The Information Sharing Environment (ISE) consists of the people, projects, systems, and agencies that enable responsible information sharing across the national security enterprise. The ISE was established by the Intelligence Reform and Terrorism Prevention Act of 2004 and a direct result of 9/11 Commission recommendations. Law enforcement, defense, and intelligence personnel rely on timely and accurate information to keep America safe, and the ISE makes that happen by:

• Advancing responsible information sharing to further counterterrorism, homeland security, and counter weapons of mass destruction missions
• Improving nationwide decision making by transforming from information ownership to stewardship
• Promoting partnerships across federal, state, local, and tribal governments, the private sector, and internationally

A robust ISE strengthens national security by facilitating the sharing and safeguarding of terrorism-related information. Granted government-wide authority by the U.S. Congress, the ISE serves as a trusted broker, facilitating the development of a network-centric ISE by promoting standards and architecture, security and access, and associated privacy protections.
