What is Secure Access Service Edge?

Quick answer

A cloud-based approach, known as SASE, that combines networking and security services so users connect safely from anywhere.

Secure Access Service Edge, explained

The term SASE was introduced by the research firm Gartner in 2019. Instead of routing all traffic back through a company's data center for inspection, SASE delivers security functions such as secure web gateways, cloud access security, firewall as a service, and zero trust network access from cloud locations close to users. These are combined with software-defined networking that routes traffic efficiently.

For example, a company with staff working from home and several branch offices can use a SASE service so every employee's connection to cloud apps and internal systems passes through the same security policies, wherever they are. SASE supports zero trust principles and can replace or reduce traditional VPNs. Adopting it is usually a gradual process, and organizations should avoid locking into one vendor without checking integration and performance.
