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

Nemocnice Jablonec nad Nisou, p.o. is a regional healthcare provider in the Czech Republic offering a wide range of medical services including emergency care, specialized departments such as oncology, gynecology, pediatrics, and laboratory diagnostics. The website serves patients, visitors, and healthcare professionals with comprehensive information about hospital departments, patient rights, and contact details. The hospital positions itself as a trusted regional medical institution with a medium-sized operational scale. Technically, the website is built on the Public4u CMS platform, utilizing jQuery and Google Tag Manager for analytics and user tracking. The site is served over HTTPS with a cookie consent mechanism in place, indicating a moderate level of digital maturity and compliance with privacy regulations such as GDPR. The design is professional and mobile-optimized, providing a good user experience. From a security perspective, the site enforces HTTPS and includes cookie consent but lacks explicit security headers and visible incident response contacts. No vulnerabilities or exposed sensitive data were detected in the content analysis. The absence of WHOIS registration data is a concern for domain legitimacy but does not appear to impact the operational trustworthiness of the hospital's online presence. Overall, the website is a reliable and professional digital representation of a healthcare institution, with room for improvement in security policy transparency and domain registration clarity.

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.

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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 hospital operates as a public healthcare entity serving the Jablonec nad Nisou region. Its business model focuses on providing essential medical services to the local population, supported by a structured website that facilitates patient engagement and information dissemination. The presence of e-learning and career sections indicates investment in staff development and recruitment. The hospital leverages partnerships with local service providers such as AS4U for CMS and map services. The lack of visible commercial advertising or affiliate programs aligns with its public service nature. Growth indicators include active communication of events and updates, suggesting ongoing community engagement. The hospital's market position is stable within the regional healthcare sector, with a focus on quality and patient safety.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS encryption and a cookie consent mechanism supporting GDPR compliance. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No explicit security or incident response policies are published, limiting transparency and readiness perception. The use of third-party scripts like Google Tag Manager introduces potential risk vectors that require regular auditing. No signs of vulnerabilities or exposed sensitive data were found in the HTML content. The missing WHOIS data raises questions about domain registration legitimacy but does not directly affect website security. Overall, the site is secure for general use but would benefit from enhanced security controls and policy disclosures.

Recommendations

  1. Implement and configure standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  4. Investigate and resolve the missing WHOIS registration data to enhance domain legitimacy and trust.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website uses a traditional web stack with jQuery and jQuery UI libraries, supported by the Public4u CMS platform. Google Tag Manager is integrated for analytics and marketing purposes. The site is served over HTTPS with responsive design and basic accessibility features. Performance is moderate, with no critical errors or broken elements detected. The site structure is clear with well-organized navigation menus and content sections. Opportunities exist to modernize the tech stack by reducing reliance on older JavaScript libraries and improving accessibility compliance. The hosting provider is not explicitly identified. Overall, the technical implementation supports the hospital's operational needs but could be enhanced for performance and security.
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.
