Which company operates the Animus and serves as a major modern antagonist in Assassin's Creed?

Abstergo Industries operates the Animus and serves as a major modern antagonist in Assassin's Creed.

Abstergo is a vast modern corporation secretly controlled by the Templar Order. In the first game, its researchers use Desmond Miles to access Altaïr's genetic memories. The company publicly presents itself as a powerful multinational organization involved in fields such as pharmaceuticals, technology, and entertainment.

Its conflict with the Assassin Brotherhood gives the series a contemporary counterpart to the historical Templar-Assassin struggle. Abstergo seeks useful information from ancestral memories, including knowledge connected to powerful ancient artifacts.

A common confusion is treating Abstergo as simply a software company because of its Animus research. The organization is much broader in the fiction, with corporate divisions, research programs, security operations, and later consumer-facing products such as the Helix entertainment platform.
