The emergence of SD-WAN provides a modern take on WAN architecture. As enterprises shift towards multi-cloud environments by adopting new Software as a Service (SaaS) applications and leveraging Infrastructure as a Service (IaaS) platforms, they face ubiquitous information security threats and compliance issues due to a larger attack surface. SD-WAN allows network administrators to easily manage and control Wide Area Networks (WAN) with greater flexibility and intelligence. With SD-WAN, the IT organization is now better equipped and positioned to strike the perfect balance in adopting modern SaaS applications and IaaS platforms, optimizing bandwidth usage, and ensuring data security – allowing organizations to realize ROI from their IT investments.
