What does SASE stand for?

SASE stands for Secure Access Services Edge. The term was coined by market research firm Gartner, which defines SASE as cloud-based and service-oriented. It brings together various technologies (including SD-WAN, NGFW, CASB, SWG, ZTNA) to respond to changing working conditions.

Cloud-based services and increasingly mobile users require different approaches to maintain a high level of security across the board.
