Partner Engagement Information Sharing Enviroment

Office of the Director of National Intelligence

Washington, D.C. 20511



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. The Program Manager for the Information Sharing Environment contributes to the strength of the ISE by bringing federal, state, local, tribal, and private sector mission partners together to align the business processes, standards and architecture, security and access controls, privacy protections, and best practices on which the ISE is built. PM-ISE administers this website as part of this effort to collaborate and promote the work of the ISE.


Role of the Office of the PM-ISE

The role of the Program Manager for the Information Sharing Environment (PM-ISE) is to spearhead the nation's efforts to realize the vision of the ISE. Granted government-wide authority by the U.S. Congress, PM-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.


Founded in 2005, PM-ISE is placed within the Office of the Director of National Intelligence (ODNI) to better coordinate the office's terrorism-related information sharing mission with the DNI's mission to improve intelligence information sharing.

Partner Engagement Information Sharing Environment (PE-ISE)


The Intelligence Reform and Terrorism Prevention Act of 2004 (IRTPA) established the Office of the Program Manager for the Information Sharing Environment (PM-ISE) and granted it the authority to plan, oversee, and manage the Information Sharing Environment. PM-ISE was placed within the Office of the Director of National Intelligence (ODNI) Partner Engagement (PE) to better coordinate the office's terrorism-related information sharing mission with the DNI's mission to improve intelligence information sharing. As part of the integration, PM-ISE became PE-ISE. PE-ISE has government-wide authority granted by the Congress to serve as a trusted broker facilitating the development of a network-centric ISE by promoting standards and architecture, security and access, and associated privacy protections.


PE-ISE leverages information sharing capabilities to focus on terrorism-related information sharing, homeland security, and counter proliferation of weapons of mass destruction missions. As a change agent and advocate for sharing of best practices, PE-ISE uses several tools to initiate transformation across all levels of government to include:

  • Providing information sharing subject matter expertise
  • Facilitating automated sharing of terrorism-related information through the Information Sharing Council (chaired by the Program Manager)
  • Working with national leadership via stakeholder engagement with mission partners
  • Encouraging co-investment of seed capital with mission partners in priority early stage activities via Economy Act transactions to bridge the budgeting cycle and accelerate ISE progress
  • Bringing together mission partners to identify and address common mission requirements and goals

PE-ISE develops initiatives in full partnership with mission owners. As business processes, supporting policies, and technical solutions are developed and deployed, PE-ISE assists partners to identify, promote, and spread best practices and, where possible, influence resource allocation decisions to ensure the institutionalization and potential reuse of mission partner capabilities. Seeding new initiatives or transforming existing capabilities is challenging, particularly when government funding constraints and long-lead times make budgeting for new initiatives difficult. PE-ISE has the ability to augment budgetary gaps that prevent an organization from achieving its goals of effective information sharing.


PE-ISE is unique in that it possesses the mandate and the necessary tools to empower, oversee, and advance the ISE. Thanks to our many successful partnerships, the ISE continues grow, making a significant contribution to the safety and security of the American people.
