iManage is line of enterprise information management products including document management and records management.
iManage is best understood as a product line. Much as Microsoft has a line of "Office" products, iManage (formerly owned by Autonomy, a branch of Hewlett-Packard) has a line of products. A full list of these products can be found here: https://imanage.com/products-solutions/
One of the more commonly used iManage products is Work (formerly known as Worksite/FileSite), an enterprise Document Management System (DMS) used in a large number of financial and legal services firms. However, questions concerning FileSite should use both an "iManage" tag and a "FileSite" tag to help clarify the subject of the question.
