Secure access service edge (SASE) is a network architecture that rolls software-defined wide area networking (SD-WAN) and security into a cloud service that promises simplified WAN deployment, improved efficiency and security, and to provide appropriate bandwidth per application.

Because it’s a cloud service, SASE (pronounced “sassy”) can be readily scaled up and scaled down and billed based on usage. As a result, it can be an attractive option in a time of rapid change.
