SD-WAN for enlightened

What I don't understand is how do all these newer, SD-WAN vendors, differ
from any of the managed FireWall companies that have nice pretty GUI's and
web management? For example, Sophos, Meraki, Fortinet, and the other large
firewall vendors that do dual wan, virus filtering, remote management, etc?
