# Engine Editor > Add-Ons > ZTNA Connector

From 7.0 version onwards, ZTNA Connector is integrated with engine.

This dialog box is used to enable the ZTNA connector so that, the connector is downloaded and installed automatically to the Engine. The Engine can be used as a connection point for applications that you might want to publish through FONE portal by using Forcepoint Network Security Platform as ZTNA connector. For more information about the ZTNA connector, see Zero Trust Network Access section in Forcepoint ONE Admin Guide.
