Your Comprehensive Guide to SD WAN and Its Major Business Advantages

As your organization reaches a certain size, wide-area networks (WAN) become necessary, but establishing Multiprotocol Label Switching (MPLS) across several locations may be both expensive and time-consuming.

On the other hand, a software-defined wide-area network, or SD-WAN, may be put up quickly while also cutting costs and improving application performance.

If built to match your standards and needs, an SD WAN can be the solution to all of your issues.

What Is SD-WAN?

“Software-defined wide area network” (SD-WAN) is a particular type of “software-defined networking” (SDN). SD-WAN can manage a wide range of corporate connections, such as 4G, broadband internet, LTE, and MPLS.

By using the internet or cloud-native private networks, it detaches traffic monitoring from specialized proprietary gear. With this unique method, administrators may more efficiently use bandwidth, ensure data security, and reach higher levels of performance for critical applications.

How Does SD-WAN Function?

With SD-WAN, you can control your whole extended network, even if the devices are in different places. This may imply a large number of offices or devices used by workers working remotely.

If you want to add a new device to your network, all of your network’s protocol and system settings will be fully set up and ready to use the moment you connect it (remotely).

Main Benefits of SD-WAN

With the support of a central SD-WAN provided by the cloud, IT professionals may achieve efficient routing, attack prevention, and simplified WAN management.

The following are the top four benefits of utilizing SD-WAN for your business’s infrastructure.

Cost Reduction

SD-WAN clients don’t have to be connected to a central network or pay for services they don’t need. This makes SD-WAN a much cheaper alternative to traditional wide area networks (WANs) like MPLS.

When businesses make the transition to SD-WAN, they often notice a decrease in their monthly rates of about 40 percent on average.

SD-WAN is a big reason for this because it lets businesses pick and choose the access methods, carriers, hardware, and other network components that work best for them.

Broadband Internet access and mobile 4G are two examples of ways to connect to the Internet. Through it, companies can save a lot of money on their budgets instead of using the more expensive MPLS network for some low-priority traffic.

Enhanced Performance

Thanks to real-time traffic management, administrators may continually monitor the status of each connection linked to SD-WAN gateways.

IT experts identify apps related to WAN traffic and prioritize certain applications using policy-based management. When a connection breaks, traffic may be diverted rapidly, enhancing application performance and availability on a case-by-case basis.


SD-WAN can improve the user experience by using several network lines simultaneously. Nonetheless, it is important to point out that doing so also makes the site more reliable.

SD-WAN, which provides a secure overlay, can combine a highly customized and diverse assortment of network connections to provide a safety net and almost remove the worry of network disruptions. In a word, software-defined wide area networking (SD-WAN) gives enterprises the ability to “supercharge” their networks, making them more durable and secure.

Enabling Cloud Usage

As organizations implement an ever-expanding array of cloud-based services, the amount of data transported through a wide area network (WAN) grows dramatically.

As such, the total cost of operating the firm rises. The good news is that SD-WAN can reduce this cost by using low-cost local Internet connections, enabling direct cloud access, and reducing the amount of traffic transported across the backbone WAN.

According to the conclusions of an IDC survey, around one-quarter of respondents expect SD-WAN to result in cost savings of up to 39%, while the other two-thirds expect relatively modest reductions of 5–19%.

Business Agility

Another compelling reason to use SD-WAN services is improved network performance and agility. SD-WAN automatically routes traffic through the connection that delivers the maximum throughput and the greatest degree of stability, considerably mitigating common network issues like jitter and latency.

SD-WAN makes it easy to quickly deploy WAN services such as bandwidth and firewalls. As a result, organizations may now decentralize their operations to branch sites without the need to dispatch IT personnel.

As business demands change, bandwidth may simply be raised or lowered, giving organizations greater agility to stay one step ahead of their competitors.


Companies are actively investing in digital transformation to fulfill the demands of a remote and mobile workforce.

Due to the increasing complexity of the network edge, some organizations are using SD-WAN to improve application performance and the user experience regardless of the user’s location.
