In the latest ZK Research / Tech Target Network Purchase Intention Study, improving network security came out as the top choice to the question of what the respondents’ networking priorities would be over the next 12 months. This shouldn’t be a big surprise, as it seems like there is a highly-publicized breach in the news almost every month now. Many of the IT professionals I’ve talked to have told me that every time there is media attention on one of these attacks, the business leaders at their organizations get involved and want to be sure the same thing doesn’t happen at their business.
The problem for most security leaders today is that network security is a losing battle. Traditional security devices operate on a signature basis and assume that the number of ingress/egress points are limited to the points in the network where one of these tools is placed. But that’s not the case at all any more. Today, partner connections, consumer devices and direct Internet access from a branch have significantly changed the number of attack points in a network and made it hard to defend.
Solving this problem requires a new approach to security, as IT professionals are working with archaic tools. Think of it this way: if you’re running a business on next-generation IT infrastructure, why are you trying to secure it with security tools built for legacy IT? Not evolving the security strategy doesn’t make sense and puts the business at risk.
Most of the marketing around SD-WANs has been about lowering costs and improving user experience and justifiably so as it does a great job of that. However, there’s a third leg to the SD-WAN value stool, and that’s improved security posture. SD-WANs can improve network security in the following ways:
There’s currently a tremendous amount of interest in the topic of SD-WAN and I think we’ll see very strong adoption over the next few years. For those of you reading this that are looking to evolve to one, use security as an additional point of justification.
