Google Drive:

Next on the list of the most hated apps by enterprises is Google Drive. Similar to SkyDrive, Google Drive is file storage, synchronization cloud service that allows users to edit, create and share documents, spreadsheets, presentations and photos as well as "pin" files for offline use later. Although Google is well known for its security within its services, enterprises feel that the Google Drive still is a cloud application that is vulnerable to outages and hacks.

"IT admins might feel more secure dealing with OS manufacturers compared to some of the independent ones, but it's not a general statement of 'one is more secure than the other,'" Dale said.

BoxNet:

BoxNet works the same as SkyDrive and Google Drive, except it’s a third party data sharing cloud service. The service allows users to store files, from documents to presentations, in the cloud, allowing them to sync, edit and wirelessly stream and print stored files on the go. Apart from this, the app also allows data encryption and virtual hosting, which is always a concern for corporate.

"Six out of the 10 blacklisted apps are cloud applications because cloud sharing is and could be a direct risk to corporate data," Dale said.
