Networking is the backbone of multi-site organizations. Given its importance, it shouldn’t be a surprise that geographically dispersed businesses are looking for ways to streamline and improve their network connectivity. According to IDC’s SD-WAN Infrastructure Report, the technology will become a mainstay in the enterprise networking market, growing to a $5.25 billion industry by 2023. As traditional WAN technologies struggle to meet the productivity demands of today’s cloud-first business market, SD-WAN is increasingly becoming the go-to for technology leaders. In addition to the simplicity and visibility provided by a virtual network, there are multiple benefits that SD-WAN provides.

Below are several benefits that are poised to make SD-WAN the go-to solution for network architecture.

What is SD-WAN?
  1. Security

With cyberattacks increasing at an alarming rate, organizations are scrambling to find ways to secure their data and protect their users. This means that they need to protect any possible gaps in their infrastructure that hackers can exploit. One key component of networking security is encryption. SD-WAN allows for the encryption of any data that is being transmitted. This adds a layer of data security in addition to existing security solutions like firewalls.

Additionally, SD-WAN can provide network engineers with the ability to isolate security breaches by segmenting data flow. This means if a cyberattack takes place, an IT manager can segment that breach by isolating it to a particular device or network group, thus preventing it from spreading to the rest of the organization.

  1. Flexibility

In traditional WAN configurations, all networking traffic flows through a primary link. Most businesses have a backup link in case the primary link goes down, however, this link does not see normal traffic, and it is only used in emergency situations. In SD-WAN, you can configure traffic to automatically switch between links if one link goes down or traffic becomes congested on the primary link. This is one of the primary benefits of SD-WAN, as it not only prevents networking slow downs, but it also allows business to get more use out of their secondary link.

  1. Cost Control

Although implementation of SD-WAN requires an initial investment, the features of the technology allow for greater cost control and long-term savings over time. Additionally, with the innate flexibility of SD-WAN, you can utilize less expensive connections, such as internet or LTE.

  1. Performance

Applications have become the core of business operations today. Poor application performance directly translates to a drop in productivity, which can compromise business revenue. Today, many businesses rely on Cloud applications, which are directly accessible through the internet. However, in a traditional WAN configuration, branch network traffic goes from a branch, to the data centre, and then to the internet. This is known as network backhauling, ad lead to poor Cloud application performance. With SD-WAN, you can allow your branches to connect directly to the internet without sacrificing security.


The Workplace of the Future is going to be increasingly dependent on technology because the benefits of incorporating evolving tech practices into your business are evident through improved performance, flexibility, and cost control. This is also applicable to organizational connectivity.

As organizations expand, so too do their connectivity requirements. With a growing network and the limits placed on connectivity by standard WAN technology, software-based WAN is the next step in networking The advantages described above can put you as an IT Manager or business owner on the forefront of technology.
