Gregory Rattray is a nonresident senior fellow with the Cyber Statecraft Initiative at the Brent Scowcroft Center on International Security.

He is also a partner at Delta Risk, where he brings an exceptional record in establishing strategies for cyber security across both the government and private sectors. During his twenty-three-year Air Force career, he served as the director for Cyber Security on the National Security Council staff in the White House, where he was a key contributor to the President's National Strategy to Secure Cyberspace, helped initiate the first national cyber security exercise program involving government and the private sector, and served as a senior security adviser on foreign investments for the US government regarding corporate acquisitions and outsourcing concerns in the telecommunications and information technology sector. Rattray also commanded the Operations Group of the AF Information Warfare Center. In this role, he was responsible for collaboration with defense industrial base partners related to advanced persistent cyber threats. He also served from 2007 to 2010 as the chief security adviser to Internet Corporation for Assigned Names and Numbers (ICANN), establishing strategies for ICANN's role in enhancing security and resiliency of the domain name system.

He was the driving force in the establishment of the Cyber Conflict Studies Association to ensure US national efforts were guided by a deeper well of intellectual capital involving private industry, think tanks, government, and academia.
