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

Centrum pro zjišťování výsledků vzdělávání (CZVV) is a Czech governmental organization responsible for conducting and managing nationwide educational assessments, including maturita exams, unified entrance exams, and final exams. The website serves as an official portal providing information and resources for students, schools, and educational authorities. It maintains a strong market position as an authoritative entity in the Czech education sector, offering key services related to educational testing and data analysis. Technically, the website is built on Joomla CMS with common web technologies such as jQuery, Bootstrap, and FontAwesome. It integrates Google Custom Search Engine for site search functionality. The site is mobile-optimized with a moderate performance profile and basic accessibility features. The presence of cookie consent and privacy policy indicates attention to privacy compliance. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms but lacks visible advanced security headers. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data is unavailable, which is typical for government domains, but the domain's .gov.cz TLD and consistent content strongly support legitimacy. Overall, the website is professional, trustworthy, and well-suited for its governmental educational purpose. Strategic improvements in security headers and explicit security policies could enhance its security posture further.

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

8 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

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

CZVV operates as a government entity focused on educational assessment in the Czech Republic. Its competitive advantage lies in its official mandate and integration with the Ministry of Education and related institutions. The business model is service-oriented, providing standardized testing and data analysis to schools and government bodies. Revenue streams are likely government-funded. The target customers include students, schools, and educational administrators. The partnership ecosystem includes the Ministry of Education (msmt.cz) and the National Pedagogical Institute (npi.cz). Growth indicators are stable given the governmental nature. The website supports transparency and communication with stakeholders through news updates and contact information.

Security posture

The security maturity level is moderate. HTTPS is enforced, and cookie consent is implemented, supporting privacy compliance. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests room for improvement. No incident response or security policy documentation is publicly available. No vulnerabilities or exposed sensitive data were found in the analysis. The site uses standard third-party libraries, which should be regularly audited. GDPR compliance is indicated by privacy and cookie policies. Overall, the security posture is adequate for a government informational site but could benefit from enhanced security controls and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  4. Enhance accessibility features to meet higher standards for users with disabilities.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses Joomla CMS with a standard technology stack including jQuery, Bootstrap, and FontAwesome. Google Custom Search Engine is integrated for search functionality. The site is mobile responsive and has a moderate performance profile. There is no evidence of advanced hosting or CDN services. The HTML and CSS appear valid with no major errors. Accessibility is basic but present. SEO optimization is basic with meta tags and keywords included. The site could improve by adopting modern frontend frameworks and enhancing performance optimization techniques.
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.
