SD-WAN technology combines strong encryption techniques and strict access controls to secure the WAN traffic and allow the Internet to be efficiently used for the most popular enterprise applications.
FREMONT, CA: Many companies have re-prioritized network transformation and are turning to solutions like Software-Defined Wide Area Networks (SD-WAN) to help them tune their business networks for maximum efficiency. So, what role does SD-WAN play in this? Below are three major advantages that SD-WAN provides:

Better-Quality Application Performance for A Better End-User Experience
Over any underlying networking technology, like MPLS (IPVPN), dedicated Internet access, and broadband, SD-WAN offers policy-based and application-aware routing (fixed and mobile). This means it chooses the best path possible for that particular application's needs based on its prioritization automatically and intelligently.
SD-WAN also provides a number of features that help boost application efficiency over the Internet. While this does not solve all future network efficiency problems–just as with a road network, underlying network functionality is still critical to the path the traffic takes–they do make it more feasible for lower-cost access technologies to address the ever-growing amount of branch traffic, most of which is bound for the Internet.
Enhanced Security
When business-critical data traffic is delivered over shared networks like the public Internet, security is a must. SD-WAN technology combines strong encryption techniques and strict access controls to secure the WAN traffic and allow the Internet to be efficiently used for the most popular enterprise applications. SD-WAN can also help companies enhance their security by making it easier to enforce policies consistently across all sites owing to its central policy-based orchestration.
More Reliable Use of Available Bandwidth
Organizations must find cost-effective ways to expand bandwidth while maintaining a good user experience as applications become more feature- and content-rich. Business workloads move from private data centers to SaaS and IaaS/PaaS powered hosting. SD-WAN balances traffic through all active links into a site automatically. This increases the amount of WAN bandwidth available to consumers, allowing businesses to get more value out of secondary failover connections that would otherwise go unused, reducing the need for regular bandwidth upgrades.
