SaaS applications continue to provide a tremendous value to end users with easy setup and collaboration capabilities that are changing the way organizations do business. The concern over the loss of control of data leaving the corporate network and opening the network to external threats through unknown collaborators has caused many organizations to take a wait and see approach to SaaS. Microsoft® Office 365™ changes all that. Now SaaS services come with the application that many consider the most indispensable tool in business today: Microsoft Office. This pushes SaaS security to the forefront of most organizations and means it can no longer be ignored.
