The companies use SD-WAN to offer a high-quality user experience, resulting in increased business productivity, agility, and reduced IT costs.

FREMONT, CA: A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that enables businesses to connect with the users to applications using any combination of transport networks, such as MPLS, LTE, and broadband internet services.

To safely and intelligently direct traffic across the WAN, an SD-WAN employs a centralized control feature. It improves application efficiency and offers a high-quality user interface, resulting in higher company success, greater agility, and lower IT costs.

Unlike conventional router-centric WAN architecture, the SD-WAN model is built to completely support applications hosted in on-premises data centers, public or private clouds, and SaaS services such as Salesforce.com, Workday, Office 365, and Dropbox, all while providing the highest level of application results.

How do SD-WAN solutions address classic WAN challenges?

Increased speed of deployment

Companies can quickly and securely deploy individual sites or even a group of them using zero-touch provisioning. As most features are handled automatically, they won't need many engineers to work on it.

The intuitive management platform allows companies to handle all the site-specific configurations from a single location. SD-WAN solutions also include an integrated control system, which increases network visibility while simplifying implementation and troubleshooting.

Improved security

The network administrators are excited because they know that every site is more effective and safer from network threats. To minimize human error, policies are now controlled and automated in a single location (controller).

It is a critical factor to consider. SD-WAN depends on a range of proprietary, non-standard solutions, so the security advantage cannot be presumed. Since these systems are not as widely used as traditional WANs, there is a greater risk that they contain security flaws that have not been discovered.

Reduced costs

It's not like SD-WAN is always an economical option than traditional WAN. But it provides the companies with flexibility. They can change the network policies and topologies much more quickly and efficiently to adapt to business or internal demands.

Usually, the SD-WAN provider would also provide a firewall service at the site network. Its policies are also managed at the controller level, eliminating the need for internet traffic to be routed through the hub. Companies will save money on MPLS line bandwidth.
