We were a bit surprised to find out that secure, direct Internet access was the top driver. The Internet Challenge for MPLS and Hybrid WAN Traditionally, MPLS was always considered a private network. This had two ramifications: many enterprises did not encrypt their MPLS connections or inspected MPLS traffic for threats.

Due to security and compliance concerns, some vendors handling such sensitive data cannot expose services to the public Internet and therefore host their own on-premise data centers. The data transfer between DoorDash and payment processors needs to be encrypted to protect customers’ privacy and sensitive data. As shown in Figure 2.,

In both cases, the customers wanted to extend an MPLS-only WAN into a hybrid WAN based on a combined MPLS and Internet connectivity. MPLS security is based on the fact that it is a private network vs. the public Internet. puts it: although the public Internet always carries some risk, the reality is that MPLS is also a shared medium.

In many infrastructures, the inflection points are at the network edge, where VPN gateways authenticate and encrypt remote-access traffic. This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN). The richest data sources are from the VPN devices or firewalls.

In order for companies to realize SD-WANs cost savings and cloud performance benefits, branch offices must be connected directly to and communicate across the Internet. Traffic Protection The reliance on the public Internet requires the SD-WAN to protect traffic against eavesdropping. This requires a shift in our security models.

Virtual Private Networks (VPNs) have become one of the cornerstones of secure communications over the internet. VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. VPN traffic is encrypted and decrypted at the transmission and receiving ends of the connection.

Traditional hub-and-spoke networking has enterprises backhauling WAN traffic from branches over MPLS circuits to a central site and applying security policies before sending the traffic to the cloud or the public Internet. All PoPs are interconnected using fully-meshed, encrypted tunnels to protect traffic once it is on the network.

The core value proposition of SD-WAN is the use of a standard, low-cost Internet link to augment an expensive managed, low-latency and guaranteed capacity MPLS link. MPLS isnt encrypted by default: MPLS relies on the carrier private network for security because the data doesnt flow on the public Internet.

SD-WAN is a flexible solution that integrates low-cost Internet transports into a virtual WAN connection. They are not vulnerable to the kinds of attacks seen on the Internet, since hackers can’t get to them, which is why they’re perceived as being secure. Many MPLS customers today add VPN encryption to secure the network.
