Citrix has entered into an agreement to buy Zenprise, a mobile device management (MDM) software vendor. The deal is expected to close in the first quarter of 2013. Citrix said the integration of Zenprise’s software will enable it to manage mobile devices, applications and data from a single, integrated product line. Analyst: Citrix acquisition marks “the beginning of the end for stand alone MDM vendors. More acquisitions will come and those left behind will fade away longer term””]
