What is Breach and Attack Simulation (BAS)?

Breach and Attack Simulation BAS continuously emulates real attacker TTPs to validate that security controls detect and block threats, exposing coverage gaps.

Understanding Breach and Attack Simulation (BAS)

Breach and Attack Simulation BAS is a category of security tooling that continuously and automatically emulates real-world adversary tactics, techniques, and procedures against an organization's environment. By safely launching simulated phishing, lateral movement, exfiltration, and other attack steps, BAS validates whether existing controls such as EDR, firewalls, and SIEM actually detect and block them. The results help teams identify coverage gaps and measure security posture against frameworks like MITRE ATTACK.
