The seal of Starfleet Intelligence.

Starfleet Intelligence was an intelligence agency of the Federation Starfleet, tasked with gathering and analyzing information foreign powers in the galaxy and launching covert operations.

(The rogue intelligence division known by some as Section 31 operated separately from Starfleet Intelligence and had no official connection to SI.)
In some continuities, Starfleet Intelligence was a distinct division from Starfleet Security. In other continuities, one division was subordinate to the other.

Rivalries and outright "turf wars" between Starfleet Intelligence and Starfleet Security often went on, unbeknownst to the general public and to most Starfleet personnel. Such a rivalry was known as a "Big Game". (Cloak and Dagger)

Operation Dhalang was a Starfleet Intelligence operation behind Romulan lines in 2294. (Star Trek: Shadowstar Station: "Dhalang")
