Zscaler is responsible for securing more than 400 of the Forbes Global 2000 companies. They provide security as a service delivered through a purpose-built, globally distributed platform. The focus of this lab is zero trust access utilizing a solution known as Zscaler Private Access (ZPA). ZPA is a cloud service that provides seamless, zero trust access to private applications running on public cloud or within the data center. With ZPA, applications don't need to be exposed to the internet, making them completely invisible to unauthorized users. This service enables the applications to connect to users via inside-out connectivity versus extending the network to them. It disrupts legacy approaches to remote access such as traditional VPN, establishing per-service dynamic encryption and trust evaluation.

First coined in 2019, Secure Access Service Edge (SASE) is the convergence of network and security frameworks. SASE aims to reduce the operational complexity that comes with a cloud-first delivery model. Application assurance and service optimization are achieved via global Point-of-Presence (POPs) and peering with carriers providing high-performance backbones. The combination of all these factors gives the user a consistent and secure experience no matter where they are located.
