Security is much more than just a product. It isn’t just an IT departments responsibility, it’s a way of working that affects a whole business. Tune in to our experts as they discuss our design philosophy, its application with customers, the inherent security of SD-WAN, and much more.

SD-WAN technology delivers application-centric networking by dynamically choosing the best path for each application in real time.
It can enhance efficiency for cloud-based applications through local internet breakout, removing the need for all traffic to be routed through a central location. And SD-WAN can enable connectivity in difficult or expensive to reach areas, as well as enhanced resilience through the use of multiple providers and diverse technologies including 4G and 5G.
But SD-WAN isn’t a one-size-fits-all solution. Some applications may benefit from a hybrid architecture that combines SD-WAN and MPLS to achieve the right balance of performance, reliability, security, and value.
Our network architects will help you navigate every decision, including which SD-WAN platform – Catalyst or Meraki – is right for your business.
