The Shadow Security Droid represented a security droid model created and employed by the forces of the Galactic Empire.
These Shadow Security Droids were compact, hovering droids with a black exterior. They housed a distinctive and highly specialized droid brain. This brain contained a living being's consciousness, transferred into the droid using a dark side method. These droids posed a significant threat, equipped with heavy repeating blasters. They utilized red-colored diodes for targeting purposes.
The Shadow Security Droids were among the initial experiments conducted by the Empire. They served as an early design that led to the development of the significantly larger Shadow Droids.
Several Shadow Security Droids saw deployment on a Golan space defense platform situated within the Beshqek system. During the Battle of Byss, a quartet of these droids engaged a team of Alderaanian Resistance operatives who had boarded the platform.
