Secure SD-WAN
What Is SD-WAN: How It Works, How It Differs from VPN, and How to Choose One
We break down what an SD-WAN solution consists of, how it chooses a route and what it does when a channel degrades, which deployment scenarios and common mistakes there are. We give a self-check list and criteria for choosing a solution.
What Is Secure SD-WAN and Why Does Business Need It
Secure SD-WAN combines software-defined network management with security functions at the perimeter of every branch office. This article is an introductory guide for anyone considering SD-WAN as an alternative to MPLS.
SD-WAN vs. VPN: How the Approaches to Corporate Networking Differ
We compare SD-WAN and VPN by policy management, behavior when a channel is lost, and operational load. We give a step-by-step migration scenario with a coexistence period and a readiness checklist for the transition.
