By: Ravi Devarasetty

Overview of this book

Many organizations are moving away from on-premises solutions to simplify administration and reduce expensive hardware upgrades. This book uses real-world examples of deployments to help you explore Zscaler, an information security platform that offers cloud-based security for both web traffic and private enterprise applications. You'll start by understanding how Zscaler was born in the cloud, how it evolved into a mature product, and how it continues to do so with the addition of sophisticated features that are necessary to stay ahead in today's corporate environment. The book then covers Zscaler Internet Access and Zscaler Private Access architectures in detail, before moving on to show you how to map future security requirements to ZIA features and transition your business applications to ZPA. As you make progress, you'll get to grips with all the essential features needed to architect a customized security solution and support it. Finally, you'll find out how to troubleshoot the newly implemented ZIA and ZPA solutions and make them work efficiently for your enterprise. By the end of this Zscaler book, you'll have developed the skills to design, deploy, implement, and support a customized Zscaler security solution.

The customer would like to know what kind of data is flowing through their enterprise systems, such as which internet applications are being used, which locations are using the most bandwidth, and if that bandwidth is being spent on productive applications supporting the company's bottom line.

From a Zscaler perspective, it gives information about where the threats are coming from and what types of threats are evolving, and helps Zscaler plan for future growth by adding more capacity to its cloud locations. Of course, it can also be used for advertising and marketing purposes.
