Top 3 Trends of SD-WAN

By Enterprise Networking Mag | Tuesday, June 30, 2020

Software-defined wide-area networking (SD-WAN) has become the most disruptive network technology with WAN management and cost reductions being the main drivers of growth.

Fremont, CA: The market for SD-WAN is still booming with distributed organizations widely deploying the technology to solve WAN bandwidth limitations, provide reliability/resiliency, and improve the user experience quality for cloud-based applications. Many suppliers are rapidly innovating and maturing their SD-WAN products with the help of innovations in cloud onramps, security, support for leading SaaS applications, and management platforms.

Vendor viability

With over 50 active suppliers, SD-WAN is a highly dynamic market. Therefore a basic SD-WAN functionality is becoming standard across all routing and next-generation firewall providers. With more suppliers offering SD-WAN, differentiating among various feature sets can become more complicated. Top 10 SD-WAN Consulting/Service Companies - 2020

Improved support for SaaS

Organizations depend on dozens of software as service (SaaS) suppliers to provide best-in-breed applications for unified communications, office suites, CRM, accounting, and many more specialized services. It is challenging for IT to guarantee the quality of services to these applications. Every SaaS provider has a unique set of services, APIs, security mechanisms, and management tools. 

Many SD-WAN platforms can recognize traffic through their IP address and the type of traffic from the leading SaaS providers. Some SD-WAN products have particular business relationships and tight integration with leading SaaS platforms.

Built-in security

SD-WAN leverage the abundant bandwidth of relatively UN-secure internet connections, starting from exposing branch locations and edge devices to the security attacks and data breaches. Thus, SD-WAN deployments need additional security to ensure that the corporate policy is imposed at distributed locations. The security features should include policy controls, traffic visibility, and protection against direct threats and attacks.

SD-WAN products must offer robust visibility into applications, protocols, and devices for auditing and compliance. SD-WAN platforms now provide automated policies as to which traffic should traverse specific network links and the ability to whitelist and blacklist traffic from particular locations. During 2020, SD-WAN suppliers will continue to improve the depth and breadth of their native network security capabilities.
