SASE concepts
SASE concept briefs explain the ideas that shape a Secure Access Service Edge (SASE) architecture. Zero Trust is the security model SASE puts into practice: no user or device is trusted by default, and every session is verified.
Security Service Edge (SSE) is the security half of SASE without the networking layer. Many organizations adopt SSE first, as a step toward full SASE.
- ConceptSASE ArchitectureSASE architecture explained: its layers, how traffic flows, and the four models (cloud-native, hybrid, self-hosted, distributed), and how to choose.
- ConceptZero Trust & SASEZero Trust SASE explained: how a SASE architecture delivers the Zero Trust model, enforcing identity-based, least-privilege access on every session for every user and device.
- ConceptSASE & SSESASE vs SSE explained: Security Service Edge is the security half of SASE without SD-WAN. Compare their components, differences, use cases, and the migration path to full SASE.
