The increasing adoption of SaaS and IaaS applications and infrastructure has been a catalyst for the rapid adoption of SD-WAN architectures. Directly connecting users to SaaS/IaaS instances from branch offices using lower cost internet services to augment (or even replace) MPLS provides the highest performance and user experience.
But, since all web traffic is not created equal, active use of internet connections demands a new approach to security.
At the same time, it’s simply not tenable to deploy an expensive, next-generation firewall at every branch. Therefore, a more intelligent, application-driven security model is enabled by more advanced SD-WAN solutions, such as Silver Peak Unity EdgeConnect. These solutions place just the right amount of inspection at the branch and enable easy, cost-effective service chaining to more advanced – and more expensive – security services deployed in the cloud or in the enterprise data center.
