Board of Directors Portals. Sometimes integrated with Legal Entity Management, but often standalone, these highly secure portals aim to provide a necessarily easy method for a company's directors to access sensitive documents and materials related to their board and committee appointments. More sophisticated offerings provide calendaring functions, a virtual "chat room", and company contact information. Strong security is invariably a key driver in board portal selections, with transmission encryption and digital rights management often on the evaluation checklist for IT (and increasingly the directors themselves). This is becoming even more critical with the proliferation of portals that can be accessed via mobile apps and tablet based user interfaces.
