A SASE architecture addresses the challenges of securing work-from-anywhere users by providing secure access and high-performance connectivity, no matter whether users are in large and small branches or other off-site locations.

SASE architecture converges SD-WAN with cloud-delivered security service edge (SSE) to provide users with secure and fast access to the internet, SaaS, and private applications from any location. SSE capabilities, including zero-trust network access (ZTNA), Firewall-as-a-Service (FWaaS), secure web gateway (SWG), and cloud access security broker (CASB), are delivered as a cloud service and enable zero-trust access based on the identity of a device or entity.

This buyer's guide details the challenges SASE solves, SASE use cases, and key requirements that you can use to build a checklist for evaluating SASE vendors.
