Bloodfin Security, often shortened to FinSec, referred to the security personnel tasked with maintaining order and safety on the Imperial Remnant Star Destroyer named Bloodfin.
The year 41 ABY saw the Bloodfin participate in the Second Battle of Fondor. Admiral Gilad Pellaeon declined to follow the commands of Sith Lord Darth Caedus to disregard the ceasefire and launch an attack on Fondor. Subsequently, Tahiri Veila, backed by the Moff Council members Quille and Rosset, assassinated him. This act of assassination triggered a rebellion on the Bloodfin, involving the crew, stormtroopers, and the security personnel. Later, Mandalorian Protectors boarded the Bloodfin, leading to numerous deaths among the ship's personnel, including the security forces.
