoing content updates and integration with other government digital services. The partnership ecosystem is strong with official government domains and social media presence. The site maintains consistent branding and content quality aligned with government standards.

Security posture

The security maturity of finfoveskole.gov.cz is moderate to good. HTTPS is properly implemented, ensuring encrypted communication. Cookie consent is managed via Cookiebot, providing transparency and user control over cookies. The site uses session cookies for state management and integrates Matomo analytics, which respects user privacy. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No explicit security or incident response policies are published, and no security.txt file is present, limiting vulnerability disclosure transparency. No vulnerabilities or exposed sensitive data were detected in the content. Incident response readiness and security culture indicators are not publicly visible, suggesting an opportunity to enhance trust and preparedness. Overall, the site is secure for its purpose but could benefit from additional security best practices and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve communication with security researchers.
  4. Enhance contact information availability for security incidents, including dedicated security or abuse email addresses.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used and maintain up-to-date components.

Technical notes

Notes

The website is built using standard web technologies such as HTML5, CSS3, and JavaScript, with external resources including Google Fonts and Cookiebot scripts. It integrates Matomo analytics for user tracking, favoring privacy over commercial analytics platforms. The site is mobile responsive and includes accessibility features such as ARIA roles and skip links. No CMS or backend platform is explicitly detected, suggesting a custom or government-managed infrastructure. Performance is moderate, with potential for optimization in loading times and resource management. The site uses HTTPS but lacks some advanced security headers. The technical stack is modern and appropriate for an official government educational site, but there is room for improvement in security hardening and performance tuning.
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.
