A secure enclosure for resisting attacks using explosives. The secure enclosure has a body defining an opening and a door leaf hingeably coupled to the body for securely closing the opening. The body and door leaf define a cavity in which valuable items may be stored. The secure enclosure also defines a plurality of frangible portions. Each frangible portion comprises a weakened perimeter so that the frangible portions are ejected by the rapid build-up of pressure when an explosion occurs within the secure enclosure, thereby reducing the pressure within the secure enclosure and preserving the integrity of the body and door.
