Disclosed are various embodiments for systems and methods for controlling access of networks. In one embodiment, an access control service receives requests to access network beacons from client devices. In response, the access control service determines whether the client devices satisfy authorization rules associated with the network beacons. If the access control service determines that the client devices satisfy the authorization rules associated with the network beacons, the access control service authorizes the client devices to access the network beacons. Subsequently, if the client devices cease to satisfy the authorization rules associated with the network beacons, the access control service terminates the authorization of the client devices to access the network beacons.
