As the conventional corporate IT network relies on the WAN architecture, the IT administrators often find themselves with a never-ending headache – network configuration. The hardware-based WAN, composed of routers, servers, and other network devices across physical locations, in its nature lacks the flexibility for deploying immediate changes and updates to edge devices. Adding subsidiaries or moving the site to new locations? That’s multiple times of manual configuration and management work! In the face of fast-changing management decisions and network security crisis such as spear-phishing, CIOs and CTOs nowadays should be aware, that without the flexibility, not only would handling the regular requests and addressing the enterprise’s growing connectivity be complex and costly, but the business continuity could be crippled.

Living in the era of 5G, we cannot be luckier to have witnessed the next-generation mobile network (NGMN) being rolled out and incorporating major technological advancements across various industries. The icing on the cake, however, is the simultaneous entrance of Wi-Fi 6. A study conducted by Cisco predicted, that Wi-Fi alone, by 2020, will make up 51% of global IP traffic, more than the total of wired access (29%), and mobile networks (20%).

There is no doubt that SD-WAN has become one of the most prevailing technologies for IT fields due to the advantages of end-to-end visibility, agility, application optimization, and particularly the economical incentives that allows a white-box VCPE hardware to run third-party applications and VNFs (virtualized network functions). Indeed, SD-WAN shares the bandwidth of traditional MPLS connectivity and public Internet so that connectivity between branch offices and headquarter can be far more cost-effective. However, the use of public Internet indicates higher exposure to potential cyber-threats. With the widespread of SD-WAN in the enterprise sector, it is essential to secure the software-defined wide area network before an evolved attack begins to penetrate.
