SASE (Secure Access Service Edge)
Converge networking and security into a single cloud-delivered service at the edge
What it is
SASE converges wide-area networking and network security into a single cloud-delivered service. It combines SD-WAN connectivity with cloud-delivered security functions including secure web gateway, cloud access security broker, zero trust network access, and firewall-as-a-service. Rather than backhauling traffic to a central data center for security inspection, SASE applies security policies at the edge, closest to the user, regardless of their location. This architecture is designed for organizations with distributed workforces, multiple locations, and heavy cloud application usage.
Why it matters
Traditional security architectures route all traffic through a central firewall, creating bottlenecks and latency for remote users and branch offices. SASE moves security to the cloud edge, providing consistent protection everywhere while improving performance for cloud applications.
What to expect
SASE deployment is typically phased: SD-WAN connectivity first, then layering on security services. Full deployment across a multi-location organization takes four to twelve weeks. The transition replaces multiple point products with a unified platform, simplifying management and reducing vendor complexity.

Common questions
What is the difference between SD-WAN and SASE?
SD-WAN optimizes network connectivity. SASE adds comprehensive security on top of that connectivity. Think of SD-WAN as the highway and SASE as the highway plus toll booths, cameras, and guardrails all managed from one control center.
