Secure access service edge (SASE) platforms deliver converged network and security-as-a-service capabilities, such as software-defined WAN (SD-WAN) and secure access to the web, cloud services and private applications regardless of the user’s location, the device used or where that application is hosted. These offerings primarily use a cloud-centric architecture delivered as a platform by one vendor.
SASE securely connects users and devices with applications, services and other users. It supports branch office and remote worker connectivity and on-premises general internet security, private application access and public cloud service provider access use cases.
