DHS Office of Intelligence and Analysis I&A

The 9/11 Commission found that warnings had not reached the people who could act on them, and the Homeland Security Act of 2002 gave the new department an intelligence analysis function. A 2007 law implementing the commission's recommendations, signed on August 3, 2007, strengthened the Office of Intelligence and Analysis and its leader, the Under Secretary for Intelligence and Analysis, who is confirmed by the Senate. I&A is one of the eighteen elements of the U.S. intelligence community.

I&A is the only intelligence community member whose main job is sharing information with state, local, tribal, and territorial governments and the private sector. It analyzes threats ranging from terrorism to cyberattacks, drug trafficking, and border security, produces bulletins for law enforcement, and stations officers at about eighty state and local fusion centers, where federal, state, and local agencies pool information. It also oversees the intelligence units of DHS components such as Customs and Border Protection and the Coast Guard.

I&A has faced criticism from across the spectrum. Its 2020 reports on protesters and journalists in Portland, Oregon, led to an internal review and new limits, and its open-source collection on Americans has raised civil liberties concerns. In 2025 the office was sharply reduced and refocused toward immigration, cartels, and border threats. Supporters said the changes trimmed a duplicative bureaucracy, while some state and local officials and former intelligence officials warned of weaker warning networks against domestic attacks.
