Which fictional corporation secretly represents the Templars in Assassin's Creed?

Abstergo Industries is the fictional corporation that secretly represents the Templars in Assassin's Creed.

Abstergo is introduced as a powerful modern company that conducts research with the Animus. Its public business activities conceal the continuing influence of the Templar Order, which seeks control and stability through authority over society.

In the first game, Abstergo holds Desmond Miles and forces him to relive ancestral memories. The company therefore links the historical missions to the modern-day conflict. Later games reveal that Abstergo operates in pharmaceuticals, media, technology, and entertainment, extending Templar influence beyond the laboratory.

Abstergo can be confused with the Assassin Brotherhood, which is the opposing organization, or with the fictional Helix entertainment platform associated with Abstergo Entertainment. The corporation itself is Abstergo Industries, while Abstergo Entertainment is one of its subsidiaries.
