Distributed enforcement of browser rules

Various systems and methods distribute enforcement of browser rules. For example, one method can involve receiving, from a browser control client, information indicating that a user is accessing the Internet via a browser. The information received from the client can include a login name submitted by the user via the browser. The browser is installed on a computing device, and the browser control client is also installed on the computing device. The method can then send, to the browser control client, a set of one or more browser rules associated with the login name for enforcement on the computing device, in response to receipt of the information.
