The term Secure Access Service Edge, short for SASE, was first showed in an analysis by Gartner in 2019. In concept, SASE is the simplified architecture which converges SD-WAN with network security, and delivers applications and services from cloud to edge. The rise of SASE is mainly contributed by the continuous momentum of edge, cloud-native and mobile computing. In the digitalized business world today, data is largely generated at the network edge and cloud, and thus applications have to be deployed where data is generated to minimize the latency and boost performance.

SD-WAN has been one of the most commonly deployed networking technology for the past couple years, and because of its technological and economical benefits, enterprises of all sizes and scales have broadened their use cases for SD-WAN. Today, it has evolved to meet a diverse vertical for wider application span.

Airtight security is nonnegotiable when it comes to adopting IoT technology for mission-critical applications in all Industry 4.0 scenarios. Intelligent manufacturing, for instance, can be protected against network manipulation, attacks and data theft but only if its product line machines and devices are correctly identified and properly secured; and such security requires hardware appliances equipped with seamlessly integrated security chipsets capable of silently safeguarding communications between all devices and machines within heavily networked infrastructures.

The wide adoption of cloud computing in both public and private sectors has changed the communications and interactions between organizations and their uses or customers. This paradigm shift has in fact continued to drive enterprises to improve their network service performance in order to meet the expectations of the public. However, the increased market competition has also changed the way organizations upgrade their IT infrastructures.

The networking ecosystem has already witnessed the widespread deployment of SD-WAN topology, and indeed, this software-defined WAN optimization architecture has been one of the most discussed buzzword in the industry. In the current phase, most SD-WAN adopters have deployed their solution either on off-the-shelf devices or an integrated package of hardware and software from leading vendors in the market, or perhaps a managed SD-WAN solution leveraging some degrees of MPLS service. Driven by the technological and economical advantages, the SD-WAN momentum continues to penetrate the market, and recently, there has been an evolution of this virtualized, software-defined WAN architecture, which can be considered as the next phase of SD-WAN.

Without any doubt, SD-WAN has been one of the most dynamic technological innovations in the networking ecosystem. The software-defined networking architecture enables IT management with end-to-end visibility to monitor and control all the sites, which is also the reason why SD-WAN has rapidly replaced legacy router-based WAN architecture in recent years. SD-WAN helps businesses address the challenges in connectivity, agility and service availability for their global or remote branches.
