A survey of IT staff has highlighted that smartphones are a bigger security risk than laptops.
According to endpoint data protection supplier Credant Technologies, which conducted the research, 94 percent of the IT staff surveyed claimed PDAs present a security risk, followed closely by mobile storage devices, which were identified as a worry by 88 percent.
Nearly eight in 10 said laptops were an issue. Only four in 10 had encrypted data on their laptops, and the remainder said the information was 'not worth' protecting.
A key danger with PDAs was that over half of IT executives surveyed were 'not bothering' to enter a password when they used their phone.
Nine in 10 of the smartphones were being given access to company networks without extra security, even though the phones were individually owned by users. There were no access restrictions being applied to 81 percentphones.
Credant Technologies said smartphones had become 'easy pickings' for any opportunists trying to steal them and access information.
Peter Mitteregger, European vice president at the company, said: "Companies need to regain control of these devices and the data that they are carrying, or risk finding their investment in securing the enterprise misplaced and woefully inadequate."
