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

The website www.irz.cz serves as the official portal for the Integrovaný registr znečišťování (IRZ), an integrated pollution register managed by the Czech Ministry of the Environment (Ministerstvo životního prostředí) in partnership with CENIA. It provides public access to environmental data concerning pollutant emissions and transfers reported by thousands of facilities across the Czech Republic. The site targets both the general public and reporting entities, offering search tools, documentation, and regulatory information. The business model is a government-operated public information service with a medium organizational size and a history dating back to 2004. Technically, the site is built on Drupal 10 CMS with modern web technologies including Bootstrap and jQuery. It features responsive design, accessibility considerations, and good SEO practices. Performance is moderate, with a well-structured navigation and professional design. Security posture is strong with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and incident response disclosures are lacking. No vulnerabilities or exposed sensitive data were detected. From a security and compliance perspective, the site demonstrates GDPR compliance with clear privacy and cookie policies. However, the absence of WHOIS data for the domain reduces trust from a domain registration standpoint, though the official branding and content strongly support legitimacy. No terms of service or vulnerability disclosure policies are published. Contact information is limited to a general info email address. Overall, the site is a trustworthy and professional government resource with good technical and security practices. Strategic improvements include publishing security policies, incident response contacts, and enhancing domain registration transparency to 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

6 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

    • High

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 IRZ website occupies a critical niche as the official environmental data repository for the Czech Republic, operated by the Ministry of Environment. Its competitive advantage lies in authoritative data provision, regulatory backing, and integration with other government environmental systems like ISPOP and CENIA. The business model is non-commercial, focused on public service and regulatory compliance. Revenue streams are government-funded. Target customers include environmental professionals, regulatory bodies, and the general public interested in pollution data. Growth indicators include ongoing updates and expansion of data sets. The partnership ecosystem includes CENIA, ISPOP, and other government portals. Strategic observations highlight the importance of maintaining data accuracy, transparency, and expanding user engagement through improved search and open data initiatives.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a cookie consent mechanism aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were found in the HTML content. However, the lack of explicit security headers such as Content-Security-Policy and absence of a published security policy or incident response plan represent compliance gaps. The missing WHOIS data for the domain is a concern for domain legitimacy verification. There is no visible vulnerability disclosure program or security.txt file. Overall, the site is secure for public use but would benefit from enhanced transparency and formal security documentation to meet best practices and regulatory expectations.

Recommendations

  1. Publish explicit security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  2. Create and publish a security.txt file to facilitate vulnerability reporting and incident response.
  3. Add a dedicated security policy and incident response information page to improve transparency.
  4. Investigate and resolve the missing WHOIS data to improve domain registration trustworthiness.
  5. Consider publishing terms of service to clarify user rights and responsibilities.

Technical notes

Notes

The website is built on Drupal 10 CMS, leveraging Bootstrap for responsive design and jQuery for interactivity. It uses Slick Carousel for image sliders and includes accessibility features such as skip links and ARIA labels. The site is mobile-optimized and SEO-friendly with proper meta tags and canonical links. Performance is moderate, with no broken elements detected. The technical stack is modern and well-maintained, though opportunities exist to enhance security headers and implement advanced performance optimizations. Hosting provider details are not disclosed in the HTML content. Overall, the technical infrastructure supports a stable and user-friendly experience.
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.
