SD-WAN vendor comparison, new normal of corporate network seen from the latest survey of Gartner et al.

The rapid spread of remote work, which originated from the Korona-ka, is changing the way corporate networks should be. Gartner proposed SASE (Secure Access Service Edge) in 2019 as a new framework for the cloud era, which provides unified network and security. One of the core products in terms of networks to realize SASE is "SD-WAN (Software Defined WAN)", which refers to a wide area network defined by software. Here, we will introduce the trends of SD-WAN, which will become more important in the future for companies to promote their business, including the latest Gartner survey results.

What is SD-WAN and what is the required background?

SD-WAN (Software Defined-Wide Area Network) is a wide area network that is virtually defined by software, or technologies and products for implementing it. In the past, hardware such as routers, switches, servers, and storage existed as constituents of networks, and it was necessary to control each of them, which was complicated. SDN (Software Defined Networking) is a technology that enables centralized control of these by software, and SD-WAN extends the scope of SDN not only to local areas but also to WAN, which is a wider network. By using SD-WAN, the network connection can be controlled by software to reduce the load on communication and lines, there is no need to go to a remote location to set up equipment, and the traffic monitoring environment can be improved. There is a merit that the operation cost can be reduced because it can be unified. Also, one of the main functions that can be implemented on SD-WAN is "Internet breakout". It is a function that makes a specific communication to access the Internet go through a gateway different from other communication. With the spread of telework, the number of bases connected to the Internet is increasing, and the amount of traffic is increasing, and the traffic to the networks owned by enterprises and the VPN environment are becoming tight. Internet breakouts can reduce the impact.

Gartner Announces Latest Evaluation of SD-WAN Vendors

On September 20, research firm Gartner announced the 2021 edition of the "Gartner Magic Quadrant for WAN Edge Infrastructure," a survey of WAN edge infrastructure closely related to SD-WAN. Six leaders were selected: VMware, Fortinet, Versa Networks, Palo Alto Networks, Cisco Systems, and HPE (Aruba & Silver Peak). Introducing leader companies, focusing on their strengths and points to note.

leader	Challenger	Niche player
VMware Fortinet Versa Networks Palo Alto Networks Cisco Systems HPE (Aruba & Silver Peak)	Huawei Citrix	Cradle Point Nuage Networks Peplink Barracuda FatPipe Networks Riverbed

-VMware We develop competitive products such as hardware, software, and gateways, and our strength is that we have more than 14,000 customers, financial resources, and large-scale global channels. On the other hand, it should be noted that the security function depends on OEM by Menlo technology, so it may not be possible to respond quickly to the security needs of new customers. -Fortinet WAN Edge products provide versatile security features in addition to application performance optimization and SD-WAN capabilities. Another strength is the high customer experience score. On the other hand, he points out that there is no strong security partner ecosystem needed to build multi-vendor SASE capabilities.・ Versa Networks is operated globally and supports clients of all sizes and industries. Gartner points out that he hopes to invest in SASE, 5G, SD branches, and artificial intelligence (AI) / machine learning (ML) in the future. It continues to grow above the market average, and there are many inquiries to Gartner. It is noted that there are many large-scale competitors.・ Palo Alto Networks' main product is Prisma SD-WAN. It can be integrated with Prisma Access for cloud access security to provide a single-vendor SASE solution. Its strength is that it has an analysis function and utilizes AI / ML functions to provide products. Note that there is a limit to optimizing application performance because there is no core WAN optimization feature. Cisco Systems He has two branded products, the Cisco SD-WAN with Viptela and the Cisco SD-WAN with Meraki. With a wide range of products and a wide range of global channels, our strength is that we can respond globally to the use cases of almost all companies. Note that Gartner's customers are prominently saying that pricing is high in the market.・ HPE (Aruba & Silver Peak) The main product is the Aruba Edge Connect SD-WAN Edge platform acquired by Silver Peak. It also offers Aruba SD-Branch, which offers an integrated architecture with AIOps, LAN, WLAN, WAN and security. Its strength is that it can handle the use cases of customers of all sizes. On the other hand, he points out that having two established products on the market can lead to customer confusion.
