An apparatus for reducing the vulnerability to unauthorized entry past a r comprising a first rectangular shaped plate attached to the outside of the door, the first plate having a second or strike plate positioned to extend into the door frame to resist separation of the door and its door frame when the door is closed. The apparatus further comprises a third rectangular shaped plate attached to the inside of the door and communicating with the first plate. A portion of the first plate extends beyond the door covering a portion of the door frame. The apparatus is adapted to receive a door locking mechanism having a dead bolt. When the door is in a closed position and the dead bolt is activated, the dead bolt is extended through a pair of apertures in the door frame. Extending the dead bolt through the pair of apertures in the door frame reinforces the door and door frame and places all applied loads during forced entry directly to the dead bolt via double shear.
