An exemplary apparatus includes one or more processors, volatile memory, a storage drive and circuitry configured to establish a network connection and to attempt to send credentials via an established network connection. Such an apparatus further includes circuitry configured, responsive to authentication failure after an attempt to send credentials, to release an implemented security policy and load an operating system stored on the storage drive, and, responsive to an attempt to send credentials, to maintain an implemented security policy and to use an operating system exposed via an established network connection and associated with the sent credentials Such an apparatus optionally includes circuitry configured to implement a security policy that isolates at least a portion of a local storage drive. Various other apparatuses, systems, methods, etc., are also disclosed.
