  • Feature in Limited Availability
    • Extranet Application Support

      To access Extranet Application Support, contact your Zscaler Account team.

      Zscaler Extranet Application Support provides organizations with a secure way to access resources from partners that are not using the Zscaler service. This is typically accomplished with site-to-site VPN tunnels which present organizational, financial, and security drawbacks. Zscaler Extranet Application Support provides access to partner resources through IPSec tunnels, retaining the benefits of the Zscaler Zero Trust Exchange (ZTE) without requiring partners to install hardware and software.

      Extranet resources are created on the Extranet page. Each resource is configured with one or more traffic selectors and DNS servers.

      Extranet resources must be assigned to locations in order to grant users access to the partner resource. Extranet is available as a Location Type when configuring locations.

      Selecting Extranet as the Location type prompts the user to select an Extranet Resource, Traffic Selector, and DNS Server.

      After extranet locations are configured in the ZIA Admin Portal, they become available in the ZPA Admin Portal when configuring server groups and application segments. You can configure ZPA access policies to manage extranet applications.

      To learn more about Extranet Application Support, see Understanding Extranet Application Support, About Extranet, and Configuring an Extranet. Ranges and limitations for Extranet Application Support are listed on Ranges & Limitations.

      Extranet Insights

      With the new Extranet Insights (Analytics > Extranet Insights), you can view IPSec tunnel data, as well as monitor the health and status of your configured extranets.

      To learn more about Extranet Insights, see About Insights, About Insights Logs, Extranet Insights Logs: Columns, and Extranet Insights Logs: Filters.

      Tunnel Insights Logs

      A filter and column, Extranet Name, is added to Tunnel Insights Logs.

      To learn more, see Tunnel Insights Logs: Columns and Tunnel Insights Logs: Filters.

      NSS Feeds

      When configuring an NSS or Cloud NSS feed for Tunnel logs, you can select Extranet in the Tunnel Type filter to limit the logs based on this tunnel type.

      To learn more, see Adding NSS Feeds for Tunnel Logs and Adding Cloud NSS Feeds for Tunnel Logs.

      Update to Cloud Service API

      The cloud service API includes new endpoints to configure and manage extranet resources. The following endpoints are introduced to retrieve the list of configured extranet resources and add, modify, and delete extranet resources:

      • GET /extranet
      • POST /extranet
      • PUT /extranet
      • GET /extranet/lite
      • GET /extranet/{id}
      • DELETE /extranet/{id}

      In addition, the following attributes are added to the Location model to assign an extranet to a location:

      • extranet
      • extranetIpPool
      • extranetDns
      • defaultExtranetTsPool
      • defaultExtranetDns
