Improved system and approaches for permitting users of different organizations to access secured files (e.g., documents) are disclosed. These users can be part of a group that is shared across a plurality of file security systems. For example, at a first file security system, a user of the shared group can secure a file for restricted access by those users within the shared group. Subsequently, at a different file security system, another user of the shared group is able to access the content of the secured file.
