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 shows promise of persistence in the market as terminology technology practitioners will potentially use for secure communications in the same way that “Wi-Fi” has persisted with IEEE 802.11. Neither term was a technical contribution to a standard but was once coined as a marketing term and adopted to simplify the discussion of related topics. SASE may be as generic of a term for secure communications as Internet of Things (IoT) has become for device-to-device communications.

Security Service Edge (SSE) is the latest SASE market variant. SSE is essentially SASE without SD-WAN. Many software and service providers chose to highlight what they consider the next evolutionary step, which is to remove the branch office edge device from the discussion. The primary benefit of SSE as an offer is for sellers that do not have a strong SD-WAN offer. The technical side of the same discussion is that eventually, in a cloud-only approach to IT services, user...
