"Executive summary

 As applications continue to migrate to the cloud, changing traffic patterns drive the need for a new Wide Area Network (WAN) approach and security model. When all applications resided in enterprise data centers, life was simpler for IT; all traffic from the branch was backhauled to the data center over MPLS circuits, with the entire stack of security services enforced at data center egress points, requiring only fundamental security services at the branch. Now, applications reside everywhere and may be hosted in the data center, in public and private clouds, or delivered by myriad Software-as-a-Service (SaaS) providers. To further complicate the security model and the IT challenge, users now access applications from anywhere, from any device and across diverse WAN transports, including the internet. This increases the attack surface, significantly increasing the need for more advanced security services to protect the branch from threats. While enterprises could deploy next-generation firewalls at every branch, that model is untenable. The hardware is too expensive, and managing dedicated security appliances at hundreds or thousands of branch locations requires far too many IT resources. In addition, branch locations need advanced security controls, like sandboxing, intrusion prevention (IPS) and Data Loss Prevention, as well as SSL inspection,  to protect against advanced threats. To address the security and cost challenges, centrally orchestrated cloud-hosted security services, such as those available from Zscaler™, have emerged and are experiencing hyper-growth. The Zscaler Cloud Security Platform combined with the application-aware, business-driven Silver Peak® Unity EdgeConnect™ SD-WAN edge platform provides a powerful solution that secures the enterprise from threats delivers the highest application performance and user experience and keeps costs in check."
