RedTeamSimmer is an open-source, web based adversary emulation platform providing a modern UI for orchestrating Atomic Red Team tests across enterprise Windows environments. It was initially created for Purple Team exercises but has evolved into a comprehensive adversary simulation tool.

The platform enables security teams to execute MITRE ATT&CK-aligned test cases, manage test orchestration across multiple endpoints, and validate detection capabilities in a controlled manner. It streamlines the workflow between red and blue teams by providing a centralized interface for planning, executing, and reporting on adversary emulation exercises.
