knox is a security implemented by samsung, it is active in the background, has no app for that. basically it "protects" samsung warranty better than the triangle in download mode witch shows how many imes you flashed, if you had roted ur device, in download mode will show u have 0x1 warranty voided.<---- thats basically KNOX.

KNOX is a security container -> a place where you install apps inside a secure container that cannot be tampered with on a high level TrustZone security algorithm.
It's great that the person above said what it essentially does to your device, but what he explained above is what happens when the TrustZone between the software and the hardware is breached during root/downgrade/unsigned flashing. This essentially would allow the viewer of the KNOX status to know
when the device does not trust it's own body with secure enterprise level apps (Application Integrity), hence the KNOX warranty bit will be set from 0x0 to 0x1 meaning "I will not ever run a secure container anymore".
You won't find KNOX 2.0 on your device as this is now a paid service for enterprises at a rate of $3.60 and it is only set up on your device when you have the KNOX 2.0 kit deployed on your device, unlike KNOX 1.0 where you get to enter KNOX mode anytime you want.
