CyberRangeCZ is an open-source platform for building, delivering, and managing advanced cybersecurity training environments.
It enables organizations to create interactive, scenario-based cyber exercises with features like:

• Dynamic sandbox provisioning
• Real-time feedback
• Centralized user management

Designed for scalability and automation, the platform supports both individual and group-based training across diverse environments, making it suitable for educational, governmental, and enterprise use cases.

CyberRangeCZ is built to support realistic, automated training simulations designed to:

• Help teams build real skills with hands-on, cloud-based training environments.
• Make it easy to reuse and tweak scenarios with clear, modular setup configurations.
• Manage large-scale training for trainees with minimal manual overhead.

The CyberRangeCZ Platform is a container-based, microservices architecture optimized for creating and running cyber-range exercises:

• Supports OpenStack and AWS cloud back-ends.
• Offers linear (fixed-level) training model.
• Configured with an infrastructure-as-code model.

CyberRangeCZ is built atop a modern microservice ecosystem:

• Sandbox Service – Manages lifecycle of emulated environments.
• Training Service – Delivers linear (fixed-level) training definitions and execution.
• Supporting Services – Answers Storage, OpenSearch-backed event logging, MITRE Technique, User & Group, OIDC provider, etc.

Workload infrastructure on Kubernetes and OpenStack/AWS enables flexible deployment and sandbox provisioning.

• Serves as the primary tool for deploying the entire CyberRangeCZ platform onto Kubernetes clusters using Helm.
• Includes:
  • Helm configuration files (helm/)
  • Sandbox training definitions (training-definitions/)
  • Complete automated deployment workflows, including a Vagrant-based proof-of-concept setup
• Acts as the hub for configuring platform services, training definitions, proxy jump access, networking, and demo environments.

• tf-module-helm – Terraform modules integrating with Helm deployment pipelines.
• devops-tf-deployment – Manages provisioning of cloud infrastructure on OpenStack and AWS using Terraform (via OpenTofu), feeding into the Helm deployment process for full platform installation.
• backend-sandbox-service – Provides APIs for sandbox orchestration and lifecycle management.
• backend-training, backend-answers-storage – Java-based microservices powering training logic, assistance, and feedback capture.
• frontend-platform – The Angular-based web interface for launching training exercises and reviewing progress.
