Simple definition
SSE combines cloud-delivered security services that control access to the web, SaaS services and private applications.
Purpose and use
It aims to apply consistent policies for users across offices and remote-working locations.
How does it work?
It generally combines secure web gateway, cloud access security and Zero Trust access capabilities. Decisions can consider identity, device and requested resource.
Key points
- Example: an authorized user on a compliant device receives access to a private application without access to the entire network.
- Check covered traffic, exceptions, logs and application impact before broad deployment.
Points to watch
SSE supplies security capabilities; SASE combines them with wide-area networking. Service availability and latency still require assessment.
In short
SSE brings access control closer to distributed users and applications through cloud security services.
