Atomic Red Team is an open-source library of tests that security teams can use to simulate adversarial activity in their environments.


Atomic tests run in five minutes or less and require minimal setup. Spend less time configuring and more time testing!


Security teams don’t want to operate with a “hopes and prayers” attitude towards detection. Atomic tests are mapped to the MITRE ATT&CK matrix, so you always know which techniques you do and don’t detect.


Atomic Red Team is open source and community developed. By working together, we can develop a fuller picture of the security landscape.
