More than half of IT organisations handled business data on employee-owned devices.
In the midst of growing adoption of personal mobile devices at work, related BYOD security incidents have cost organisations over $250,000, according to IT executives surveyed by Check Point.
The Check Point 2014 Mobile Security Report noted that the rise in related breach costs is due to an increase in their volume and severity.
About 91% of respondents reported a rise in BYOD, with more than half of them claiming they handled business data on employee-owned devices, up from 37% in 2013.
Check Point UK managing director Keith Bird was quoted by Infosecurity as saying: "As the data shows, more and more devices are connecting to networks, and faster than security can be deployed on them, so there is a corresponding increase in mobile breaches.
"That in turn makes it more likely that a serious breach will occur, which will cost more to investigate and remediate."
Furthermore, 82% of them anticipated a rise in BYOD security incidents in the next year, while nearly all of them were concerned about the effect of a mobile security incident, with lost or stolen data being their top concern.
According to two third of respondents, Android posed a major security risk, compared to other operating systems including iOS, Windows Mobile and BlackBerry.
Bird added: "For a majority of firms it is reasonable to enforce basic security rules before a device can connect to the network, or to deploy a cloud solution that the device connects through to safeguard remote sessions.
"A secure container on devices is also desirable to separate business information and apps – corporate email and so on – from personal data."
