A security system and method for preventing unwanted passage through windows and doors of a building includes custom sizing and welding of hardened steel structures that mount into the door jam or window frame, on the inside of the door or window with the use of threaded fasteners. The custom assembled structure consists of an outer frame and horizontal and vertical pickets that may be formed of flat stock, hollow square or rectangular steel tubing or solid square hardened steel bars. The system and method involves specifically spacing the vertical and horizontal pickets so as to lineup with an ornamental structure on the window or door (e.g., grids) without obstructing the view of the door or window so that the steel bars of the security structure is essentially invisible.
