Cisco SD-WAN


The rise of cloud-based applications and IoT is impacting existing wide area networks across all industries. The need to increase bandwidth, optimize cloud connectivity, and improve security posture is challenging with traditional WAN architectures. Furthermore, the disparate nature of WAN infrastructure makes it hard to gain comprehensive visibility of applications and infrastructure, which hinders failure resolution and effective resource forecasting.

Gartner estimates that “by 2020, more than 50 percent of WAN edge infrastructure refresh initiatives will be based on SD-WAN (Software Defined WAN) versus traditional routers.”


Cisco SD-WAN (Viptela) is a cloud-delivered overlay WAN architecture that significantly drops WAN costs, reduces the time to deploy services, builds application resiliency and provides a robust security architecture for hybrid networks. Viptela’s vAnalytics dashboard delivers visibility and insights necessary for IT to isolate and resolve issues promptly, and it delivers intelligent data analysis for planning and what-if scenarios.

Cisco has one of the most widely deployed enterprise-grade SD-WAN solutions with:

  1. Large deployments in retail, healthcare, financial services, energy and more across Fortune 2000 enterprises
  2. Thousands of production sites in every major industry
  3. vAnalytics benchmarking data across hundreds of customers
  4. Compliance with PCI, HIPAA and other industry standards
