Prey is an all-in-one cross-platform security solution for laptops, tablets, and phones. Its solid tracking and reporting technology helps people and organizations keep track of their assets 24/7, and proves to be crucial in the recovery of stolen devices every day.
It's free to use for up to three devices of any kind, from computers running Windows, Mac, or Linux to Android devices.
Because it's tracking software that doesn't want to be seen, Prey is almost invisible when it's running on your system, without any configuration or executable files to be seen. It quietly checks in with Prey's servers in the background, at an interval you decide, to see if the owner has logged in and marked it as stolen.
When setting up, the most important module to turn on is Geo, which uses Google's Wi-Fi location API to try and triangulate a laptop's location or the GPS chip in an Android for very accurate positioning. Android phones set up with Prey have one unique feature: SIM card protection. If a thief attempts to swap out the SIM card in your phone, the new SIM number is captured and text-messaged to a contact you set up in the Prey options.
