Cloud Range Cyber Attack Simulations is a live-fire cyber range platform that enables security teams to practice detecting, responding to, and containing cyber incidents in a controlled environment. The platform offers both preconfigured and custom simulation exercises across varying difficulty levels — novice, intermediate, and advanced. Simulations are built on actual threat intelligence and mapped to the MITRE ATT&CK framework, covering specific APTs and threat actors using their known tactics, techniques, and procedures (TTPs). Attack scenarios include ransomware, phishing, DNS tunneling, OT/ICS PLC attacks, supply chain attacks, nation-state threats, AI-driven threats, and more. The platform supports multiple team formats including blue team, red team, red vs. blue, and purple team exercises. Attacks can be executed via automated command and control (C2) devices, interactive on-net operations with representative threat actors, or a combination of both. Traffic generation realism is a feature of the platform, with traffic configurable by direction (inbound/outbound), type (protocol), frequency, and content to simulate enterprise network conditions. The environment includes a full IT/OT/cloud network with infrastructure and security applications. Individual skills development is available through FlexLabs SkillsPaks modules. Participants earn CPE certificates accepted by ISC2, CompTIA, and EC-Council upon completing exercises.
