Atomic Red Team vs Cymulate Platform

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.

Cymulate Platform continuously validates security controls against real-world threats and provides guidance for improving defenses. Its modules include Exposure Validation, Auto Mitigation, CTEM, Detection Studio, Threat Studio, and Cymulate Cowork. Cymulate says its threat library covers MITRE ATT&CK and that new simulations for US-CERT advisories have a 24-hour SLA. Vero AI tailors threat assessments to a customer’s environment, helps prioritize findings, and supports mitigation creation. Listed partners include AWS GuardDuty, CrowdStrike, Splunk, and Anthropic Claude. The platform is designed for security operations, detection engineering, red teams, and exposure management teams, including mid-market and enterprise organizations. A free trial provides partial platform simulation for 14 days unless a quote specifies another period; pricing is on request and depends on package, assets, and scenarios. Cymulate says the platform runs on a private AWS tenant across multiple regions. It lists security certifications and compliance frameworks, protects traffic with TLS 1.2 or higher, and encrypts stored data with AES-256. Customers must provide equipment, infrastructure, servers, and third-party software or licenses required by the platform prerequisites.
