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.

Each enterprise needs to perform this task in their own way. The ZPA administrator needs to coordinate the discovery of all the applications that need to be migrated to ZPA.

First, obtain the list of applications that need to be migrated to ZPA. A standard questionnaire can be developed per the enterprise guidelines, and all the collected data needs to be classified accordingly.

The next step is to create application segments and then add the necessary segment groups and server groups. The application connectors could reside in on-premises data centers or in public cloud environments such as AWS and Azure.

The final step is to map the end user access to these applications. Remember that users are denied ZPA access to every private application by default and...
