Diving into Secure Access Service Edge

By: Jeremiah

Overview of this book

The SASE concept was coined by Gartner after seeing a pattern emerge in cloud and SD-WAN projects where full security integration was needed. The market behavior lately has sparked something like a "space race" for all technology manufacturers and cloud service providers to offer a "SASE" solution. The current training available in the market is minimal and manufacturer-oriented, with new services being released every few weeks. Professional architects and engineers trying to implement SASE need to take a manufacturer-neutral approach. This guide provides a foundation for understanding SASE, but it also has a lasting impact because it not only addresses the problems that existed at the time of publication, but also provides a continual learning approach to successfully lead in a market that evolves every few weeks. Technology teams need a tool that provides a model to keep up with new information as it becomes available and stay ahead of market hype. With this book, you’ll learn about crucial models for SASE success in designing, building, deploying, and supporting operations to ensure the most positive user experience (UX). In addition to SASE, you’ll gain insight into SD-WAN design, DevOps, zero trust, and next-generation technical education methods.

SASE SD-WAN

Secure Access Service Edge (SASE) and SD-WAN are two technologies that appear similar on the surface and may seem to overlap in the market. It is possible to buy either solution separately, successfully operating one service or the other. However, for secure network communications, almost every organization will operate both SD-WAN and SASE as an integrated and interdependent secure platform.

In this chapter, we will provide an understanding of what SD-WAN is, why to use SD-WAN, how to use SD-WAN, when to use SD-WAN, and what SD-WAN looks like when integrated with SASE.

We will cover the following topics in this chapter:

  • SD-What – understand what SD-WAN is
  • SD-Why – understand why to use SD-WAN
  • SD-How – understand how to use SD-WAN
  • SD-When – understand when to use SD-WAN
  • SD-SASE – understand what SD-WAN integrated with SASE looks like
