Best Breach and Attack Simulation Software in 2026
To examine how security defenses respond to simulated attacks, compare the types of exercises and attack surfaces each product covers. Attack simulation modes, custom scenarios, and scenario library size describe different ways to shape testing; MITRE ATT&CK mapping and continuous scheduling offer further comparison points. Deployment model and free-plan or paid-from details help frame operational fit. Atomic Red Team, OpenAEV, and Infection Monkey appear near the top, with PurpleSharp and BlackNoise BAS also among the early entries. Match the stated capabilities to the security exercises you need to run.
