OK, so how many of you have downloaded Pokemon Go on to your work phone? Come on, admit it.

　　If you were surprised the IT department let you do this, don't be - many companies have absolutely no idea what their staff are up to it seems.

　　For example, when cybersecurity firm Imperva asked one of its banking clients how many apps it thought its staff were using, the firm estimated between 75 and 100 in total. The figure was actually closer to 800.

　　Why does this matter?

　　Cloud-based apps often gain access to the camera, location, data and contacts on your phone. So you never know how much sensitive company information they may be snaffling.

　　We could be giving hackers, fraudsters and spies the keys to our company's back door, particularly if we naively use the same log-in details for external apps as we do for internal work apps.

　　"It's a mission-critical problem if you don't know which third-party apps have access to your data," says Ryan Kalember, senior vice president of cybersecurity strategy at Proofpoint.

　　This year alone tech companies such as LinkedIn, MySpace and Dropbox have suffered major data breaches, with security research company Ponemon putting the average cost per breach at $4m (£3.2m), or $158 per stolen record.

　　And our cavalier attitude to apps at work could be contributing to the problem, experts warn.

　　"If the enterprise doesn't provide the users with the tools they expect to do the job, they'll find the tools themselves," says Jon Huberman, chief executive of file-sharing company Syncplicity.

　　"But it's a huge issue for the company - data leakage is a big problem."

　　'Skeleton in the closet'

　　While apps such as Slack, Evernote, WhatsApp, and Dropbox, can help us do our jobs more efficiently - in the office and away from it - we often don't know if they've been approved by our IT departments or how much corporate data we may be sharing - wittingly or unwittingly - with the cloud.

　　Terry Ray, Imperva's chief product strategist, says: "Staff often don't think about security or know what is or isn't sensitive data.

　　"And the risks of a data breach are massively exacerbated by the cloud, even though cloud-based apps, such as Microsoft's Office 365, are proving increasingly popular because they dramatically reduce IT costs."
