Stratus Red Team is an open-source command-line tool for executing granular adversary-emulation techniques against live cloud environments. It is designed for security and detection-engineering teams validating threat detections in sandbox environments. Agentless simulations cover AWS, Azure, GCP, Kubernetes, Amazon EKS, and Microsoft Entra ID, with techniques mapped to MITRE ATT&CK. The software runs on Windows, macOS, and Linux, and is also available for self-hosted deployment as a self-contained Go binary, pre-built binaries, Docker image, or Homebrew installation.

Its strongest area is the depth of the simulation workflow. Stratus Red Team can warm up prerequisite infrastructure, detonate an attack technique, revert side effects, and clean up resources afterward. Terraform-managed prerequisite resources support repeatable environment preparation, while concurrent execution and correlation IDs help teams distinguish activity when multiple simulations run together. Custom attack techniques can be developed with the Go library, giving engineering teams a path beyond the included technique set.

The pricing model is open source, with no paid tier structure presented in the product details. That makes the software a focused option for teams that want granular cloud emulation without a commercial plan layer, while cloud-provider usage may incur separate infrastructure costs. Its scope is narrower than a platform centered on continuous scheduling or a broader integration layer: the emphasis is on executing and validating attack techniques. Choose Stratus Red Team when cloud coverage, ATT&CK mapping, prerequisite provisioning, and cleanup matter most. Teams seeking continuous scheduling should consider an alternative built around that workflow.

Stratus Red Team pros and cons

  • Where it wins
    • Emulates techniques across AWS, Azure, GCP, Kubernetes, and Entra ID
    • Provisions prerequisites, then reverts side effects and cleans up resources
    • Maps techniques to MITRE ATT&CK and supports concurrent execution
  • Where it doesn't
    • Focused on command-line attack emulation rather than continuous scheduling
    • Requires sandbox cloud environments and may incur provider infrastructure costs
    • Custom techniques require Go library support and engineering effort
