MITRE Caldera

MITRE Caldera is an open-source platform for automating adversary emulation and red team operations. It enables operators to model adversary behavior using plugins and techniques, execute operation plans, and evaluate defensive controls. Caldera's architecture supports integration with MITRE ATT&CK mappings and other telemetry sources to measure detection coverage. The platform can orchestrate chains of actions across managed agents to simulate complex campaigns. It is used by defenders to validate detection and response capabilities and by researchers to prototype new adversary behaviors.
