What is Secure Access Service Edge (SASE)?

Secure Access Service Edge (SASE) is a cloud architecture model that combines network security functions (such as firewalls, intrusion detection, and threat prevention) with WAN capabilities (such as SD-WAN) to support the dynamic secure access needs of organizations. SASE converges these functions into a unified, globally distributed cloud service, enabling secure and reliable access for users, applications, and devices, regardless of location. It's commonly used to improve security, reduce complexity, and enhance performance in a cloud-first world.
