IPT maintains a data center that includes archival information relating to the past activities of known Islamic terrorist groups. They also investigate suspected funding activities and networks of Islamic extremists in the US and abroad. IPT obtains information from a variety of sources, including "websites, list-serves, publications, informants, undercover recordings, government records, court documents, and so on". IPT has provided useful evidence to law enforcement and government agencies, and occasionally provides testimonial evidence during special committee hearings of the US Congress.
