Forbes contributor Bob Egan says Samsung is throwing in the towel on the Knox platform. Egan: “After 18 months of going it alone and spending untold sums of money on development and marketing” The Forbes article went to print just over a month after Samsung announced that the Department of Defense had added five of their products to the Defense Information Systems Agency’s approved device list. Samsung disagreed with the Forbes article, saying they have no plans to stop development on the platform. Knox is Samsung’s answer to enterprise customer demands for stronger Android offering.”]
