SugarSync:

Another online backup and file-sharing application that offers free cloud storage and synbchornization, SugarSync allows users to share files from any devices and also allows for private file sharing through selected coupons. Another notable feature of this service is the Cloud Search function which allows users to find the content filed away in folders.

"Some file sharing and document hosting apps are perceived as a risk, and therefore blocked," Dale said of all file-sharing, document-hosting-type apps.

DropBox:

Dropbox is a file hosting service that offer users in data storing, file synchronization and other client services.

Enterprises really hate the offers provided by Dropbox as it creates a situation of data leakage or data loss. For instance consider the situation where an employee walks off to your rival company with some of the precious company data and he has Dropbox installed in his computer.

"The top concern for most corporations is knowing that their data is safe, and always in the right hands," Dale said.
