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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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.

Add-on

Leaked records that mention onconet.cz, from OffSeq Breach.

No leaked records found

Breach holds no records for onconet.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The portal occupies a niche position as a government and academic-backed resource for oncology care in the Czech Republic. Its competitive advantage lies in authoritative data, official support, and integration with national health programs. The business model is non-commercial, funded by academic grants and government projects, focusing on public health impact rather than revenue. Key partnerships include the Ministry of Health, Astra Zeneca (grant support), and various Czech health registries. The portal's growth is indicated by recent updates and pilot releases. The target audience includes patients, clinicians, and policy makers. Strategic observations highlight the importance of maintaining data accuracy, expanding user engagement, and enhancing compliance with privacy and security standards.

Security posture

The website demonstrates a baseline security posture with HTTPS and cookie consent mechanisms. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No vulnerability disclosure or incident response contacts are provided, which could hinder timely reporting and remediation of security issues. The absence of a privacy policy and terms of service reduces transparency regarding data handling and user rights, potentially impacting GDPR compliance. The use of Google Analytics introduces moderate user tracking, but no detailed data retention or privacy compliance statements are visible. Overall, the security maturity is moderate but could be improved by adopting best practices in headers, policies, and incident response readiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and GDPR compliance.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file and provide clear contact channels for vulnerability reporting and incident response.
  4. Enhance SSL/TLS configuration and regularly audit third-party scripts for vulnerabilities.
  5. Increase visibility of official contact information to improve user trust and support.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, JavaScript, and Leaflet.js for interactive maps. Google Tag Manager is used for analytics and tracking. The site is mobile responsive and includes accessibility navigation links. Performance is moderate with external dependencies on CDN-hosted libraries. No CMS or hosting provider details are explicitly detected. The site structure is clear with semantic HTML and meta tags supporting SEO. Technical risks include lack of visible security headers and absence of formal privacy and security documentation. Opportunities exist to modernize security practices and improve compliance documentation to reduce technical debt and enhance user trust.
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.
