The Vanishing Security Perimeter

With the advent of growing complex on-premises and hybrid cloud environments, BYOD and IoT, the security perimeter has disappeared. Identity is the new threat vector. The emergence of evolving advanced security analytics solutions represents Borderless Behavior Analytics – a comprehensive answer to address this growing challenge. In "Borderless Behavior Analytics – Who's Inside? What're They Doing?" – now in its second edition – twelve CISO and CIO leaders share their insights on this next generation of technology evolution and the challenges behind it.

"Existing security defenses were built to protect an enterprise architecture that no longer exists."
