IT pros need to weigh in on that ‘sassy’ security model

The secure-access service edge (SASE) model developed by Gartner ties into SD-WAN, edge computing and SD-Branch, so it warrants attention from networking teams.

Cloud services that provide both network and security intelligence are gaining popularity because they are easy to consume and they improve agility. Similarly, a model known as SD-Branch is providing network and security functionality at the WAN edge on a single platform.

Both of these trends have contributed to the development by Gartner of a network architecture known as the secure-access service edge or SASE, which “converges network (for example, software-defined WAN) and network security services (such as [secure web gateways], [cloud access security brokers] and firewall as a service).” SASE (pronounced “sassy”) would primarily be delivered as a cloud-based service, Gartner says.

This model is gaining awareness among enterprise IT leaders, and it has the potential to become a leading architecture at the edge during the 2020’s, but these leaders should be cautious about jumping immediately on the SASE bandwagon.

The status of SASE

Today, SASE is an intellectual discussion; it is not a market, and comprehensive solutions are not currently available. The breadth of technology required to deliver SASE means that suppliers have incomplete offerings, often with limited integration between elements such as LAN, WAN and security. Dozens of vendors are positioning themselves as SASE suppliers, but none is likely to emerge as a clear leader in the next two years.
