The popularity of mobile working continues to grow in the UK, but many firms are still concerned about the security implications of investing in mobile devices for employees, according to new research released by Sony Ericsson. The survey found that over half of the workforce now works away from the office at some point during the week and a further half said that this had increased in the last year.

However, while 82 percent of medium and large enterprises said they are prepared to invest in mobile devices for their staff to improve productivity, efficiency and employee motivation, roughly the same percentage said they have data and security concerns.
