Around 18% store corporate email passwords.
Only 11% of those using personal devices for work purposes are concerned about keeping work related information safe.
According to a survey, jointly conducted by Kaspersky Lab and B2B International, 36% of respondents belonging to large and medium-sized companies stored work files on their personal devices, while 34% kept work-related emails in their own devices.
What could be more alluring for hackers, 18% of the users stored passwords to corporate emails, and 11% stored networks or VPNs which can do huge damage to the organisation if hacked.
Kaspersky Lab suggests that businesses should integrate BYOD into the IT infrastructure in a responsible manner.
The company said that the integration must be done prior to allowing employees to bring their devices, and the steps must include infrastructure audit, a design stage and a pilot implementation.
Kaspersky emphasised upon the creation of a comprehensive solution across the corporate network to ensure security.
The security service provider also highlighted that companies should hire qualified IT security specialists, who will be able to provide centralised management for all mobile devices within the corporate network.
It added that companies need to come up with a rapid procedure to remove confidential corporate data from devices if they are stolen or the employee leaves the company.
Kaspersky Lab UK general manger Kirill Slavin said: "By successfully creating and managing a BYOD network, businesses can simplify their IT operations while providing greater flexibility for employees.
"The best way to make BYOD work for a business is to ensure it is simple to control and easy to maintain without compromising security or performance."
