Starfleet Intelligence was an intelligence agency of the Lyran Starfleet, tasked with gathering and analyzing information foreign powers in the galaxy and launching covert operations. This was where most non-Lyrans in the Lyran Starfleet that were not in Lyran Starfleet Medical got assigned to, although some Lyrans served in LSI on occasion. This was supposedly to give an appearance of overture towards subject species among Lyrans. (RIS Bouteina)
