SASE (Security Access Service Edge), pronounced “sassy”, is an emerging cybersecurity concept that converges networking and security functionalities into a cloud-native architecture. The term was introduced by Gartner in 2019, in response to the growing complexity of modern networks, characterized by SaaS technology and remote working models.
SASE uses strategically placed points-of-presence (PoPs) to route traffic across networks of all sizes and locations.
The SASE Security Model
The SASE Security Model consists of 5 core network and security technologies:
- Software-defined Wide Area Network (SD-WAN)
- Firewall-as a-service (FWaaS)
- Cloud Access Security Broker (CASB)
- Secure Web Gateway (SWG)
- Zero-trust Network Access (ZTNA)
