In one example of federated mobile device management, a first management server federates with a second management server based on an exchange of one or more identity authentication certificates between them. After the first and second management servers have federated or affiliated, they can exchange mobile device management data, including compliance policies, rules, resources, etc., with each other. Based on a request from a client device for affiliated mobile device management, the first management server can request and receive device management data from the second management device. The first management server can evaluate the device management data received from the second management device for conformity with a baseline management policy. If it conforms, the first management server can use the device management data from the second management server, at least in part, to manage the client device.
