It is headquartered in Teaneck, New Jersey, United States. Cognizant is part of the NASDAQ-100 and trades under CTSH. It was founded as an in-house technology unit of Dun & Bradstreet in 1994, and started serving external clients in 1996.
After a series of corporate re-organisations there was an initial public offering in 1998.
