AdRolls Global Director of IT Adrian Dunne faced several challenges when attempting to scale the companys Internet-based VPNs. Network performance, security, and redundancy all became major issues as AdRoll grew, prompting Dunne to search for a VPN alternative. So, what makes SD-WAN such an attractive VPN replacement?

As remote and hybrid work schedules become more common, companies are deploying secure remote access solutions, such as virtual private networks (VPNs) to support them. High-Performance Internet Access is Essential for the Modern Business In the past, most of an organizations employees worked on-site.

What is a Remote Access VPN and How Does it Work? A remote access virtual private network (VPN) is a solution designed to securely connect a remote user to the enterprise network. A remote access VPN creates an encrypted tunnel between a remote worker and the enterprise network.

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.

They may use unsecured public Internet connections that are vulnerable to eavesdropping and man-in-the-middle attacks.

The data payload itself must also be encrypted for strong security.

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.

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.
