Secure Access Service Edge. SASE. That’s It.
Secure access service edge (SASE) is a network architecture that rolls software-defined wide area networking (SD-WAN) and security into a cloud service that promises simplified WAN deployment, improved efficiency and security, and to provide appropriate bandwidth per application.
The WAN side of SASE relies on capabilities supplied by entities including SD-WAN providers, carriers, content-delivery networks, network-as-a-service providers, bandwidth aggregators and networking equipment vendors.
The security side relies on cloud-access security brokers, cloud secure web gateways, zero-trust network access, firewall-as-a-service, web-API-protection-as-a-service, DNS and remote browser isolation.

SASE Business Benefits
The SASE model encourages businesses to consolidate these core technologies with fewer vendors. Ideally, they would be managed from a single portal. There are numerous benefits of implementing a SASE architecture in an organization.
SASE allows organizations to attain cloud-centric technology, reduce the operational burden and cost, and improve security and reduce threats.
