WorkBook: A Secure Corporate Overlay for Facebook

WorkBook allows employees to securely interact with their peers using the hugely-popular Facebook service. WorkBook combines all the capabilities of Facebook with all the controls of a corporate environment, including integration with existing enterprise security services and information sources. With WorkBook, employees can find and stay in touch with corporate colleagues, publish company-related news, create bookmarks to enterprise application data and securely share the bookmarks with authorized colleagues, update on status change and get general company news. Employees can freely use Facebook, with the WorkBook overlay, with no danger of information leaking outside the organization or access being granted to unauthorized personnel.

It is after 7pm on a Friday night, so I don’t have any comments to make at this time.
