A Quick History Lesson
Believe it or not, the term Software-defined Wide Area Network (SD-WAN) was first introduced back in 2014, practically ancient history when it comes to networking at the edge. It’s now well recognized and increasingly adopted as the cloud-first way to transform WAN architecture, improving application performance, enabling more efficient connectivity, and reducing network complexity.
Secure Access Service Edge, known as SASE, describes the cloud-first architecture for both WAN and security functions, all delivered and managed in the cloud. In short, SASE is a blend of SD-WAN and cloud-delivered security.
