Red Teaming
Red Team testing is also known as an Adversary Simulation or simply Red Teaming. During Red Team testing, highly experienced security professionals take on the guise of a real attacker and attempt to breach the organization’s cyber defenses
Red Teaming is a full scope, multi layered attack simulation designed to measure how well a company’s people and networks, applications and physical security controls can withstand an attack from a real life adversary. Red teaming helps a business remain competitive while securing its business interests by leveraging social engineering and physical, application and network penetration
