According to a study by Kroll Ontrack revealed that these employees lost company data through device malfunction or corruption.

One in five UK employees admits they save critical work data on removable devices such as flash devices.

Another seven percent of employees reported they carry around confidential work data on their own personal devices.

"One of the biggest challenges for businesses today is to understand and manage the huge quantity of data they hold," said Robert Winter, chief engineer at Kroll Ontrack. "Unfortunately, due to an increasingly mobile workforce, the risk of losing confidential data is heightened exponentially, unless the correct preventative action is taken. As a result, businesses are not only jeopardised financially but also run the risk of damaging their reputation. "

UK employees accessing work data from remote devices has risen dramatically in recent years.

Over 10 million employees now use personal tablets, laptops and other mobile devices to store work data and nearly 2 million carry work information on devices not given by their employers.

The research suggests organisations should be mindful of the privacy and security risks employees cause by storing work information on personal devices and to have a set data recovery plan in place.

"Worryingly, 7% of UK employees are carrying around confidential work data on their own mobile or handheld device which has not been supplied by their employer," said Winter. "This research clearly shows that organisations need to do much more to help protect their data. Companies must implement thorough policies and procedures to help staff understand rules and security features surrounding BYOD."
