Breach and Attack Simulation FAQs

What is Breach and Attack Simulation (BAS) and how can it protect my business?
Breach and Attack Simulation (BAS) is a proactive security testing technique that simulates real-world attacks to assess security posture. BAS identifies vulnerabilities, evaluates security controls and provides realistic attack simulations. It supports continuous monitoring, mitigates risks, helps meet compliance requirements and enhances incident response. By proactively identifying weaknesses and improving defences against evolving threats, BAS enhances overall security.
