Cold boxes provided a secure storage solution for important items like security keys. Gaining access to the data within a cold box necessitated physical interaction with the device and a computer connection, ensuring a secure method for safeguarding sensitive information away from network vulnerabilities exploitable by slicers.
Within the Galactic Empire, the Bureau of Ships and Services employed cold boxes for storing transponder data that was considered illegal for public knowledge. A cold box of this type was pilfered, ultimately ending up in the possession of Nebit's clan around the time of 0 BBY/0 ABY.
