What is SASE?

Secure Access Service Edge (SASE) combines networking and security functions in the cloud to deliver secure access to applications, anywhere users work. The core functions include software-defined wide area network (SD-WAN), firewall as a service, Secure Web Gateway (SWG)s, Cloud Access Security Broker (CASB), and zero Trust Network Access (ZTNA). The goal of the SASE model is to consolidate these functions — which were traditionally delivered in siloed point solutions — in a single, integrated cloud service.

Secure access service edge (SASE)

What’s driving the move to the secure access service edge?

Digital business transformation and the shift to a more distributed workforce are driving the need for anywhere, anytime access to resources, wherever they may exist. These changes require networking and security to move to the cloud, where they can be delivered as a single converged service with flexible deployment and consumption models.

The shift toward a more distributed workforce is not new, but it has recently accelerated. While the principles of SASE have been forming for years, SASE is now in the forefront as remote access to applications and “work from anywhere” became a top organizational priority. With this shift, the datacenter is no longer the hub – the user is. To give them secure access to work resources and applications, users must now be treated as a “branch of one.”

But the traditional branch isn’t gone. Some people may head back to the office soon and worker distribution will inevitably shift again. Even as employees start returning to the workplace, a recent Gartner survey revealed 82%of respondents intend to permit remote working some of the time.[1] Throughout these ever-changing times, users still expect a seamless connection to the applications they need.

SASE is based on cloud-native capabilities that simplify the IT environment by bringing networking and security teams closer together to drive stronger collaboration and faster response times. For the best results, Gartner recommends that organizations select a single SASE vendor that can provide a broad set of security functions and flexible, high-performance networking that’s backed by a reliable track record.
