Abstract: A remote access client is provided for enabling communication between a remote data terminal configured to access a public network, and an enterprise network by way of a VPN tunnel through the public network. The remote access client includes at least one application program interface (API) to receive a first verification of the operating state of a predetermined application of the remote data terminal to enable a connection agent for establishing a point of presence on the public network. Upon connection to the point of presence, the API exchanges data between the remote access client and the predetermined application of the remote data terminal. The remote access client receives a second periodic verification of the operating state of the predetermined application via the API for terminating the connection to the point of presence upon the absence of the second verification.
