Zscaler Secure Access Service Edge (SASE)

Status quo is inhibiting digital business

For the last 30 years, networks have been connecting users to applications in the data center, which was surrounded by a secure perimeter to keep apps and data safe from the outside. But with applications moving to the cloud, IoT becoming more common, and users connecting from everywhere, network security is no longer able to solve the fundamental challenge of security and is instead adding significant complexity and cost.
