Embodiments of the present invention for determining a geo-location for a device in communication with a network service provider begin with installing a mechanism for collecting geolocation data at a client device. The mechanism may be implemented as a mobile app, client application, browser plug-in, or other mechanism. The mechanism may collect geolocation data from multiple sources, including the device itself and other devices within the vicinity. The mechanism may also collect data regarding selected programs that may be installed on the client device. The geolocation data and program data may be transmitted back to a server for processing. The server may determine whether a geolocation is acceptable by determining a geolocation from the geolocation data, a likelihood of accuracy and/or trust score, as well as determining if any undesirable programs are stored on the client device. A determination regarding the geolocation of the client device if made, a white list of devices may be updated, and the geolocation results are provided the network service provider, either directly by the server or through the mechanism on the client device.
