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

Všeobecná zdravotní pojišťovna ČR (VZP ČR) is the largest public health insurance provider in the Czech Republic, serving insured persons, payers, and healthcare providers. The website offers comprehensive information and services including electronic communication platforms, client support, and insurance product offerings. The company maintains a strong market position as a government-related essential healthcare entity with a large client base. Technically, the website is built on a modern infrastructure leveraging Microsoft Azure services, Application Insights, and Google Tag Manager, ensuring good performance, mobile optimization, and accessibility. Security posture is strong with HTTPS enforcement, consent-based tracking, and no visible vulnerabilities, although explicit security policies and vulnerability disclosure mechanisms are not publicly documented. Overall, the site demonstrates high professionalism, trustworthiness, and compliance with privacy regulations such as GDPR. The lack of WHOIS data is likely due to privacy protection but does not detract from the legitimacy of the site given the official branding and contact information.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 20 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

VZP ČR operates in the healthcare and government sectors, providing essential health insurance services. Its business model focuses on public health insurance coverage, electronic client services, and partnerships with healthcare providers. The company leverages subsidiary entities such as Pojišťovna VZP, a.s. for insurance product diversification. The website's content and linked domains indicate a well-established partnership ecosystem including humanitarian aid and career portals. The company targets insured individuals, payers, and healthcare professionals primarily within the Czech Republic. Growth indicators include active campaigns, digital service offerings, and extensive client support. The company maintains a strong brand presence and trust signals through official contact details and social media engagement.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of security-focused cookies and consent mechanisms, and integration of telemetry tools with privacy considerations. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a publicly available security policy, incident response contacts, or vulnerability disclosure program represents an area for improvement. The site follows best practices in cookie consent and tracking transparency, aligning with GDPR requirements. Overall, the security maturity is good but could be enhanced by publishing explicit security governance documents and establishing formal incident response channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and incident response procedures.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance HTTP security headers explicitly, including Content-Security-Policy and X-Content-Type-Options.
  4. Maintain transparency on data retention policies related to analytics and tracking cookies.
  5. Continue monitoring and updating third-party libraries and tracking tools to mitigate emerging vulnerabilities.

Technical notes

Notes

The website is hosted likely on Microsoft Azure infrastructure, indicated by ARRAffinity cookies and Microsoft Application Insights usage. It uses modern JavaScript libraries and tracking tools such as Google Tag Manager and Microsoft Clarity. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate with efficient asset loading from a dedicated CDN. The site lacks explicit CMS identification but uses custom front-end assets. SEO is well addressed with meta tags and structured navigation. Technical risks are minimal, but continuous monitoring of third-party scripts and consent mechanisms is recommended to maintain compliance 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.
