A system and method for hardware tamper detection and mitigation for a circuit breaker. The method includes detecting and mitigating a breach to a circuit breaker of an electrical power management system, wherein the circuit breaker includes a housing, an electrical circuit, and switch coupled to and controllable by the electrical circuit. An alert identifying a detected breach event at the circuit breaker is generated and transmitted to a computing device. The circuit breaker device experiencing the detected breach event is disabled in response to the alert. An electrical power management system includes a plurality of circuit breakers each having a breach detector coupled to an electrical circuit, and a switch coupled to and controllable by the electrical circuit. A circuit breaker controller controls the state of the circuit breaker as determined by the breach detector.
