Paving the Way to Secure SD‑WAN

No matter where an organization is on its digital transformation journey, its technology leaders are assessing SD‑WAN (software-defined wide-area networks). Whether already part of the strategy, or still under consideration, SD‑WAN has emerged as the predominant technology to access the multi-cloud environment.

 

By abstracting the service layer from infrastructure, SD‑WAN offers enterprises a more efficient and cost-effective way to manage networks. Over the past decade, increasing numbers of organizations recognized how SD‑WAN enables MPLS bandwidths with less expensive Internet connectivity. SD‑WAN’s policy-based forwarding, application awareness and centralized management have made it the on-ramp of choice to the cloud for many enterprises.

 

SD‑WAN is quickly evolving from upholding physical on-premises connectivity to becoming cloud-centric. This was accelerated by the COVID pandemic, where remote work became widespread, and redefined networking in the process. This disruption resulted in more sophisticated threats, which in turn has elevated the urgency and importance of holistic security.

 

In response, this new reality for SD-WAN necessitated employing a new policy-based framework of security management known as Secure Access Secure Edge (SASE) in conjunction with Zero Trust (ZT) authentication to access cloud-based applications and data. Adoption of Secure SD-WAN requires a complex set of capabilities in networking and optimization.
