Technically heavily modified R-series astromech droids, especially R1 and R2 units, SB-20s retain the original units outer shell so as to appear to be ordinary legal droids, but have been massively overhauled with highly illegal espionage and encryption/decryption gear and programming internally.
Capable of slicing through systems and retrieving data with very little chance of detection due to their SecurityViolator security programming and CodeRifter Encryption Equipment, SB-20s were made all the more dangerous by their nondescript appearance - generally allowing them easy access to sensitive computers and free passage through security checkpoints.
Marketed quietly to underground groups at a base price of around twelve thousand credits, the SB-20 was illegal throughout the Galactic Empire. Despite this, Imperial Intelligence acquired some of these droids for their own purposes; with one such droid being instrumental in gathering information before the Imperial attack on a Rebel base on Pkihantri.
