The present disclosure describes use of two security processors for a mobile device. In some aspects, a first security processor device embodied in a security component of an apparatus receives a user input via an input device and transmits a security condition signal to a second security processor device embodied in a System on Chip (SoC) component of the apparatus, causing the SoC component to perform a security operation. In other aspects, the first security processor receives a signal via a sensor device sensing environmental conditions surrounding the apparatus and, in response, transmits a security condition signal to the second security processor, causing the SoC component to perform a security operation. The security operation is directly controlled, maintained, and implemented by the second security processor embodied in the SoC component.
