Deploy Breach and Attack Simulation tools to continuously validate security control effectiveness by safely emulating real-world attack techniques across the kill chain.
Breach and Attack Simulation (BAS) is an automated, continuous approach to validating security control effectiveness by safely executing real-world attack techniques against production security infrastructure. Unlike traditional penetration testing (point-in-time), BAS platforms continuously simulate threats mapped to MITRE ATT&CK, testing endpoint protection, network security, email gateways, SIEM detection, and incident response capabilities. Leading platforms include SafeBreach, AttackIQ, Picus Security (2024 Gartner Customers' Choice), Cymulate, Pentera, and SCYTHE. BAS 2.0 solutions safely emulate real attacker behavior across the entire IT environment without requiring pre-deployed agents on every endpoint.

Control Effectiveness = (Attacks Prevented + Attacks Detected) / Total Attacks Simulated * 100
Example:
Total simulations: 500
Prevented (blocked): 350
Detected (alerted): 100
Missed (no action): 50
Prevention Rate: 350/500 = 70%
Detection Rate: 100/500 = 20%
Overall Score: 450/500 = 90%
Gap Rate: 50/500 = 10%
