Integrated SD-WAN solution becomes the trend

Compared with the traditional network system, SD-WAN is built on a transparent, controllable and predictable white-box system. It can define and virtualize the network resources needed. It has flexible networking, fast provisioning, fast cloud entry, centralized management and control. Many advantages, such as value-added services, can effectively cope with complex network services and become an important direction of current network evolution. According to Gartner's forecast, by the end of 2019, 30% of enterprises will deploy SD-WAN in their branches, and large-scale commercialization will occur within five years. CBInsight's research report also shows that SD-WAN has become the most preferred IT technology for enterprises in 2019.

Because SD-WAN and traditional network architecture are very different, network access becomes more and the application environment is more flexible, which brings additional challenges to its security and performance. Li Hongkai, general manager of Fortinet China, pointed out: "SD-WAN is a cross-border technology. The advantages of traditional network vendors in this field are not obvious, and users need to identify applications, security, quality of experience, performance and other aspects on a network basis. It gives Fortinet a huge opportunity. And in the traditional network architecture, security and large network design are separate, and SD-WAN turns WAN into LAN, security issues will be exposed, Fortinet directly integrates security into the underlying network. In the architecture, users do not have to think about security construction separately, so the integrated design will greatly promote the effectiveness of enterprise network security construction."
