Which fictional corporation controls the Animus technology in the modern-day storyline of Assassin's Creed?

Abstergo Industries is the fictional corporation that controls the Animus technology in Assassin's Creed's modern-day storyline.

Abstergo is presented as a powerful multinational corporation linked to the modern Templar Order. Its Animus technology allows users to experience genetic memories inherited through their ancestry, creating the framework for the series' historical settings. The corporation's public business activities conceal its deeper role in the long conflict with the Assassins.

The name is easy to confuse with the Animus itself. The Animus is the machine or system used to access memories, while Abstergo Industries is the organization that develops and operates the technology in the modern narrative. The Assassin-controlled organisation known as the Assassin Brotherhood is its principal opposing force.

Abstergo appears throughout the franchise, although the identity of the modern-day user and the exact interface change between games. Its presence links otherwise separate historical stories into one continuing science-fiction plot.
