The Executive Guide to Zero Trust delivers unique and much-needed insight into how a Zero Trust （ZT） strategy shifts the focus of cybersecurity from “hardening the perimeter” to protecting an enterprise’s most critical assets。 The book defines a path that enables cyber leaders to align diverse initiatives， investments， and operational groups in support of a strategy that offers greatly enhanced defense against the unrelating advance of cyber threats while also embedding alignment principles that increase the CISO’s ability to demonstrate the value of cybersecurity to business executives throughout the organization。 The Executive Guide to Zero Trust is based on input from leading CISOs and industry experts who understand the ZT journey: defining business and technical objectives， winning internal support and executive endorsement， establishing a holistic “path to ZT” that identifies critical milestones in planning， rollout， and refinement， and connecting this vision to the technologies and team members that translate cyber strategy into cyber defense。
