A secure access service edge (SASE) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection (user, device, Internet of things (IoT) device, or edge computing location) rather than a data center. It uses cloud and edge computing technologies to reduce the latency that results from backhauling all WAN traffic over long distances to one or a few corporate data centers, due to the increased movement off-premises of dispersed users and their applications. This also helps organizations support dispersed users and their devices with digital transformation and application modernization initiatives. Security is based on digital identity, real-time context, and company and regulatory compliance policies, rather than a security appliance like a firewall. A digital identity may be attached to anything from a person to a device, cloud service, application software, IoT system, or any computing system. The term was coined in 2019 by marketing analyst firm Gartner. From Wikipedia
