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

The website mzp.gov.cz is the official online presence of the Czech Ministry of the Environment, providing comprehensive information and services related to environmental protection, sustainable development, and public administration. It serves a broad audience including the general public, government officials, media, and stakeholders interested in environmental issues. The site is well-structured with clear navigation, rich content, and multiple communication channels including social media and newsletters. Technically, the site is built on Drupal 10, leveraging modern web technologies such as Bootstrap for responsive design and Piwik PRO for analytics. The site demonstrates good mobile optimization, accessibility, and SEO practices. Security is robust with HTTPS enforced and standard security headers present. Cookie consent mechanisms and privacy policies are implemented in compliance with GDPR. The security posture is strong with no visible vulnerabilities or exposed sensitive data. However, the absence of publicly available WHOIS data limits transparency, though this is common for government domains. Overall, the site is trustworthy, professional, and secure, fulfilling its role as a government information portal effectively. Strategic recommendations include publishing explicit security policies and incident response information, adding a security.txt file for vulnerability disclosures, and maintaining regular audits of third-party scripts to ensure ongoing security 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

4 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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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 384-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

The Ministry of the Environment operates as a key government entity in the Czech Republic, focusing on environmental governance, policy implementation, and public engagement. Its market position is authoritative within the government sector, providing regulatory oversight, funding programs, and public information. The business model is non-commercial, centered on public service and regulatory functions. The ministry maintains partnerships with various national environmental agencies and international organizations, as reflected in linked partner domains. Growth indicators are not applicable, but the site reflects ongoing updates and active communication. The ministry's digital presence supports transparency, citizen engagement, and policy dissemination effectively.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive cookie consent, and privacy compliance aligned with GDPR. Security headers such as HSTS, X-Frame-Options, and Content-Security-Policy are present, enhancing protection against common web threats. No exposed credentials or sensitive data were detected in the HTML content. The use of Piwik PRO analytics is privacy-conscious. However, the lack of a public security policy or incident response page and absence of a security.txt file represent gaps in transparency and vulnerability management. Overall, the site is secure but could improve in formalizing and publishing security governance documentation.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide public contact information for the Data Protection Officer or security team.
  4. Regularly review and update third-party scripts and analytics tools to mitigate risks.
  5. Enhance monitoring and logging to detect and respond to security incidents promptly.

Technical notes

Notes

The site is built on Drupal 10, a modern and widely supported CMS, ensuring maintainability and security updates. It uses Bootstrap for responsive design and Slick Carousel for interactive elements, providing a good user experience across devices. Piwik PRO is integrated for analytics, supporting privacy-compliant data collection. The site loads scripts asynchronously and defers non-critical JavaScript, optimizing performance. Accessibility features such as skip links and ARIA roles are implemented. SEO is supported by canonical links, meta tags, and structured navigation. Hosting details are not explicitly available, but the site uses HTTPS with strong SSL configuration. Overall, the technical infrastructure is solid, with opportunities to enhance hosting transparency and security documentation.
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.
