Secure SD-WAN: Staying Secure When the Internet is the New WAN
The move of data and applications to the cloud has put pressure on the WAN; users need good performance which usually means high bandwidth and low latency. However, specialist WAN technologies such as MPLS are expensive, and can't always meet the requirements of visibility, flexibility, control, resiliency and efficiency.
By being transport independent, SD-WAN technologies are able to automatically share traffic across different types of internet links to choose the best route.
Now you can use relatively inexpensive broadband links alongside – or instead of – more expensive dedicated WAN technology, and offer application level SLAs to users.
