We still need to connect our infrastructure to the public internet, so the enterprise WAN is still about routers, circuit IDs, and perimeter firewalls. But today, those routers are likely a centrally managed SD-WAN, and those perimeter firewalls could be a CASB or other cloud-based firewall service.
