Zscaler Secure Access Service Edge (SASE)

Status quo is inhibiting digital business

For the last few decades, 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. Today, with applications moving to the cloud, internet of things (IoT) devices becoming more common, and users connecting from everywhere, network security can no longer solve the fundamental challenge of security. Instead, it's piling on complexity and costs.

The new reality

More applications live outside the data center

SASE: The architecture for a cloud and mobile world

The secure access service edge (SASE) is a model defined by Gartner specifically to address the security challenges of the new reality facing today's organizations.

“The secure access service edge is an emerging offering combining comprehensive WAN capabilities with comprehensive network security functions (such as SWG, CASB, FWaaS, and ZTNA) to support the dynamic secure access needs of digital enterprises.” – Gartner

The Zscaler Zero Trust Exchange™ is a SASE service built from the ground up for performance and scalability. As a globally distributed platform, it ensures users are always a short hop from their applications. Through peering with hundreds of partners in major internet exchanges around the world, it offers optimal performance and reliability for your users.
