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

CSIRT.CZ is the official National Computer Security Incident Response Team of the Czech Republic, operated by CZ.NIC under a public contract with the National Cyber and Information Security Agency. The organization provides critical cybersecurity incident response, coordination, education, and proactive security services to a broad range of stakeholders including ISPs, banks, public authorities, and academic institutions within the Czech Republic. The website reflects a professional and government-affiliated entity with strong trust indicators such as accreditation by Trusted Introducer and membership in FIRST. Technically, the site uses modern web technologies including Bootstrap and Matomo analytics, is mobile optimized, and implements a cookie consent mechanism, though it lacks explicit privacy and terms of service pages. Security posture is solid with HTTPS usage and no visible vulnerabilities, but could be improved by adding security headers and formal security policies. Overall, the domain registration data aligns well with the website's claims, showing a consistent and legitimate presence since 2007.

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

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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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

CSIRT.CZ holds a strong market position as the national cybersecurity incident response team for the Czech Republic, supported by CZ.NIC and government contracts. Its business model is focused on essential government and public sector cybersecurity services rather than commercial revenue generation. The organization targets a wide audience including ISPs, banks, public authorities, and academic institutions. The website content and linked domains indicate a well-established partnership ecosystem with national and international cybersecurity bodies. Growth indicators include active news updates and participation in global CSIRT communities. The lack of direct contact information on the homepage suggests a controlled communication channel typical for security-focused government entities.

Security posture

The security posture of the website and organization is mature, with HTTPS enforced and no exposed sensitive data. The presence of a cookie consent mechanism indicates awareness of privacy compliance, though the absence of a privacy policy and security.txt file are gaps. The site is accredited by recognized cybersecurity bodies, enhancing trust. No vulnerabilities or outdated libraries were detected in the HTML content. Recommendations include implementing additional security headers, publishing formal security and incident response policies, and improving accessibility features. Incident response readiness is implied but not explicitly detailed on the site.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information for incident reporting and data protection officer to enhance trust and compliance.
  5. Enhance accessibility features and SEO optimization to improve user experience and reach.

Technical notes

Notes

The website is built on a modern tech stack including Bootstrap for responsive design, Matomo for analytics, and likely Aldryn CMS (Django-based) for content management. The site loads external CSS and JavaScript efficiently and includes a cookie consent mechanism. Performance is moderate with good mobile optimization. No broken elements or errors were detected in the HTML content. Hosting appears to be managed by CZ.NIC, ensuring reliable infrastructure. Opportunities exist to improve technical SEO and accessibility compliance. No technical debt or legacy technology was observed.
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.
