Highlighted in Gartner’s 2019 Hype Cycle, secure access service edge (SASE) is the next wave of software-defined wide-area networks (SD-WAN), which converges the WAN edge and network security into a cloud-based, as-a-service delivery model. SD-WANs have already paved the way toward network convergence, but SASE takes it a step further by combining elements of SD-WAN and network security into a single cloud-based service. SASE supports all types of edges, including WAN, mobile, cloud, and edge computing, and instead of stringing together multiple products, SASE uses a single-pass, cloud-based architecture to process traffic faster.
