Ústav zdravotnických informací a statistiky ČR · Healthcare · Czech Republic
Medium risk. 6 critical or high findings in Email security, Security headers and 2 other checks.
The website www.prevenceproplice.cz represents a Czech national public health program focused on early detection and prevention of lung cancer. Operated by the Ústav zdravotnických informací a statistiky ČR (Institute of Health Information and Statistics of the Czech Republic), it provides comprehensive information, screening services, and support for smoking cessation. The site is well-positioned within the healthcare sector in the Czech Republic, supported by government and professional medical societies, indicating a strong market position in public health screening programs. Technically, the website employs modern web technologies including the Foundation CSS framework and Matomo analytics for privacy-conscious user tracking. It is mobile-optimized, accessible, and SEO-friendly, with embedded multimedia content enhancing user engagement. The site uses HTTPS and secure forms but lacks some advanced security headers and explicit security policies. From a security perspective, the site demonstrates good baseline practices such as HTTPS enforcement and cookie consent mechanisms. However, the absence of WHOIS data and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or suspicious content were detected, and the site maintains a high trust level through official institutional branding and transparent privacy practices. Overall, the website is a credible and professional resource for lung cancer screening in the Czech Republic, with recommendations to enhance security headers, publish incident response contacts, and improve WHOIS transparency to further strengthen trust and compliance.
Scanned
NIS2 Art. 21(2)
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.

Each check with its score, findings and the evidence it collected.
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.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
