What Is SASE? Encryption, Firewall, and More Built Into the Network

What is SASE?

Secure Access Service Edge (SASE) is a new cloud-delivered service that combines networking, security, and vast area network (WAN) capabilities. It allows organizations to deploy networks securely to support the needs of hybrid and distributed environments.

SASE extends networking and security capabilities beyond what is ordinarily available. It gives users access to a variety of threat detection capabilities, including Firewall as a Service (FWaaS), Secure Web Gateway (SWG), and Zero Trust Network Access (ZTNA). Its networking capabilities are based on software-defined WAN (SD-WAN), which allows organizations to configure networks programmatically on top of standardized network equipment.

The need for SASE

In the modern enterprise, network traffic is not confined to the on-premise data center. Many traffic and data flows occur in other locations, including cloud data centers, branch offices, internet of Things (IoT) devices, and remote workers accessing systems over public networks. Most of these remote connections occurred through virtual private networks (VPN).
