The network perimeter has dissolved with IaaS, SaaS, and mobile users breaking that barrier and shifting more traffic to the Internet. MPLS was not designed for this new reality. Point-of-sale (POS) traffic went across the IPsec VPN to firewalls in the companys Singapore datacenter housing its POS servers.

At the edge of this network, customers can connect their branch locations, corporate data centers, mobile and remote users to the core network via their preferred carrier services (MPLS, broadband, LTE, etc.) Cato can establish an IPsec tunnel from customers existing equipment such as a firewall in a datacenter or branch location.

The new darling of the networking industry would free us from the shackles of legacy MPLS services. It was cute, shiny, and taught enterprises how to walk — walk away, that is, from MPLS to a network designed for the new world. Native cloud connectivity within the PoPs connects IaaS and SaaS resources.

Best Effort Isnt Always the Best Way I have talked with numerous enterprises that replaced MPLS circuits with SD-WAN. By that I mean, traffic goes to the SASE solution providers PoPs to be forwarded to SaaS or IaaS applications or the Internet. Initially, users and management are often happy. Things work fineuntil they dont.

Most SD-WAN vendors provide basic security features such as encryption, layer 2 access control, and possibly some basic firewall functionality. By using service insertion or service chaining, separate security services such as firewalls and IPS are inserted into the data flow.

When moving from MPLS to SD-WAN appliances, each location will now have its own connection to the Internet. By expanding the attack surface, every office with DIA now requires the full range of security services including next-generation firewall (NGFW), IDS/IPS, sandboxing and more.

The new center of secure access networking design is the identity of the user, device, IoT/OT systems and edge computing locations and their needs for secure access services to cloud-based services directly including an enterprises applications running in IaaS. However, other use cases will drive earlier adoption.
