Traditionally, IT departments could build a wall and dig a moat around company data and keep it inside the network. But as society and business get more mobile and find real-time access to data becomes more important, it is increasingly common for a variety of devices – both company-owned and personal – to seek access to important data.
That makes security a much bigger job because the security postures of those outside devices and networks aren't always known. But it may not be practical to limit access to only company assets inside of the company network. Many companies are looking at mobile device management (MDM) solutions to provide controlled access to company data on personal devices. These solutions also give companies a way to "wipe" the company data from the personal device in the event it is lost, stolen or if the employee leaves your company.
