That's a record nearly as poor as the general public's: in the UK, Credan reports, 40% of all mobile phone users go without password protection.
I doubt that the figures are much better here.
Other findings from the Credant survey of phone use among IT professionals:
80% stored business names and addresses on their devices
66% stored personal names and addresses
23% had business emails on their phones
16% of the professionals' phones held personal emails
12% had bank account details on their phones
12% had a business diary with details of all their appointments and meetings
5% had credit card information stored on a phone
1% stored passwords and PIN numbers on their phones!
Credant's respondents indicated that sales professionals were the worst at leaving data on unsecured phones, while HR professionals tended to be the most secure, probably because of the large liability HR carries if confidential employee data is exposed.
Might be a good idea to run a survey of your own staff -- and not just your IT staff --to find out a) what business information they have on their phones and b) how well protected that data is.
It is, after all, the data that's on phones and mobile devices that makes them hot commodities on the crime circuit, not the devices themselves.
