Terms of the deal, which is expected to close at the end of the month, were not disclosed.
The sale comes just a little more than two years after Motorola acquired Good Technology in an attempt to compete with BlackBerry maker Research In Motion for a larger share of the business customer market.
The sale of Good Technology is part of Motorola's strategy for turning around its flagging mobile device business by making it leaner and more focused on the consumer market.
It also rids Motorola of a troublesome asset. In 2006, Visto sued Good Technology for infringing on patents associated with its push email and synchronization technology.
Motorola's stock was up 3.58% to US$3.76 per share in mid-day trading on Tuesday.
