I am curious to know if there are any solutions out there (opensource or otherwise) that will permit an organization to strictly prevent the use of BYOD (bring your own device) for the use of email.
Access to e-mail has to be done through company phones, where IT should apply password policies on the device. If a user were to access email through a personal phone (imap. activesync), it would be difficult to control phones getting lost/stolen, and information with it. Since it's a personal device that would not get reported as lost, an employee could just purchase another one.
I know blackberries do this through BES servers, but we have users with iPhones, and android phones.
Any help would be appreciated.
