A system and method for facilitating controlled access by a client device to one or more services provided by a server are disclosed. The client device's access to the services provided by the server may be dynamically controlled by a controller, which may generate instructions to an agent to effectuate the access control. The agent may be configured to control one or more access components associated with the server. The instructions generated by the controller may instruct the agent to cause the access control components to grant or remove the client device's access to the services provided by the server. In some implementations, the controller may generate such instructions based on a status of a session established between the controller and the client device.
