An enclosure for improving padlock security is provided. The enclosure includes a sleeve component that has openings at the left and right for receiving the padlock, cutouts at the top to access the shackle holes and a key slot at the bottom for accessing the padlock. The sleeve component containing the padlock is inserted into a tubular component. The tubular component has an opening at the bottom for receiving the sleeve component and padlock, one or more stoppers, capable of contacting the body of the padlock preventing further insertion of the padlock, while allowing the shackle to continue past, cutouts on the front and back sides of the enclosure beginning at the stoppers and proceeding upward and an opening at the top for accessing the shackle.
