What fictional company operates the Animus in the modern-day story of Assassin's Creed?

Abstergo Industries operates the Animus in Assassin's Creed's modern-day story.

Abstergo is a powerful fictional corporation secretly controlled by the modern Templar Order. Its research includes the Animus, a machine that allows a subject to access genetic memories inherited from ancestors. In the first game, Abstergo forces Desmond Miles to relive Altaïr's memories as part of a project intended to locate powerful Pieces of Eden.

The company publicly presents itself as a multinational corporation involved in pharmaceuticals, technology, and other industries. This public identity helps conceal its Templar activities and gives the modern conflict a corporate setting rather than a purely medieval one.

Abstergo's Animus technology changes across the series. Later games show commercialized forms such as the Helix entertainment platform, allowing customers to experience reconstructed memories. Helix is a product and platform associated with Abstergo, not the name of the corporation itself. The Assassin organization opposing Abstergo is the modern continuation of the Hidden Ones.
