DefStat

Upon the activation of a DefStat Three warning, the stormtroopers of the Vault security contingent immediately responded.

DefStat was a layered security warning system utilized within Imperial facilities, for example, the research complex located on Scarif. A DefStat Three warning indicated that an intrusion was happening. When Jyn Erso alongside Cassian Andor gained access to the complex's vault, that specific alert was triggered.
