DeskStream Desktop Virtualization Realities

  1. 1. cannot accommodate mobile laptop users, and they also present challenges in terms of overall end-user experience and application compatibility. On the other hand, enterprises also have growing concerns about endpoint security and data leakage. IDC analysts state that 60% of enterprise confidential information resides on the endpoints and 42% of data breaches are a result of a lost device, including laptops and mobile phones. Laptops rank first in this regard. Desktop Virtualization has to Satisfy Three Constituents: Overview instead of addressing the customer requirements.
