How the Zscaler Client Connector Works
The Zscaler Client Connector operates as a lightweight application installed on the user’s device (laptop, desktop, or mobile device). Here’s a simplified breakdown of the process:
- User Authentication: The user authenticates with the Zscaler service, typically using existing corporate credentials.
- Secure Tunnel Creation: The Client Connector establishes a secure tunnel (usually over HTTPS) to the closest Zscaler enforcement node.
- Traffic Routing: All internet traffic from the device (or a subset defined by policy) is routed through the secure tunnel to the Zscaler cloud.
- Security Inspection: The Zscaler cloud inspects the traffic for threats, enforces security policies, and applies appropriate security controls.
- Application Access: Approved traffic is forwarded to the destination application or resource, while unauthorized traffic is blocked.
