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. Likewise, users in remote and branch offices need the same level of network performance and security as users in central locations. IT must develop strategies to protect users — wherever they work and on any device they use  — from a variety of threats, including malware infections, command-and-control callbacks, phishing attacks, unauthorized access, and unacceptable use, among others.
