ESC operates as a division of the Department of Transportation and is located at the Federal Aviation Administration's Mike Monroney Aeronautical Center in Oklahoma City, Oklahoma. The organization and its service areas are comprised of over 1,200 federal employees and contractors who carry out a mission of service. Paying attention to customer needs has led the ESC to become a provider of choice. ESC takes the time to learn each customer's business processes and requirements, and uses that knowledge to establish expectations and service levels. As a result of such efforts, the ESC can customize a specific support strategy for each and every customer. In February of 2005, the Office of Management and Budget (OMB) named ESC as a Financial Management Center of Excellence and Shared Service Provider. Then in January 2009, ESC earned the designation of being one of only six Information Systems Security (ISS) Line of Business Shared Service Providers. In 2012, ESC became the only government entity to achieve 3rd Party Assessment Organization (3PAO) certification, which indicates the rigorous industry standards ESC applies to cybersecurity and cloud computing.
