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

Centrum pro zjišťování výsledků vzdělávání (CZVV) is a Czech governmental organization responsible for conducting national educational assessments including maturita exams, unified entrance exams, and final exams. The website serves as an official portal providing information, schedules, and data analytics related to these educational evaluations. It targets students, schools, and educational authorities within the Czech Republic. The organization holds a strong market position as the official body for educational testing in the country. Technically, the website is built on Joomla CMS with common frontend technologies such as jQuery, Bootstrap, and FontAwesome. It includes a cookie consent mechanism and privacy policy, indicating awareness of GDPR compliance. The site is mobile responsive and offers a clear navigation structure, though accessibility features are basic. Performance is moderate with no critical technical issues detected. From a security perspective, the site enforces HTTPS and implements cookie consent but lacks visible security headers and explicit security policies. No vulnerabilities or exposed sensitive data were identified in the provided content. WHOIS data is unavailable, likely due to the .gov.cz domain registry policies, but the domain's legitimacy is supported by official content and government affiliations. Overall, the website presents a professional and trustworthy front for the CZVV organization, with room for improvement in security headers, accessibility, and explicit security disclosures. The risk level is low given the official nature and content focus, but enhancing security posture and transparency would further strengthen trust and compliance.

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 services in the Czech Republic. Its business model revolves around providing standardized testing and evaluation services mandated by the Ministry of Education. The organization benefits from strong government partnerships, including direct links to the Ministry of Education and the National Pedagogical Institute. Revenue streams are likely government-funded, with no commercial advertising or affiliate programs detected. The target customers are educational institutions, students, and policymakers. The website's content and structure support transparency and accessibility of information, reinforcing CZVV's authoritative role in the education sector. Growth indicators include ongoing updates to exam schedules and data analytics offerings. The partnership ecosystem is limited to official government bodies, reflecting the organization's public sector nature.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism in place, supporting GDPR compliance. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the overall security posture. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The site does not expose sensitive data or show signs of vulnerable libraries in the analyzed content. Incident response readiness and security culture indicators are not evident from the public content. To improve, CZVV should implement recommended security headers, publish security policies, and consider a vulnerability disclosure program to enhance transparency and trust.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish explicit security and incident response policies on the website.
  3. Establish and publicize a vulnerability disclosure program, including a security.txt file.
  4. Enhance website accessibility to meet WCAG standards more fully.
  5. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.

Technical notes

Notes

The website uses Joomla CMS with a frontend stack including jQuery, Bootstrap, and FontAwesome, which are widely supported but require regular updates to avoid vulnerabilities. The site is mobile responsive and includes a cookie consent mechanism, indicating attention to privacy compliance. Performance is moderate, with no critical errors or broken elements detected. SEO optimization is basic, with meta tags present but no advanced structured data or Open Graph tags found. Accessibility features are minimal but present. Hosting provider details are not disclosed. The lack of security headers and limited technical security controls represent areas for modernization and risk reduction.
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.
