In order to enforce the Cabinet Office HR 'Appropriate Usage Policy' for our IT systems we additionally use the website blocking system Websense Web Filter. Websense Inc. is an associate member of the Internet Web Foundation (IWF). The Websense Web Filter provides a list of categories to be blocked and URLs of sites within the category are updated on a daily basis.
Each Government Department is responsible for setting, implementing and maintaining its own controls. The Cabinet Office does not keep information centrally about the controls applied in other Departments.
