The Intelink-U (Unclassified) is a U.S. Government, Joint-use, remotely accessed, and operationally implemented information service that is used to access and process unclassified, publicly availible information only. It provides a protected environment to exchange authorized unclassified, unclassified for official use only, and sensitive but unclassified information among personnel of the Defense, the Diplomatic, the Homeland Security, the Intelligence, and the Law Enforcement communities. The Intelink-U firewalls protect users and allow customers to access the public Internet; thus giving Intelink-U users a single point of access to an unprecedented amount of unclassified open source information.
