A trusted execution environment on an enterprise-enabled computing device allows invocation of a suite of secure applications (apps) on a computing device in an enterprise without hindering external or non-enterprise apps from running on in the same memory space on the same enterprise computing device. An application wrapper provides an operation queue for storing application lifecycle operations while the trusted execution environment is enabled, and the environment is secured. The application defers lifecycle operation to ensure that all security measures are in place before it is allowed to execute. The operation queue receives entries corresponding to the application lifecycle events, and suspends process execution of the lifecycle operations until the secure environment is ready for the operation queued events to be executed.
