Yes it is. At the software level: It uses an advanced container technology where every app is contained in its own respective place and any access to resources or calls to system is monitored by TZMA Agent. At hardware level: Data stored is highly encrypted through a device specific key, the security of which is entrusted upon TZMA and an e-fuse, where any attempt to access data through any kind of flashing/tampering results in tripping of Knox Validity counter and forfeiture of any access to the key hence the data now remains inaccessible
