Secure Access Service Edge

Secure Access Service Edge (SASE) is a cloud-native architecture that combines network security and wide-area networking (WAN) capabilities into a unified service delivered from the cloud. It integrates technologies like secure web gateways, cloud access security brokers, firewall-as-a-service, and zero-trust network access to provide secure access to applications and data regardless of user location. This model shifts security from traditional data center perimeters to a distributed, identity-centric approach.

Also known as: SASE, Secure Access Service Edge (SASE), SASE framework, Cloud-native security platform, Network security as a service

Why learn Secure Access Service Edge?

Developers should learn SASE when building or maintaining applications in hybrid or multi-cloud environments, as it ensures secure, consistent access for remote users and devices. It's particularly valuable for organizations adopting zero-trust security models, enabling secure access to cloud applications without backhauling traffic through corporate networks. Use cases include securing remote workforces, protecting cloud-native applications, and simplifying network security management in distributed IT infrastructures.
