Secure Access Service Edge (SASE) delivers networking and security from a cloud platform, placing controls close to users and apps. If you’re asking what is Secure Access Service Edge, it’s the model that blends SD-WAN with zero-trust security—typically ZTNA, secure web gateway, CASB, DLP, and firewall-as-a-service—so policies follow identity and context, not a fixed location.
In simple terms, SASE connects people to resources fast and safely, whether they’re in branches, at home, or on the road. We often see IT leaders adopt SASE to replace stack sprawl, standardize access for hybrid work, and secure direct-to-cloud traffic without backhauling through data centers.
Key advantages include:
- Consistent access: Identity- and device-aware policies everywhere.
- Performance: Local, cloud-delivered enforcement reduces latency.
- Zero trust by design: Minimize implicit trust and lateral movement.
- Simplified operations: One policy fabric across sites and remote users.
Our take? Treat SASE as a journey—start with clear identity, network, and data policies, then phase capabilities to avoid “big bang” risk.
