SD-WAN: Why It’s the Best WAN Solution for Your Business Needs


Cloud-based solutions are fast revolutionizing the way we do business. From data centers to networks, the cloud has made technological needs mobile and cost-effective. One of the areas where it has proven to be beneficial is for wide area networks (WAN), specifically through software-defined networking (SDN). This brought us an SD-WAN.

Simply put, a software-defined WAN (SD-WAN) allows for a secure hybrid overlay, transforming the network so that it may be managed and controlled virtually. Experts estimate that by 2020, more than half of businesses will shift to SD-WAN from traditional technologies such as routers.

Secure SD-WAN

Introduction to a Secure SD-WAN

Why are more and more people upgrading to a Software-Defined WAN? Here are some compelling reasons:

1. It can reduce costs by 50% or more

By migrating from MPLS to hybrid WAN, a business can optimize usage and capacity of transport of the network by having 10x more bandwidth, which translates to great savings. Companies that implement this WAN solution can benefit from a cost/Mbps reduction of up to 80%.

2. Capability time is shortened.

Especially helpful when expanding a business, SD-WAN offers quick and efficient deployment of new branches with any kind of transport – whether LTE, broadband, MPLS, or VSAT. Since it offers centralized management, SD-WAN can implement policy or enable new services right away. It can also automate workflow with its built-in automation. A full M&A integration can be done as quickly as two weeks.

3. There is no possibility of an outage for any application.

More stable than traditional networks, an enterprise-class SD-WAN promise zero outages through the use of multiple hybrid links with active-active capability. This means traffic can be steered in real time in case an upstream network issue arises. SLA-based application policies may also be customized according to business specifications. Network failures are minimized due to this feature.

4. You will benefit from a cloud-optimized network.

By securing the WAN through the cloud, it can be extended seamlessly to Azure and AWS. SaaS performance for various applications such as Office 365 and Salesforce will be enhanced as a result. SD-WAN technologies can also unify enterprise WAN policies for both on-site and cloud-based workloads, ensuring improved overall performance.

5. It guarantees a secure and hardened network.

As with other cloud technologies, SD-WAN is highly secure and robust. It reduces and practically eliminates threats and attacks to the network by segmenting data within the cloud from partner networks, guest wireless, and IoT, among others. It also allows for on-demand inclusion of network services such as Palo Alto and Zscaler. This is especially advantageous for companies that have stores that require multiple guest wireless set up in various locations.

Truly, SD-WAN is the best WAN solution for your business needs because it can reduce costs by 50% and increase bandwidth by 10%, expedite expansion through the quick setup of new branches and services, eliminate the possibility of outages, and optimize other cloud-based applications, all on a secure, hardened network that is virtually impenetrable. Allow it to transform and revolutionize the way you do business.
