An embodiment in accordance with the present invention provides a device that is easily deployable on almost any style of door and prevents an intruder from opening the door. The device has a thin flat profile that is easily slid under a door and is also easily stored. The device includes a portion that engages the floor and the door to prevent the door from opening. The geometry of the portion that engages the floor and the door is such that the upward force on the door is increased when the door is either pushed or pulled. The harder an intruder pushes or pulls on the door, the more the device will grip both the door and floor itself. The device also includes a kickstand to keep the device in place and allow for easy removal.
