Almost two-thirds (65 per cent) of businesses believe employees are not accessing corporate data on personal devices, when in fact 42 per cent are doing so without permission.

According to research by Juniper, among 4,037 mobile device users and IT decision-makers in the US, UK, Germany, Japan and China, 90 per cent are accessing sensitive corporate data from mobile devices, while 24 per cent of European companies said they have experienced a security breach as a result of personal mobile devices accessing their data.

It also found that the trend toward a bring-your-own-device (BYOD) policy is creating new concerns for IT leaders. Paul Gainham, senior director of solutions at Juniper, admitted that there are "no rights and wrongs" in this area, but said there was a trust gap – a willingness to embrace mobile devices alongside a lack of understanding of the security challenges.

“Businesses need to focus on mobile data management rather than device management, and on the security and management of the data and how secure it is and how easy it is to manage the critical aspects of this trend,” he said.

“There needs to be trust in mobility: only 15 per cent had a great deal of confidence, 18 per cent had very little confidence and 63 per cent were not sure. We found that 84 per cent of respondents would stop banking online if they experienced a security issue until trust was restored.”

Only 20 per cent of UK respondents had a great deal of confidence in the security of their mobile devices and services, while 60 per cent were at a crossroads and did not know if their mobile experiences were secure.

Dan Hoffman, chief mobile security evangelist at Juniper Networks, said: “Building trust in mobility is just as important as building great networks and powerful applications. Creating a safer, more secure and trusted mobile experience requires a sustained, collective effort by mobile service providers, device manufacturers, software developers, networking companies and security experts.”

Juniper Networks announced last week that it is extending its Simply Connected portfolio to that simplify and secure mobile device access to enterprise networks. It said that with new unified policy enforcement that is simplified and automated, IT managers can now set and automatically enforce consistent security and access policies across every wired, wireless and mobile connection from company-issued, personal and guest devices.

It also said that this new approach will ultimately reduce the burden on IT managers who struggle with bring your own device (BYOD) administration and security enforcement access policies.
