SECUR-T or steward-bots, are robots in the Disney/Pixar film WALL-E. At first, they are seen as neutral characters, but later on, they become the overall tertiary antagonists of the film. During the credits, SECUR-T are seen as being neutral again.
The SECUR-T's are the police force of the BNL starliner Axiom. They try to keep things in order aboard the ship. After WALL-E accidentally freed the malfunctioning robots from the Repair Ward, they chased after the "rogue robots". They considered WALL-E and EVE rogues as well.
Later, AUTO summoned all available SECUR-T's to stop EVE and WALL-E from placing the plant in the Axiom's holo-detector, only for all of them to be destroyed by HAN-S (massage-bot).
However, not all SECUR-T's were destroyed. When EVE broke out from the garbage disposal with M-O and WALL-E, they encountered a single SECUR-T unit who was scared off by EVE and hid in a closet after taking a new picture of them. During the credits, a SECUR-T (that could've been the one in the closet) was seen helping the other robots rebuild the city after the Axiom returned to Earth.
