Determining on-net/off-net status of a client device

摘要

Systems and methods are described for determining an on-net/off-set status of a client device. An endpoint security program running on the client device maintains an enterprise public Internet Protocol (IP) list containing one or more ranges of public IP addresses associated with an enterprise network. Further, the endpoint security program sends a request to a cloud-based service for information regarding a public IP address of the client device. In response to the request, the endpoint security program receives from the cloud-based service a response containing the public IP address and determines a connection status of the client device with respect to the enterprise network by comparing the public IP address to the enterprise public IP list.
