Network Security and Direct Internet Access: The Foundation of MPLS WAN Transformation
CATO Networks
SEPTEMBER 15, 2018
In a recent webinar we conducted at Cato , we asked the audience a poll question: What is the primary driver for your SD-WAN project? We were a bit surprised to find out that secure, direct Internet access was the top driver. Why is security such a big deal with SD-WAN? But, is the cure worse than the disease?
