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. 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

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 is based on statutory health insurance funded by premiums and government regulation. The company leverages digital platforms for client engagement and service delivery, including e-VZP electronic communication and online branch appointment systems. Partnerships with subsidiaries like Pojišťovna VZP, a.s. and career portals enhance its ecosystem. The website's content and structure support a broad target audience including insured persons, payers, and healthcare providers. The organization demonstrates strong branding consistency and trust signals through official contact information and social media presence.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, cookie consent mechanisms, and active warnings against phishing scams. Use of Microsoft Application Insights and Google Analytics indicates ongoing monitoring and analytics. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected and should be implemented to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were found in the HTML content. Incident response and security policy pages are not explicitly found, which could be improved to enhance transparency and readiness.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to strengthen security.
  2. Publish explicit security policy and incident response information to improve transparency and trust.
  3. Regularly audit third-party scripts and libraries for vulnerabilities and update as needed.
  4. Enhance SEO by adding Open Graph and structured data metadata for better social sharing and indexing.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

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.
