Originally, the concept of SDN emerged as a way to unbundle a hardware networking device (like a router) into a software-based control plane and a hardware-based data plane. SD-WAN uses a software-based control plane to drive on-premise edge devices to dynamically allocate Wide Area Network (WAN) traffic between MPLS and Internet links.

With SD-WAN, organizations can deliver more responsive, more predictable applications at lower cost in less time than the managed MPLS services traditionally used by the enterprise. In an SD-WAN, a specialized appliance at the sites edge connects to the network services, typically MPLS and at least two Internet services.

Earlier last month, we announced that Cato reached a new SASE throughput record , achieving 5 Gbps on a single encrypted tunnel with all security inspections fully enabled. Companies need encrypted, secure high throughput between their clouds or to the central data centers in their hybrid deployments.

But whats particularly interesting for anyone moving away from a global MPLS network or otherwise looking at WAN transformation is the impact NaaS will have on evolving the enterprise backbone. Only by converging SASE with NaaS can companies eliminate costly, legacy MPLS services. But SASE alone cant replace MPLS.

Carrier MPLS services are really expensive bandwidth. But the reality is that within most providers both MPLS VPN services and public Internet services ride on the same shared network infrastructure. Now that the traffic is routing over the Internet, encryption becomes a must have. For enterprises, SD-WAN makes a lot of sense.

When it comes to SD-WAN, he concedes: Theres a huge business case that SD-WAN products are aiming to solve: replacing traditional MPLS/VPN networks with encrypted transport over public Internet.Internet access is often orders of magnitude cheaper than traditional circuits.

Internet-based VPN gained popularity over the last decade in part as a lower-cost, albeit flawed, alternative to MPLS (Multiprotocol Label Switching). Site-to-site VPNs enable enterprises to securely connect physical locations over the public Internet by creating an encrypted connection between two on-premises appliances.

Many enterprises are replacing their fixed MPLS wide area networks (WANs) with virtualized software-defined WANs (SD-WANs) to reduce costs. Most SD-WAN solutions are encrypted SSL or IPsec tunnels, but new attack vectors may present themselves with data going over the air instead of over wires. 5G and SDN Capabilities Intersect.

SD-WAN isn’t built to improve security, but instead address the rigidity, capacity constraints, and high costs of MPLS. Security in the context of SD-WAN was needed to encrypt the SD-WAN overlay tunnels over the Internet. Security was never a strength of SD-WAN companies and legacy telcos.
