What is SASE?
Secure access service edge, or SASE, is a cloud-based IT model that bundles software-defined networking with network security functions and delivers them from a single service provider. Gartner, a global research and advisory firm, coined the term "SASE" in 2019.
A SASE approach offers better control over and visibility into the users, traffic, and data accessing a corporate network — vital capabilities for modern, globally distributed organizations. Networks built with SASE are flexible and scalable, able to connect globally distributed employees and offices across any location and via any device.

Cloud access security broker (CASB)
A CASB performs several security functions for cloud-hosted services, including revealing shadow IT (unauthorized corporate systems), securing confidential data through access control and data loss prevention (DLP), and ensuring compliance with data privacy regulations.

Firewall-as-a-Service (FWaaS)
FWaaS refers to firewalls delivered from the cloud as a service. FWaaS protects cloud-based platforms, infrastructure, and applications from cyber attacks. Unlike traditional firewalls, FWaaS is not a physical appliance, but a set of security capabilities that includes URL filtering, intrusion prevention, and uniform policy management across all network traffic.
