Businesses value security, which is why as opposed to its alternatives, SD-WAN offers great protection for your network. It provides secure connectivity by offering end-to-end encryption across the entire network.
SD-WAN can make it easy to pass data through multiple WANs. A company can reduce the amount of money they spend on WAN links and add cheap broadbands to the mix. Even if a link fails, the application can dynamically route traffic.
While SDN and SD-WAN have the same background and start with SD, they are not the same. You need to understand the difference between these services to choose the best one for your company.
