The Zürich Security Forces, or ZSF, alternatively known as the Zürich Defense Force, is a private security force that appears in Call of Duty: Black Ops III.

Tasked with defending the city of Zürich from an influx of anti-technological terrorist attacks aimed at the controversial Coalescence Corporation, the Zürich Security Forces are reportedly a reputable force with a large amount of funding; they possess state-of-the-art drones, walkers, and GI Units. However, in-game they are portrayed as inefficient and inept in their handling of terrorist attacks, failing to stop Xavier Hirtzel and allowing the Coalescence Headquarters to be infiltrated by Jacob Hendricks.
