Best Breach and Attack Simulation Software 2026
Facts read 22 Sep 2026 – 15 Oct 2026
Breach and attack simulation software is used to exercise security defenses through simulated attack activity. Compare attack simulation modes and included attack surfaces to understand the breadth of exercises, then look at custom scenarios and the scenario library for ways to shape them. MITRE ATT&CK mapping, continuous scheduling and deployment model are also listed comparison points, along with the free plan and paid-from details. This ranked selection includes Keysight Eggplant Test, OpenAEV and Atomic Red Team, as well as Infection Monkey and PurpleSharp. Weigh the available approaches and operational fit against the security exercises you need to run.
