The overall market grew 45% in Q3 2021 compared to the prior year, and the projected growth year-over year for all of 2021 is 36% as enterprises recognized the business benefit of SD-WAN technology. If you’re shopping for an SD-WAN vendor today, the landscape looks like this: The top five vendors in revenue share for 2020 were Cisco, V Fortinet, Mware, Versa and HPE/Aruba, according to Dell’Oro Group. For example, Cisco bought Viptela, VMware bought VeloCloud, Oracle bought Talari, Palo Alto Networks bought CloudGenix and HPE/Aruba bought Silver Peak, Juniper bought 128 Technology.

With SD-WAN, enterprises can replace multiple physical devices with a single appliance or virtual appliance, load SD-WAN software onto a server in a branch office, retail store, restaurant or manufacturing facility, or choose a fully managed, cloud-based service.įor those who want to take advantage of this new functionality, choosing and deploying the right SD-WAN solution has become a more complicated endeavor because SD-WAN cuts across security, networking, application performance and cloud services. SD-WAN technology has evolved from WAN optimization on steroids to encompass a comprehensive set of features that include core routing functionality, advanced WAN optimization and application-aware firewalls, all managed via a centralized software overlay. Today, SD-WAN has emerged as a key enabler of the post-COVID enterprise in which mission critical applications live in multiple clouds, employees connect and collaborate from everywhere, and remote access to applications like Office 365, Salesforce and Zoom must be fast, secure, reliable, optimized, and automated for maximum business productivity and end user satisfaction.
