Atomic Red Team vs ShadowBreach

Atomic Red Team is a free library of tests security teams can run to check controls, validate visibility, and assess detection coverage. Its tests emulate adversary behaviors and map to the MITRE ATT&CK matrix. They have few dependencies and use a structured format suited to automation frameworks. Invoke-AtomicRedTeam is a PowerShell module for testing defenses against attack techniques; it can run tests locally or on remote machines through PowerShell Remoting. Atomic Runner can run a configurable list unattended, once per week by default. The project includes a Ruby API to validate tests and generate documentation, and pulls ATT&CK data in STIX form. Listed integrations include Microsoft Defender for Endpoint, AttackIQ, Datadog Workload Security Evaluator, OpenBAS, Splunk Attack Range, and Tidal Cyber. Coverage includes Windows, Linux, macOS, cloud infrastructure, containers, SaaS, Azure AD, Google Workspace, Office 365, and IaaS providers. Tests can be chained manually, but there is no automated solution for emulating a specific attack group as a whole. Users are instructed to obtain permission from the environment owner before running a test.

ShadowBreach is an AI-enabled cyber operations platform from Markon Solutions for planning, executing, and documenting attack activity within a local environment. It is designed for red team operations, exercise red cells, and repeatable test and evaluation. The platform parses threat and vulnerability data for continuous testing and self-service red team work. Operators set escalation thresholds, while the system records the reasoning behind actions and maintains a decision trail during an engagement. Its adversary emulation adapts tactics when defensive actions change. Teams can rerun standardized test packs against new builds, schedule testing continuously, and scale scenarios across training audiences. Framework-mapped reporting is generated during operations to reduce manual documentation while retaining operator authority. Markon is headquartered in Falls Church, Virginia, United States. ShadowBreach is paid with pricing on request; Markon invites prospective users to contact its team and request a product demo. No third-party integrations, certification, compliance standard, or support terms are listed.
