The Giants signed S Stevie Brown on Monday. His agent, Blake Baratz, confirmed the signing on Twitter.
Brown played in eight games last season for the Colts, totaling five tackles. The Colts chose not to tender him as an exclusive-rights free agent, making him an unrestricted free agent March 13.
In 2010, Brown was with the Raiders, where he played in 15 games with one start. He had 30 tackles and two passes defensed.
