Secure Access Service Edge (SASE) is a modern cybersecurity framework that merges network security functions, such as firewalls and secure web gateways, with wide-area networking (WAN) capabilities. Delivered primarily as a cloud-based service, SASE enables organizations to protect users, devices, and data regardless of location. This approach is especially valuable as more people work remotely, ensuring secure and efficient access to applications and resources over the internet while simplifying management and reducing costs.
