Show full answer Show less ## Key Features * **Private Connectivity for Zero Copy Connectors (Australia Release)**: Enables secure connections to data sources hosted in private cloud or on-premises environments without exposing credentials or IP addresses. The Reverse Tunnel gateway routes encrypted traffic via private relays without decrypting it, enhancing security. * **Private Relay Deployment**: Customers can deploy a private relay within their network that establishes outbound encrypted connections to the Reverse Tunnel gateway. This relay operates similarly to a MID Server with automatic authentication, simplifying setup and management. * **Relay Heartbeat Monitoring**: Allows monitoring of relay status and health directly from the relay record in the ServiceNow instance, improving operational visibility. * **Service Endpoint Management**: Customers can register fully qualified domain names (FQDN) and port numbers for each data source connected to the relay. This ensures accurate routing of incoming traffic through the gateway to the correct relay. ## Upgrade and Activation Information No new updates or changes were introduced in the Brazil release for Reverse Tunnel. Prior releases, specifically Australia, introduced the core features mentioned above. **Activation:** Reverse Tunnel is available as the Zero Copy Reverse Tunnel store app (snzctunnel) in the ServiceNow Store. Customers should refer to the app documentation to connect private relays to the Reverse Tunnel gateway and activate the product accordingly. ## Additional Notes * No features were removed or deprecated between Zurich and Brazil releases. * There are no new changes to browser requirements, accessibility, localization, or other additional requirements across these releases. * Important preparation for upgrade includes reviewing pre- and post-upgrade tasks, although no specific Brazil release tasks were noted. ## Practical Impact for ServiceNow Customers By upgrading to the Brazil release (via Australia), customers gain enhanced secure connectivity capabilities for integrating private cloud and on-premises data sources without exposing sensitive network information or opening inbound firewall ports. The deployment of private relays and heartbeat monitoring improves security posture and management efficiency. Activation through the ServiceNow Store app ensures a streamlined setup process.
