SecureBox Corporation (SBC), with Lawrence Livermore National Laboratory, has developed a small, ruggedized, portable container security device that travels inside a container and actively monitors for intrusion during the voyage, reporting alarms and GPS locations to remote operations centers. The company is currently commercializing this device. Features include unique 6-wall intrusion detection, GPS, storage of cargo data and handler biometrics, and multiple 2-way communications modes. Radiation, hazmat and customer-specified sensors can be added.

In contrast with existing door seals which are ineffective, and RFID solutions which require capital infrastructure and can be insecure, or simple door-open alarms, only SBC offers a self-contained, portable device with true 6-wall intrusion detection, a robust sensor suite and option cellular or satellite communications. Secure box does not require expensive reader infrastructure along shipping routes.
