Software Defined Wide Area Networking (SD-WAN) is changing the way that businesses connect to the cloud. With SD-WAN, organizations can move away from closed, proprietary hardware solutions, bringing flexibility and potential cost savings to their operations.
And yet, while SD-WAN technology seems like a solution to many of the problems that businesses are having connecting to the cloud, there are still some concerns around security and that is where Secure Access Service Edge (SASE) comes into the picture.
Before we dive any deeper, let's take a quick look at what we've got covered:
Software Defined Wide Area Networking (SD-WAN) is a seismic shift from traditional WAN technology, where proprietary hardware and software are replaced with virtualization technology that can abstract networking from hardware. The “Software Defined” part of an SD-WAN uses virtualization to create a WAN architecture that allows enterprises to leverage any combination of transport services, including MPLS, LTE and broadband internet services, and create a fabric of connectivity that connects users to applications. SD-WANs use a centralized control plane to intelligently direct traffic across the WAN, increasing application performance, resulting in enhanced user experience, increased business productivity and reduced costs for IT.

The Secure Access Service Edge, better known as SASE, is a technology proposed by Research Giant Gartner. The research house defines SASE as a cloud architecture that converges various network and security functions into a single, cloud security and networking platform. SASE goes beyond what an SD-WAN can offer by incorporating security protocols and increases the reach of the network with support for mobile devices, IoT devices, and other devices that may not have a persistent connection to the network. What’s more, SASE can securely bridge cloud services into the SD-WAN, allowing branch offices and remote users to access services from most any locations. SASE is delivered as a service, minimizing or eliminating the need for specialized hardware or security appliances.
The SASE model allows IT teams to easily connect and secure all of their organization’s networks and users in an agile, cost-effective and scalable way.
