Today’s IT teams face a common challenge: how to securely enable the growing universe of roaming users, devices, and software as a service (SaaS) apps without adding complexity or reducing end-user performance — all while leveraging their existing security investments.

This book examines the changing network and security landscape, gaps in the existing security stack, and the steps you can take to keep your organization safe and secure as your network evolves. These changes are paving the way to a new solution category that delivers multiple security functions from the cloud that are simple, scalable, and flexible to meet the unique needs of your business and its changing network architecture.
