Zscaler VNFs

Zscaler is available as the App Connector and Private Service Edge for zero-trust private access, managed through the Zscaler admin portal. These VNFs are offered customer-managed under your Zscaler subscription. Each device is offered customer-managed, Tata Communications-managed, or both. Sizes, interfaces, access methods and supported versions are below, with links to Zscaler’s own documentation and support.

Licensing and management

Devices from Zscaler are offered under two models. With customer-managed (BYOL), Tata Communications hosts the VNF and you provide and manage your own Zscaler licence, configuration and patching; you are responsible for obtaining a valid Zscaler licence, so contact Zscaler or a Zscaler partner to purchase a licence and support contract. With Tata Communications-managed, Tata Communications provides the licence (subscription) and runs configuration, management, patching and renewals.

Deploying with or without a public IP address

A VNF can be deployed with a public IP address on IZO™+ Multi Cloud Connect or without one; where no public IP is assigned, plan management access over the private path in your solution. Device-side configuration (interfaces, routing, policy) is performed in the vendor’s own management tooling using the access methods listed for each device. This page stays at parameter-handoff level and does not reproduce vendor command-line configuration; see the vendor documentation below.

Zscaler documentation and support

For device configuration, feature detail and throughput figures, use Zscaler’s own resources. For a customer-managed device you obtain support from Zscaler or a Zscaler partner; for a Tata Communications-managed device, raise a request on the TCx Portal and Tata Communications handles it.
