Atomic Red Team vs Valitrix BAS 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.

Valitrix BAS Platform is a breach and attack simulation platform that continuously checks security controls against adversary techniques mapped to MITRE ATT&CK. Its library covers 200+ techniques across all 14 tactical categories. Agent-based simulations validate endpoint, email, network, and SIEM controls, using controlled, non-destructive synthetic payloads intended to avoid damage or production interruption. Teams can configure simulation scope, target systems, timing windows, and technique categories; Enterprise customers can add exclusions and restrict testing to selected network segments or system groups. Results are mapped to MITRE ATT&CK in real-time dashboards and exportable reports. Valitrix lists evidence reporting for ISO 27001, SOC 2, NIST, and Cyber Essentials. Agents collect simulation telemetry and control-response data for reports, not underlying business data. Named SIEM validations include Splunk, Microsoft Sentinel, IBM QRadar, and Elastic, while Enterprise API access supports workflows such as Jira and ServiceNow. Basic, Professional, and Enterprise tiers vary by agents, users, attack coverage, and support. Pricing is on request, and qualified Enterprise prospects can receive a scoped proof-of-concept engagement.
