Abstract: Secure access service edge (SASE) is a revolutionary network security technology for digital transformation of industry by organically integrating cloud, network, computing, and security to support one-step security access anywhere and anytime. The key technologies of SASE include software defined wide area network (SD-WAN), zero trust network access (ZTNA), cloud native network, and network security as a service, which are the inevitable trend of network convergence security architecture evolution. At present, China's SASE industry is still in the early stage of exploration, so it is necessary to seize the development opportunity, strengthen the innovation of technology product development and standard system construction, and promote the high-quality development of SASE industry.
