Daon (pronounced day-on) is an international biometrics and identity assurance software company founded in 1999 by Irish entrepreneur Dermot Desmond. The name, Daon, was chosen because it stems from the Celtic word for human being, duine daonna. Daon is headquartered just miles outside of Washington, DC in Fairfax, VA. Daon also has major operations in Dublin, located in the International Financial Services Center (IFSC). It has an additional office in Canberra, Australia.
