Having already stolen the consumer crown from Apple's iPhone, Samsung is looking to supplant BlackBerry in the business world.

To get corporate IT departments -- BlackBerry's (BBRY) last remaining stronghold -- to consider opening their gates to other mobile devices, Samsung will be padlocking its upcoming Galaxy S4 smartphone with a security solution appropriately dubbed "Knox" (like the famous fort with all the gold).

Galaxy S4 users will be able to maintain separate identities for work and play. Samsung says Knox places users' personal and work applications into separate and isolated containers, preventing malware from infiltrating the corporate network. The Galaxy S4 will be released Thursday.Though a mix of hardware and software tricks developed by the U.S. National Security Agency, Samsung claims Knox prevents important data from getting into the wrong hands.

That's a very BlackBerry-esque promise and a first for Google's (GOOG, Fortune 500) Android operating system. There are many software-based add-on security solutions for Android, but Samsung is the first to bake them right into the phone's hardware.
