InfraGard is a non-profit organization serving as a public-private partnership between U.S. businesses and the Federal Bureau of Investigation. The organization describes itself as an information sharing and analysis effort serving the interests and combining the knowledge base of a wide range of members. InfraGard is an association of individuals that facilitates information sharing and intelligence between businesses, academic institutions, state and local law enforcement agencies, and other participants dedicated to prevent hostile acts against the United States. InfraGard's mutual nondisclosure agreements among its members (individuals) and the FBI promotes trusted discussions of vulnerabilities and solutions that companies and individuals may be hesitant to place in the public domain.
The information sharing between the organization and government has been criticized by those protecting civil liberties, concerned the membership would be surrogate eyes and ears for the FBI. The group has also been the subject of hacking attacks intended to embarrass the FBI. Local chapters regularly meet to discuss the latest threats or listen to talks from subject matter experts on security issues, with membership open to U.S. citizens at no cost. As of July, 2012, the organization reported membership at over 54,677 (including FBI).
