A method of providing content to a user is disclosed, the method comprising receiving a first content object (2003) from a content provider (2010), the first content object being packaged with metadata (2005) and a first rule, using the metadata (2005) to assign the first content object (2003) to a content class, packaging the first content object (2003) in a secure container (2002), wherein the first rule is associated with the secure container (2002), associating a second rule with the secure container (2002), and communicating the secure container (2002) to a protected processing environment (154) associated with a user, the communicating being a function, at least in part, of a match between the content class and a user class to which the user has been assigned. The protected processing environment is operable to open the secure container (2002) to retrieve at least a portion of the first content object (2003) and to use at least a portion of the first content object (2003), the opening being a function, at least in part, of at least one of the first rule and the second rule, and the using being a function, at least in part, of the first rule and the second rule.
