Cut WAN costs, improve performance, increase security – software-defined wide area networks (SD-WANs) seem to do it all, but can they -- really? Find out as we take a hard look at the myths and realities of SD-WANs.


In this webinar, Steve Garson, President of SD-WAN Experts, is interviewed by Dave Greenfield, Cato’s secure networking evangelist, about the practical questions you should ask when evaluating any SD-WANs.


This webinar will go over:

  • What aspects of network performance can SD-WANs really improve?
  • When is service insertion and service chaining needed?
  • Can SD-WANs really reduce WAN costs?
  • Why is security still a problem for SD-WANs even though they encrypt all traffic?
