Gartner - Market Trends—SD-WAN and NFV for Enterprise Network Services

Thank you for your interest. The {{resourceType}} is now [[available for access]]

This Gartner Market Trends report emphasizes the correlation between the increasing growth of software-defined wide-area network (SD-WAN) and internet in enterprise WAN, and competition in service management. “Network service providers must rethink their longtime settled go-to-market and service delivery practices to ensure success meeting new enterprise demands,” Gartner analysts say.


  • SD-WAN is becoming the de facto option chosen by enterprises in WAN edge renewals
  • Network service providers are increasingly challenged by competition in overlay SD-WAN management
  • The market remains hesitant around network function virtualization-based WAN edge adoption
  • Enterprises need to rearchitect network security for cloud, internet and SD-WAN, creating opportunities for convergence
By 2024, to increase agility and enhance support for cloud applications, 60% of enterprises will have implemented SD-WAN — up from less than 20% today.
