SASE (Secure Access Service Edge)
A cloud architecture combining network and security services into a unified, globally distributed platform for secure access anywhere.
What is SASE?
Secure Access Service Edge (SASE) is a cloud architecture that combines network connectivity (SD-WAN) with cloud-native security services. Pronounced "sassy," SASE delivers both capabilities as a unified cloud service, securing access regardless of user or resource location.
SASE Components
Network Services:
- SD-WAN
- WAN optimization
- Bandwidth aggregation
- Global connectivity
Security Services:
- Secure Web Gateway (SWG)
- Cloud Access Security Broker (CASB)
- Zero Trust Network Access (ZTNA)
- Firewall as a Service (FWaaS)
How SASE Works
SASE routes all traffic through cloud points of presence (PoPs) where security policies are applied consistently. Users connect to the nearest PoP, which handles both security inspection and optimal routing to destinations.
Benefits
- Simplified architecture (single vendor/platform)
- Consistent security everywhere
- Reduced complexity and costs
- Support for remote/hybrid work
- Improved performance and user experience
